<h2 id="id00876" style="margin-top: 4em">CHAPTER V</h2>
<h5 id="id00877">THE POISONED ROOM</h5>
<p id="id00878" style="margin-top: 2em">Elaine and Craig were much together during the next few days.</p>
<p id="id00879">Somehow or other, it seemed that the chase of the Clutching Hand
involved long conferences in the Dodge library and even, in fact,
extended to excursions into that notoriously crime-infested
neighborhood of Riverside Drive with its fashionable processions of
automobiles and go-carts—as far north, indeed, as that desperate haunt
known as Grant's Tomb.</p>
<p id="id00880">More than that, these delvings into the underworld involved Kennedy in
the necessity of wearing a frock coat and silk hat in the afternoon,
and I found that he was selecting his neckwear with a care that had
been utterly foreign to him during all the years previous that I had
known him.</p>
<p id="id00881">It all looked very suspicious to me.</p>
<p id="id00882">But, to return to the more serious side of the affair.</p>
<p id="id00883">Kennedy and Elaine had scarcely come out of the house and descended the
steps, one afternoon, when a sinister face appeared in a basement
areaway nearby.</p>
<p id="id00884">The figure was crouched over, with his back humped up almost as if
deformed, and his left hand had an unmistakable twist.</p>
<p id="id00885">It was the Clutching Hand.</p>
<p id="id00886">He wore a telephone inspector's hat and coat and carried a bag slung by
a strap over his shoulder. For once he had left off his mask, but, in
place of it, his face was covered by a scraggly black beard. In fact,
he seemed to avoid turning his face full, three-quarters or even
profile to anyone, unless he had to do so. As much as possible he
averted it, but he did so in a clever way that made it seem quite
natural. The disguise was effective.</p>
<p id="id00887">He saw Kennedy and Miss Dodge and slunk unobtrusively against a
railing, with his head turned away. Laughing and chatting, they passed.
As they walked down the street, Clutching Hand turned and gazed after
them. Involuntarily the menacing hand clutched in open hatred.</p>
<p id="id00888">Then he turned in the other direction and, going up the steps of the<br/>
Dodge house, rang the bell.<br/></p>
<p id="id00889">"Telephone inspector," he said in a loud tone as Michael, in Jennings'
place for the afternoon, opened the door.</p>
<p id="id00890">He accompanied the words with the sign and Michael, taking care that
the words be heard, in case anyone was listening, admitted him.</p>
<p id="id00891">As it happened, Aunt Josephine was upstairs in Elaine's room. She was
fixing flowers in a vase on the dressing table of her idolized niece.
Meanwhile, Rusty, the collie, lay, half blinking, on the floor.</p>
<p id="id00892">"Who is this?" she asked, as Michael led the bogus telephone inspector
into the room.</p>
<p id="id00893">"A man from the telephone company," he answered deferentially.</p>
<p id="id00894">Aunt Josephine, unsophisticated, allowed them to enter without a
further question.</p>
<p id="id00895">Quickly, like a good workman, Clutching Hand went to the telephone
instrument and by dint of keeping his finger on the hook and his back
to Aunt Josephine succeeded in conveying the illusion that he was
examining it.</p>
<p id="id00896">Aunt Josephine moved to the door. Not so, Rusty. He did not like the
looks of the stranger and he had no scruples against letting it be
known.</p>
<p id="id00897">As she put her hand on the knob to go out into the hall, Rusty uttered
a low growl which grew into a full-lunged snarl at the Clutching Hand.
Clutching Hand kicked at him vigorously, if surreptitiously. Rusty
barked.</p>
<p id="id00898">"Lady," he disguised his voice, "will yer please ter call off the dog?<br/>
Me and him don't seem to cotton to each other."<br/></p>
<p id="id00899">"Here, Rusty," she commanded, "down!"</p>
<p id="id00900">Together Aunt Josephine and Michael removed the still protesting Rusty.</p>
<p id="id00901">No sooner was the door shut than the Clutching Hand moved over swiftly
to it. For a few seconds, he stood gazing at them as they disappeared
down-stairs. Then he came back into the center of the room.</p>
<p id="id00902">Hastily he opened his bag and from it drew a small powder-spraying
outfit such as I have seen used for spraying bug-powder. He then took
out a sort of muzzle with an elastic band on it and slipped it over his
head so that the muzzle protected his nose and mouth.</p>
<p id="id00903">He seemed to work a sort of pumping attachment and from the nozzle of
the spraying instrument blew out a cloud of powder which he directed at
the wall.</p>
<p id="id00904">The wall paper was one of those rich, fuzzy varieties and it seemed to
catch the powder. Clutching Hand appeared to be more than satisfied
with the effect.</p>
<p id="id00905">Meanwhile, Michael, in the hallway, on guard to see that no one
bothered the Clutching Hand at his work, was overcome by curiosity to
see what his master was doing. He opened the door a little bit and
gazed stealthily through the crack into the room.</p>
<p id="id00906">Clutching Hand was now spraying the rug close to the dressing table of
Elaine and was standing near the mirror. He stooped down to examine the
rug. Then, as he raised his head, he happened to look into the mirror.
In it he could see the full reflection of Michael behind him, gazing
into the room.</p>
<p id="id00907">"The scoundrel!" muttered Clutching Hand, with repressed fury at the
discovery.</p>
<p id="id00908">He rose quickly and shut off the spraying instrument, stuffing it into
the bag. He took a step or two toward the door. Michael drew back,
fearfully, pretending now to be on guard.</p>
<p id="id00909">Clutching Hand opened the door and, still wearing the muzzle, beckoned
to Michael. Michael could scarcely control his fears. But he obeyed,
entering Elaine's room after the Clutching Hand, who locked the door.</p>
<p id="id00910">"Were you watching me?" demanded the master criminal, with rage.</p>
<p id="id00911">Michael, trembling all over, shook his head. For a moment Clutching<br/>
Hand looked him over disdainfully at the clumsy lie.<br/></p>
<p id="id00912">Then he brutally struck Michael in the face, knocking him down. An
ungovernable, almost insane fury seemed to possess the man as he stood
over the prostrate footman, cursing.</p>
<p id="id00913">"Get up!" he ordered.</p>
<p id="id00914">Michael obeyed, thoroughly cowed.</p>
<p id="id00915">"Take me to the cellar, now," he demanded.</p>
<p id="id00916">Michael led the way from the room without a protest, the master
criminal following him closely.</p>
<p id="id00917">Down into the cellar, by a back way, they went, Clutching Hand still
wearing his muzzle and Michael saying not a word.</p>
<p id="id00918">Suddenly Clutching Hand turned on him and seized him by the collar.</p>
<p id="id00919">"Now, go upstairs, you," he muttered, shaking him until his teeth
fairly chattered, "and if you watch me again—I'll kill you!"</p>
<p id="id00920">He thrust Michael away and the footman, overcome by fear, hurried
upstairs. Still trembling and fearful, Michael paused In the hallway,
looking back resentfully, for even one who is in the power of a
super-criminal is still human and has feelings that may be injured.</p>
<p id="id00921">Michael put his hand on his face where the Clutching Hand had struck
him. There he waited, muttering to himself. As he thought it over,
anger took the place of fear. He slowly turned in the direction of the
cellar. Closing both his fists, Michael made a threatening gesture at
his master in crime.</p>
<p id="id00922">Meanwhile, Clutching Hand was standing by the electric meter. He
examined it carefully, feeling where the wires entered and left it
starting to trace them out. At last he came to a point where it seemed
suitable to make a connection for some purpose he had in mind.</p>
<p id="id00923">Quickly he took some wire from his bag and connected it with the
electric light wires. Next, he led these wires, concealed of course,
along the cellar floor, in the direction of the furnace.</p>
<p id="id00924">The furnace was one of the old hot air heaters and he paused before it
as though seeking something. Then he bent down beside it and uncovered
a little tank. He took off the top on which were cast in the iron the
words:</p>
<p id="id00925">"This tank must be kept full of water."</p>
<p id="id00926">He thrust his hand gingerly into it, bringing it out quickly. The tank
was nearly full of water and he brought his hand out wet. It was also
hot. But he did not seem to mind that, for he shook his head with a
smile of satisfaction.</p>
<p id="id00927">Next, from his capacious bag he took two metal poles, or electrodes,
and fastened them carefully to the ends of the wires, placing them at
opposite ends of the tank in the water.</p>
<p id="id00928">For several moments he watched. The water inside the tank seemed the
same as before, only on each electrode there appeared bubbles, on one
bubbles of oxygen, on the other of hydrogen. The water was decomposing
under the current by electrolysis.</p>
<p id="id00929">Another moment he surveyed his work to see that he had left no loose
ends. Then he picked up his bag and moved toward the cellar steps. As
he did so, he removed the muzzle from his nose and quietly let himself
out of the house.</p>
<p id="id00930"> . . . . . . . .</p>
<p id="id00931">The next morning, Rusty, who had been Elaine's constant companion since
the trouble had begun, awakened his mistress by licking her hand as it
hung limply over the side of her bed.</p>
<p id="id00932">She awakened with a start and put her hand to her head. She felt ill.</p>
<p id="id00933">"Poor old fellow," she murmured, half dazedly, for the moment endowing
her pet with her own feelings, as she patted his faithful shaggy head.</p>
<p id="id00934">Rusty moved away again, wagging his tail listlessly. The collie, too,
felt ill. Elaine watched him as he walked, dejected, across the room
and then lay down.</p>
<p id="id00935">"Why, Miss Elaine—what ees ze mattair? You are so pale!" exclaimed the
maid, Marie, as she entered the room a moment later with the morning's
mail on a salver.</p>
<p id="id00936">"I don't feel well, Marie," she replied, trying with her slender white
hand to brush the cobwebs from her brain. "I—I wish you'd tell Aunt
Josephine to telephone Dr. Hayward."</p>
<p id="id00937">"Yes, mademoiselle," answered Marie, deftly and sympathetically
straightening out the pillows.</p>
<p id="id00938">Languidly Elaine took the letters one by one off the salver. She looked
at them, but seemed not to have energy enough to open them.</p>
<p id="id00939">Finally she selected one and slowly tore it open. It had no
superscription, but it at once arrested her attention and transfixed
her with terror.</p>
<p id="id00940">It read:</p>
<h5 id="id00941">"YOU ARE SICK THIS MORNING. TOMORROW YOU WILL BE WORSE. THE NEXT DAY
YOU WILL DIE UNLESS YOU DISCHARGE CRAIG KENNEDY."</h5>
<p id="id00942">It was signed by the mystic trademark of the fearsome Clutching Hand!</p>
<p id="id00943">Elaine drew back into the pillows, horror stricken.</p>
<p id="id00944">Quickly she called to Marie. "Go—get Aunt Josephine—right away!"</p>
<p id="id00945">As Marie almost flew down the hall, Elaine still holding the letter
convulsively, pulled herself together and got up, trembling. She almost
seized the telephone as she called Kennedy's number.</p>
<p id="id00946"> . . . . . . . .</p>
<p id="id00947">Kennedy, in his stained laboratory apron, was at work before his table,
while I was watching him with intense interest, when the telephone rang.</p>
<p id="id00948">Without a word he answered the call and I could see a look of
perturbation cross his face. I knew it was from Elaine, but could tell
nothing about the nature of the message.</p>
<p id="id00949">An instant later he almost tore off the apron and threw on his hat and
coat. I followed him as he dashed out of the laboratory.</p>
<p id="id00950">"This is terrible—terrible," he muttered, as we hurried across the
campus of the University to a taxi-cab stand.</p>
<p id="id00951">A few minutes later, when we arrived at the Dodge mansion, we found
Aunt Josephine and Marie doing all they could under the circumstances.
Aunt Josephine had just given her a glass of water which she drank
eagerly. Rusty had, meanwhile, crawled under the bed, caring only to be
alone and undisturbed.</p>
<p id="id00952">Dr. Hayward had arrived and had just finished taking her pulse and
temperature as our cab pulled up.</p>
<p id="id00953">Jennings who had evidently been expecting us let us in without a word
and conducted us up to Elaine's room. We knocked.</p>
<p id="id00954">"Mr. Kennedy and Mr. Jameson," we could hear Marie whisper in a subdued
voice.</p>
<p id="id00955">"Tell them to come in," answered Elaine eagerly.</p>
<p id="id00956">We entered. There she lay, beautiful as ever, but with a whiteness of
her fresh cheek that was too etherially unnatural. Elaine was quite ill
indeed.</p>
<p id="id00957">"Oh—I'm so glad to see you," she breathed, with an air of relief as<br/>
Kennedy advanced.<br/></p>
<p id="id00958">"Why—what is the matter?" asked Craig, anxiously.</p>
<p id="id00959">Dr. Hayward shook his head dubiously, but Kennedy did not notice him,
for, as he approached Elaine, she drew from the covers where she had
concealed it a letter and handed it to him.</p>
<p id="id00960">Craig took it and read:</p>
<h5 id="id00961">"YOU ARE SICK THIS MORNING. TOMORROW YOU WILL BE WORSE. THE NEXT DAY
YOU WILL DIE UNLESS YOU DISCHARGE CRAIG KENNEDY."</h5>
<p id="id00962">At the signature of the Clutching Hand he frowned, then, noticing Dr.<br/>
Hayward, turned to him and repeated his question, "What is the matter?"<br/></p>
<p id="id00963">Dr. Hayward continued shaking his head. "I cannot diagnose her
symptoms," he shrugged.</p>
<p id="id00964">As I watched Kennedy's face, I saw his nostrils dilating, almost as if
he were a hound and had scented his quarry. I sniffed, too. There
seemed to be a faint odor, almost as if of garlic, in the room. It was
unmistakable and Craig looked about him curiously but said nothing.</p>
<p id="id00965">As he sniffed, he moved impatiently and his foot touched Rusty, under
the bed. Rusty whined and moved back lazily. Craig bent over and looked
at him.</p>
<p id="id00966">"What's the matter with Rusty?" he asked. "Is he sick, too?"</p>
<p id="id00967">"Why—yes," answered Elaine, following Craig with her deep eyes. "Poor
Rusty. He woke me up this morning. He feels as badly as I do, poor old
fellow."</p>
<p id="id00968">Craig reached down and gently pulled the collie out into the room.
Rusty crouched down close to the floor. His nose was hot and dry and
feverish. He was plainly ill.</p>
<p id="id00969">"How long has Rusty been in the room?" asked Craig.</p>
<p id="id00970">"All night," answered Elaine. "I wouldn't think of being without him
now."</p>
<p id="id00971">Kennedy lifted the dog by his front paws. Rusty submitted patiently,
but without any spirit.</p>
<p id="id00972">"May I take Rusty along with me?" he asked finally.</p>
<p id="id00973">Elaine hesitated. "Surely," she said at length, "only, be gentle with
him."</p>
<p id="id00974">Craig looked at her as though it would be impossible to be otherwise
with anything belonging to Elaine.</p>
<p id="id00975">"Of course," he said simply. "I thought that I might be able to
discover the trouble from studying him."</p>
<p id="id00976">We stayed only a few minutes longer, for Kennedy seemed to realize the
necessity of doing something immediately and even Dr. Hayward was
fighting in the dark. As for me, I gave it up, too. I could find no
answer to the mystery of what was the peculiar malady of Elaine.</p>
<p id="id00977">Back in the laboratory, Kennedy set to work immediately, brushing
everything else aside. He began by drawing off a little of Rusty's
blood in a tube, very carefully.</p>
<p id="id00978">"Here, Walter," he said pointing to the little incision he had made.<br/>
"Will you take care of him?"<br/></p>
<p id="id00979">I bound up the wounded leg and gave the poor beast a drink of water.
Rusty looked at me gratefully from his big sad brown eyes. He seemed to
appreciate our gentleness and to realize that we were trying to help
him.</p>
<p id="id00980">In the meantime, Craig had taken a flask with a rubber stopper. Through
one hole in it was fitted a long funnel; through another ran a glass
tube. The tube connected with a large U-shaped drying tube filled with
calcium chloride, which, in turn, connected with a long open tube with
an upturned end.</p>
<p id="id00981">Into the flask, Craig dropped some pure granulated zinc. Then he
covered it with dilute sulphuric acid, poured in through the funnel
tube.</p>
<p id="id00982">"That forms hydrogen gas," he explained to me, "which passes through
the drying tube and the ignition tube. Wait a moment until all the air
is expelled from the tubes."</p>
<p id="id00983">He lighted a match and touched it to the open, upturned end. The
hydrogen, now escaping freely, was ignited with a pale blue flame.</p>
<p id="id00984">A few moments later, having extracted something like a serum from the
blood he had drawn off from Rusty. He added the extract to the mixture
in the flask, pouring it in, also through the funnel tube.</p>
<p id="id00985">Almost immediately the pale, bluish flame turned to bluish white, and
white fumes were formed. In the ignition tube a sort of metallic
deposit appeared.</p>
<p id="id00986">Quickly Craig made one test after another.</p>
<p id="id00987">As he did so, I sniffed. There was an unmistakable odor of garlic in
the air which made me think of what I had already noticed in Elaine's
room.</p>
<p id="id00988">"What is it?" I asked, mystified.</p>
<p id="id00989">"Arseniuretted hydrogen," he answered, still engaged in verifying his
tests. "This is the Marsh test for arsenic."</p>
<p id="id00990">I gazed from Kennedy to the apparatus, then to Rusty and a picture of<br/>
Elaine, pale and listless, flashed before me.<br/></p>
<p id="id00991">"Arsenic!" I repeated in horror.</p>
<p id="id00992"> . . . . . . . .</p>
<p id="id00993">I had scarcely recovered from the surprise of Kennedy's startling
revelation when the telephone rang again. Kennedy seized the receiver,
thinking evidently that the message might be from or about Elaine.</p>
<p id="id00994">But from the look on his face and from his manner, I could gather that,
although it was not from Elaine herself, it was about something that
interested him greatly. As he talked, he took his little notebook and
hastily jotted down something in it. Still, I could not make out what
the conversation was about.</p>
<p id="id00995">"Good!" I heard him say finally. "I shall keep the
appointment—absolutely."</p>
<p id="id00996">His face wore a peculiar puzzled look as he hung up the receiver.</p>
<p id="id00997">"What was it?" I asked eagerly.</p>
<p id="id00998">"It was Elaine's footman, Michael," he replied thoughtfully. "As I
suspected, he says that he is a confederate of the Clutching Hand and
if we will protect him he will tell us the trouble with Elaine."</p>
<p id="id00999">I considered a moment. "How's that?" I queried.</p>
<p id="id01000">"Well," added Craig, "you see, Michael has become infuriated by the
treatment he received from the Clutching Hand. I believe he cuffed him
in the face yesterday. Anyway, he says he has determined to get even
and betray him. So, after hearing how Elaine was, he slipped out of the
servant's door and looking about carefully to see that he wasn't
followed, he went straight to a drug store and called me up. He seemed
extremely nervous and fearful."</p>
<p id="id01001">I did not like the looks of the thing, and said so. "Craig," I objected
vehemently, "don't go to meet him. It is a trap."</p>
<p id="id01002">Kennedy had evidently considered my objection already.</p>
<p id="id01003">"It may be a trap," he replied slowly, "but Elaine is dying and we've
got to see this thing through."</p>
<p id="id01004">As he spoke, he took an automatic from a drawer of a cabinet and thrust
it into his pocket. Then he went to another drawer and took out several
sections of thin tubing which seemed to be made to fasten together as a
fishing pole is fastened, but were now separate, as if ready for
travelling.</p>
<p id="id01005">"Well—are you coming, Walter?" he asked finally—the only answer to my
flood of caution.</p>
<p id="id01006">Then he went out. I followed, still arguing.</p>
<p id="id01007">"If YOU go, <i>I</i> go," I capitulated. "That's all there is to it."</p>
<p id="id01008">Following the directions that Michael had given over the telephone<br/>
Craig led me into one of the toughest parts of the lower West Side.<br/></p>
<p id="id01009">"Here's the place," he announced, stopping across the street from a
dingy Raines Law Hotel.</p>
<p id="id01010">"Pretty tough," I objected. "Are you sure?"</p>
<p id="id01011">"Quite," replied Kennedy, consulting his note book again.</p>
<p id="id01012">"Well, I'll be hanged if I'll go in that joint," I persisted.</p>
<p id="id01013">It had no effect on Kennedy. "Nonsense, Walter," he replied, crossing
the street.</p>
<p id="id01014">Reluctantly I followed and we entered the place.</p>
<p id="id01015">"I want a room," asked Craig as we were accosted by the proprietor,
comfortably clad in a loud checked suit and striped shirt sleeves. "I
had one here once before—forty-nine, I think."</p>
<p id="id01016">"Fifty—" I began to correct.</p>
<p id="id01017">Kennedy trod hard on my toes.</p>
<p id="id01018">"Yes, forty-nine," he repeated.</p>
<p id="id01019">The proprietor called a stout negro porter, waiter, and bell-hop all
combined in one, who led us upstairs.</p>
<p id="id01020">"Fohty-nine, sah," he pointed out, as Kennedy dropped a dime into his
ready palm.</p>
<p id="id01021">The negro left us and as Craig started to enter, I objected, "But,<br/>
Craig, it was fifty-nine, not forty-nine. This is the wrong room."<br/></p>
<p id="id01022">"I know it," he replied. "I had it written in the book. But I want
forty-nine—now. Just follow me, Walter."</p>
<p id="id01023">Nervously I followed him into the room.</p>
<p id="id01024">"Don't you understand?" he went on. "Room forty-nine is probably just
the same as fifty-nine, except perhaps the pictures and furniture, only
it is on the floor below."</p>
<p id="id01025">He gazed about keenly. Then he took a few steps to the window and threw
it open. As he stood there he took the parts of the rods he had been
carrying and fitted them together until he had a pole some eight or ten
feet long. At one end was a curious arrangement that seemed to contain
lenses and a mirror. At the other end was an eye-piece, as nearly as I
could make out.</p>
<p id="id01026">"What is that?" I asked as he completed his work.</p>
<p id="id01027">"That? That is an instrument something on the order of a miniature
submarine periscope," Craig replied, still at work.</p>
<p id="id01028">I watched him, fascinated at his resourcefulness. He stealthily thrust
the mirror end of the periscope out of the window and up toward the
corresponding window up stairs. Then he gazed eagerly through the
eye-piece.</p>
<p id="id01029">"Walter—look!" he exclaimed to me.</p>
<p id="id01030">I did. There, sure enough, was Michael, pacing up and down the room. He
had already preceded us. In his scared and stealthy manner, he had
entered the Raines Law hotel which announced "Furnished Rooms for
Gentlemen Only." There he had sought a room, fifty-nine, as he had said.</p>
<p id="id01031">As he came into the room, he had looked about, overcome by the enormity
of what he was about to do. He locked the door. Still, he had not been
able to avoid gazing about fearfully, as he was doing now that we saw
him.</p>
<p id="id01032">Nothing had happened. Yet he brushed his hand over his forehead and
breathed a sigh of relief. The air seemed to be stifling him and
already he had gone to the window and thrown it open. Then he had gazed
out as though there might be some unknown peril in the very air. He had
now drawn back from the window and was considering. He was actually
trembling. Should he flee? He whistled softly to himself to keep his
shaking fears under control. Then he started to pace up and down the
room in nervous impatience and irresolution.</p>
<p id="id01033">As I looked at him nervously walking to and fro, I could not help
admitting that things looked safe enough and all right to me. Kennedy
folded the periscope up and we left our room, mounting the remaining
flight of stairs.</p>
<p id="id01034">In fifty-nine we could hear the measured step of the footman. Craig
knocked. The footsteps ceased. Then the door opened slowly and I could
see a cold blue automatic.</p>
<p id="id01035">"Look out!" I cried.</p>
<p id="id01036">Michael in his fear had drawn a gun.</p>
<p id="id01037">"It's all right, Michael," reassured Craig calmly. "All right, Walter,"
he added to me.</p>
<p id="id01038">The gun dropped back into the footman's pocket. We entered and Michael
again locked the door. Not a word had been spoken by him so far.</p>
<p id="id01039">Next Michael moved to the center of the room and, as I realized later,
brought himself in direct lines with the open window. He seemed to be
overcome with fear at his betrayal and stood there breathing heavily.</p>
<p id="id01040">"Professor Kennedy," he began, "I have been so mistreated that I have
made up my mind to tell you all I know about this Clutching—"</p>
<p id="id01041">Suddenly he drew a sharp breath and both his hands clutched at his own
breast. He did not stagger and fall in the ordinary manner, but seemed
to bend at the knees and waist and literally crumple down on his face.</p>
<p id="id01042">We ran to him. Craig turned him over gently on his back and examined
him. He called. No answer. Michael was almost pulseless.</p>
<p id="id01043">Quickly Craig tore off his collar and bared his breast, for the man
seemed to be struggling for breath. As he did so, he drew from
Michael's chest a small, sharp-pointed dart.</p>
<p id="id01044">"What's that?" I ejaculated, horror stricken.</p>
<p id="id01045">"A poisoned blow gun dart such as is used by the South American Indians
on the upper Orinoco," he said slowly.</p>
<p id="id01046">He examined it carefully.</p>
<p id="id01047">"What is the poison?" I asked.</p>
<p id="id01048">"Curari," he replied simply. "It acts on the respiratory muscles,
paralyzing them, and causing asphyxiation."</p>
<p id="id01049">The dart seemed to have been made of a quill with a very sharp point,
hollow, and containing the deadly poison in the sharpened end.</p>
<p id="id01050">"Look out!" I cautioned as he handled it.</p>
<p id="id01051">"Oh, that's all right," he answered casually. "If I don't scratch
myself, I am safe enough. I could swallow the stuff and it wouldn't
hurt me—unless I had an abrasion of the lips or some internal cut."</p>
<p id="id01052">Kennedy continued to examine the dart until suddenly I heard a low
exclamation of surprise from him. Inside the hollow quill was a thin
sheet of tissue paper, tightly rolled. He drew it out and read:</p>
<p id="id01053">"To know me is DEATH Kennedy—Take Warning!"</p>
<p id="id01054">Underneath was the inevitable Clutching Hand sign.</p>
<p id="id01055">We jumped to our feet. Kennedy rushed to the window and slammed it
shut, while I seized the key from Michael's pocket, opened the door and
called for help.</p>
<p id="id01056">A moment before, on the roof of a building across the street, one might
have seen a bent, skulking figure. His face was copper colored and on
his head was a thick thatch of matted hair. He looked like a South
American Indian, in a very dilapidated suit of castoff American clothes.</p>
<p id="id01057">He had slipped out through a doorway leading to a flight of steps from
the roof to the hallway of the tenement. His fatal dart sent on its
unerring mission with a precision born of long years in the South
American jungle, he concealed the deadly blow-gun in his breast pocket,
with a cruel smile, and, like one of his native venomous serpents,
wormed his way down the stairs again.</p>
<p id="id01058"> . . . . . . . .</p>
<p id="id01059">My outcry brought a veritable battalion of aid. The hotel proprietor,
the negro waiter, and several others dashed upstairs, followed shortly
by a portly policeman, puffing at the exertion.</p>
<p id="id01060">"What's the matter, here?" he panted. "Ye're all under arrest!"</p>
<p id="id01061">Kennedy quietly pulled out his card case and taking the policeman aside
showed it to him.</p>
<p id="id01062">"We had an appointment to meet this man—in that Clutching Hand case,
you know. He is Miss Dodge's footman," Craig explained.</p>
<p id="id01063">Then he took the policeman into his confidence, showing him the dart
and explaining about the poison. The officer stared blankly.</p>
<p id="id01064">"I must get away, too," hurried on Craig. "Officer, I will leave you to
take charge here. You can depend on me for the inquest."</p>
<p id="id01065">The officer nodded.</p>
<p id="id01066">"Come on, Walter," whispered Craig, eager to get away, then adding the
one word, "Elaine!"</p>
<p id="id01067">I followed hastily, not slow to understand his fear for her.</p>
<p id="id01068">Nor were Craig's fears groundless. In spite of all that could be done
for her, Elaine was still in bed, much weaker now than before. While we
had been gone, Dr. Hayward, Aunt Josephine and Marie were distracted.</p>
<p id="id01069">More than that, the Clutching Hand had not neglected the opportunity,
either.</p>
<p id="id01070">Suddenly, just before our return, a stone had come hurtling through the
window, without warning of any kind, and had landed on Elaine's bed.</p>
<p id="id01071">Below, as we learned some time afterwards, a car had drawn up hastily
and the evil-faced crook whom the Clutching Hand had used to rid
himself of the informer, "Limpy Red," had leaped out and hurled the
stone through the window, as quickly leaping back into the car and
whisking away.</p>
<p id="id01072">Elaine had screamed. All had reached for the stone. But she had been
the first to seize it and discover that around it was wrapped a piece
of paper on which was the ominous warning, signed as usual by the Hand:</p>
<p id="id01073">"Michael is dead. Tomorrow, you. Then Kennedy. Stop before it is too
late."</p>
<p id="id01074">Elaine had sunk back into her pillows, paler than ever from this second
shock, while the others, as they read the note, were overcome by alarm
and despair, at the suddenness of the thing.</p>
<p id="id01075">It was just then that Kennedy and I arrived and were admitted.</p>
<p id="id01076">"Oh, Mr. Kennedy," cried Elaine, handing him the note.</p>
<p id="id01077">Craig took it and read. "Miss Dodge," he said, as he held the note out
to me, "you are suffering from arsenic poisoning—but I don't know yet
how it is being administered."</p>
<p id="id01078">He gazed about keenly. Meanwhile, I had taken the crumpled note from
him and was reading it. Somehow, I had leaned against the wall. As I
turned, Craig happened to glance at me.</p>
<p id="id01079">"For heaven's sake, Walter," I heard him exclaim. "What have you been
up against?"</p>
<p id="id01080">He fairly leaped at me and I felt him examining my shoulder where I had
been leaning on the wall. Something on the paper had come off and had
left a white mark on my shoulder. Craig looked puzzled from me to the
wall.</p>
<p id="id01081">"Arsenic!" he cried.</p>
<p id="id01082">He whipped out a pocket lens and looked at the paper. "This heavy fuzzy
paper is fairly loaded with it, powdered," he reported.</p>
<p id="id01083">I looked, too. The powdered arsenic was plainly discernible. "Yes, here
it is," he continued, standing absorbed in thought. "But why did it
work so effectively?"</p>
<p id="id01084">He sniffed as he had before. So did I. There was still the faint smell
of garlic. Kennedy paced the room. Suddenly, pausing by the register,
an idea seemed to strike him.</p>
<p id="id01085">"Walter," he whispered, "come down cellar with me."</p>
<p id="id01086">"Oh—be careful," cried Elaine, anxious for him.</p>
<p id="id01087">"I will," he called back.</p>
<p id="id01088">As he flashed his pocket electric bull's-eye about, his gaze fell on
the electric meter. He paused before it. In spite of the fact that it
was broad daylight, it was running. His face puckered.</p>
<p id="id01089">"They are using no current at present in the house," he ruminated. "Yet
the meter is running."</p>
<p id="id01090">He continued to examine the meter. Then he began to follow the electric
wires along. At last he discovered a place where they had been tampered
with and tapped by other wires.</p>
<p id="id01091">"The work of the Clutching Hand!" he muttered.</p>
<p id="id01092">Eagerly he followed the wires to the furnace and around to the back.<br/>
There they led right into a little water tank. Kennedy yanked them out.<br/>
As he did so he pulled something with them.<br/></p>
<p id="id01093">"Two electrodes—the villain placed there," he exclaimed, holding them
up triumphantly for me to see.</p>
<p id="id01094">"Y-yes," I replied dubiously, "but what does it all mean?"</p>
<p id="id01095">"Why, don't you see? Under the influence of the electric current the
water was decomposed and gave off oxygen and hydrogen. The free
hydrogen passed up the furnace pipe and combining with the arsenic in
the wall paper formed the deadly arseniuretted hydrogen."</p>
<p id="id01096">He cast the whole improvised electrolysis apparatus on the floor and
dashed up the cellar steps.</p>
<p id="id01097">"I've found it!" he cried, hurrying into Elaine's room. "It's in this
room—a deadly gas—arseniuretted hydrogen."</p>
<p id="id01098">He tore open the windows and threw them all open. "Have her moved," he
cried to Aunt Josephine. "Then have a vacuum cleaner go over every inch
of wall, carpet and upholstery."</p>
<p id="id01099">Standing beside her, he breathlessly explained his discovery. "That
wall paper has been loaded down with arsenic, probably Paris green or
Schweinfurth green, which is aceto-arsenite of copper. Every minute you
are here, you are breathing arseniuretted hydrogen. The Clutching Hand
has cleverly contrived to introduce the nascent gas into the room. That
acts on the arsenic compounds in the wall paper and hangings and sets
free the gas. I thought I knew the smell the moment I got a whiff of
it. You are slowly being poisoned by minute quantities of the deadly
gas. This Clutching Hand is a diabolical genius. Think of it—poisoned
wall paper!"</p>
<p id="id01100">No one said a word. Kennedy reached down and took the two Clutching
Hand messages Elaine had received. "I shall want to study these notes,
more, too," he said, holding them up to the wall at the head of the bed
as he flashed his pocket lens at them. "You see, Elaine, I may be able
to get something from studying the ink, the paper, the handwriting—"</p>
<p id="id01101">Suddenly both leaped back, with a cry.</p>
<p id="id01102">Their faces had been several inches apart. Something had whizzed
between them and literally impaled the two notes on the wall.</p>
<p id="id01103">Down the street, on the roof of a carriage house, back of a neighbor's,<br/>
might have been seen the uncouth figure of the dilapidated South<br/>
American Indian crouching behind a chimney and gazing intently at the<br/>
Dodge house.<br/></p>
<p id="id01104">As Craig had thrown open Elaine's window and turned to Elaine, the
figure had crouched closer to his chimney.</p>
<p id="id01105">Then with an uncanny determination he slowly raised the blow-gun to his
lips.</p>
<p id="id01106">I jumped forward, followed by Dr. Hayward, Aunt Josephine, and Marie.
Kennedy had a peculiar look as he pulled out from the wall a blow-gun
dart similar in every way to that which had killed Michael.</p>
<p id="id01107">"Craig!" gasped Elaine, reaching up and laying her soft white hand on
his arm in undisguised fear for him, "you—you must give up this chase
for the Clutching Hand!"</p>
<p id="id01108">"Give up the chase for the Clutching Hand?" he repeated in surprise.<br/>
"Never! Not until either he or I is dead!"<br/></p>
<p id="id01109">There was both fear and admiration mingled in her look, as he reached
down and patted her dainty shoulder encouragingly.</p>
