<h5 id="id01330">THE VOICE FROM THE AIR</h5>
<p id="id01331" style="margin-top: 2em">"Do you believe it?" I asked Kennedy, as the voices died away, leaving
us with a feeling that some one had gone out of the very room in which
we were.</p>
<p id="id01332">He shrugged his shoulders and said nothing. But I cannot say that he
seemed ill pleased at the result of the interview.</p>
<p id="id01333">"We'll just keep this vocaphone in," he remarked. "It may come in handy
some time. Now, I think we had better go back to the laboratory! Things
have begun to move."</p>
<p id="id01334">On the way back he stopped to telephone Norton to meet us and a few
minutes after we arrived, the archaeologist entered.</p>
<p id="id01335">Kennedy lost no time in coming directly to the point, and Norton could
see, in fact seemed to expect and be prepared for what was coming.</p>
<p id="id01336">"Well," exclaimed Kennedy, "you've done it, this time!"</p>
<p id="id01337">"I know what you are going to ask," returned Norton. "You are going to
ask me why I did it. And I'm going to tell you. After I left you, the
other day, I thought about it a long time. The more I thought, the more
of a shame it seemed to me that a girl like that should be made a
victim of her feelings. It wasn't so much what they have done to me
that made me do it. I would have acted the same if it had been de Moche
instead of Lockwood who was playing on her heart. I was afraid, to tell
the truth, that you wouldn't tell her until it was too late. And she's
too good to throw herself away and allow her fortune to be wasted by a
couple of speculators."</p>
<p id="id01338">"Very well," said Craig. "For the sake of argument, let us admit all
that. What did you expect to accomplish by it?"</p>
<p id="id01339">"Why—put an end to it, of course."</p>
<p id="id01340">"But do you think she was going to accept as truth what you told her?<br/>
Would that be natural for one so high-strung?"<br/></p>
<p id="id01341">"Perhaps not—right away. But I supposed she would come to you—as I
see she has, for you know about it. After that, it was only a question
of time. It may have been a heroic remedy, but the disease was
critical."</p>
<p id="id01342">"Suppose," suggested Craig, "that, after all, he told her that he was
there in the Museum, but that he did not get the dagger. And suppose
that she believed it. What then?"</p>
<p id="id01343">Norton looked up quickly. "Did he tell her that?"</p>
<p id="id01344">"I am supposing that he did," repeated Craig, declining to place
himself in a position which might lead to disclosing how he found out.</p>
<p id="id01345">"Then I should say that he was a great deal cleverer than I gave him
credit for being," returned Norton.</p>
<p id="id01346">"Well, it's done now, and can't be undone. Have you found out anything
about the de Moches?"</p>
<p id="id01347">"Not very much, I must admit. Of course, you know I'm not on the best
of terms with them, for some reason or other. But I've been around the
Prince Edward Albert a good deal, and I don't think they've been able
to do much that I haven't some kind of line on. Alfonso seems to be
moping. His professors here tell me that he has been neglecting his
work sadly for the past few days. The Senora and Whitney seem to be as
friendly as ever. I should say that they were going the pace fast, and
it shows on him."</p>
<p id="id01348">I glanced significantly at Kennedy, but he betrayed nothing that might
lead one to suppose he had discovered the cause. Evidently he was not
ready yet to come out into the open and expected further developments
on the poisoned cigarette clue.</p>
<p id="id01349">The telephone rang and Craig took down the receiver.</p>
<p id="id01350">"Yes, this is Kennedy," he answered. "Oh, hello, Lockwood. What's that?
You've been trying to get me all day? I just came in. Why, yes, I can
see you in about half an hour."</p>
<p id="id01351">"I guess I'd better clear out," said Norton with a bitter laugh, as
Kennedy hung up the receiver. "There have been enough crimes committed
without adding another murder to the list."</p>
<p id="id01352">"Keep on watching the de Moches," requested Kennedy as Norton made his
way to the door.</p>
<p id="id01353">"Yes," agreed Norton. "They will bear it—particularly Alfonso. They
are hot-blooded. You never know what they are going to do, and they
keep their own counsel. I might hope that Lockwood would forget; but a
de Moche—never."</p>
<p id="id01354">I cannot say that I envied him very much, for doubtless what he said
was true, though his danger might be mitigated by the fact that the
dagger was no longer in his Museum. Still, it would never have left
Peru, I reflected, if it had not been for him, and there is, even in
the best of us, a smouldering desire for revenge.</p>
<p id="id01355">Lockwood was more than prompt. I had expected that he would burst into
the laboratory prepared to clean things out. Instead he came in as
though nothing at all had happened.</p>
<p id="id01356">"There's no use mincing words, Kennedy," he began. "You know that I
know what has happened. That scoundrel, Norton, has told Inez that you
had shoe-prints of some one who was in the Museum the night of the
robbery and that those shoe-prints correspond with mine. As a matter of
fact, Kennedy, I was there. I was there to get the dagger. But before I
could get it, some one else must have done so. It was gone."</p>
<p id="id01357">I wanted to believe Lockwood. As for Craig he said nothing.</p>
<p id="id01358">"Then, when I did have a chance to get away that night," he continued,<br/>
"I went over to Mendoza's. The rest you know."<br/></p>
<p id="id01359">"You have told Inez that?" asked Kennedy in order to seem properly
surprised.</p>
<p id="id01360">"Yes—and I think she believes me. I can't say. Things are strained
with her. It will take time. I'm not one of those who can take a girl
by main force and make her do what she won't do. I wish I could smooth
things over. Let me see the prints."</p>
<p id="id01361">Kennedy handed them over to him. He looked at them, long and closely,
then handed back the damning evidence against himself.</p>
<p id="id01362">"I know it would be no use to destroy these," he remarked. "In the
first place that would really incriminate me. And in the second I
suppose you have copies."</p>
<p id="id01363">Craig smiled blandly.</p>
<p id="id01364">"But I can tell you," he exclaimed, bringing his fist down on the
laboratory table with a bang, "that before I lose that girl, somebody
will pay for it—and there won't be any mistakes made, either."</p>
<p id="id01365">The scowl on his face and the menacing look in his eye showed that now,
with his back up against the wall, he was not bluffing.</p>
<p id="id01366">He seemed to get little satisfaction out of his visit to us, and in
fact I think he made it more in a spirit of bravado than anything else.</p>
<p id="id01367">Lockwood had scarcely gone before Kennedy pulled out the University
schedule, and ran his finger down it.</p>
<p id="id01368">"Alfonso ought to be at a lecture in the School of Mines," he said
finally, folding up the paper. "I wish you'd go over and see if he is
there, and, if he is, ask him to step into the laboratory."</p>
<p id="id01369">The lecture was in progress all right, but when I peered into the room
it was evident that de Moche was not there. Norton was right. The young
man was neglecting his work. Evidently the repeated rebuffs of Inez had
worked havoc with him.</p>
<p id="id01370">Nor was he at the hotel, as we found out by calling up.</p>
<p id="id01371">There was only one other place that I could think of where he would be
likely to be and that was at the apartment of Inez. Apparently the same
idea occurred to Kennedy, for he suggested going back to our
observation point in the boarding-house and finding out.</p>
<p id="id01372">All the rest of the day we listened through the vocaphone, but without
finding out a thing of interest. Now and then we would try the
detective instrument, the little black disc in the back, but with no
better success. Then we determined to listen in relays, one listening,
while the other went out for dinner.</p>
<p id="id01373">It must have been just a bit after dark that we could hear Inez talking
in a low tone with Juanita.</p>
<p id="id01374">A buzzing noise indicated that there was some one at the hall door.</p>
<p id="id01375">"If it's any one for me," we heard Inez say, "tell them that I will be
out directly. I'm not fit to be seen now."</p>
<p id="id01376">The door was opened and a voice which we could not place asked for the
senorita. A moment later Juanita returned and asked the visitor to be
seated a few moments.</p>
<p id="id01377">It was not long before we were suddenly aware that there was another
person in the room. We could hear whispers. The faithful little
vocaphone even picked them up and shot them down to us.</p>
<p id="id01378">"Is everything all right?" whispered one, a new voice which was
somewhat familiar I thought, but disguised beyond recognition.</p>
<p id="id01379">"Yes. She'll be out in a minute."</p>
<p id="id01380">"Now, remember what I told you. If this thing works you get fifty
dollars more. I'd better put this mask on—damn it!—the slit's torn.
It'll do. I'll hide here as soon as we hear her. That's a pretty nice
private ambulance you have down there. Did you tell the elevator boy
that she had suddenly been taken ill? That's all fixed, then. I've got
the stuff—amyl nitrite—she'll go off like a shot. But we'll have to
work quick. It only keeps her under a few minutes. I can't wear this
mask down and I'm afraid some one will recognize me. Oh, you brought a
beard. Good. I'll give you the signal. There must be no noise. Yes, I
saw the stretcher where you left it in the hall."</p>
<p id="id01381">"All right, Doc," returned the first and unfamiliar voice.</p>
<p id="id01382">It all happened so quickly that we were completely bowled over for the
moment. Who was the man addressed as "Doc"? There was no time to find
out, no time to do anything, apparently, so quickly had the plot been
sprung.</p>
<p id="id01383">I looked at Kennedy, aghast, not knowing what to do in this unexpected
crisis.</p>
<p id="id01384">A moment later we heard a voice, "I'm sorry to have had to keep you
waiting, but what is it that I can do for you?"</p>
<p id="id01385">"Good God!" exclaimed Kennedy. "It is Inez herself!"</p>
<p id="id01386">It was altogether too late to get over there to warn her, perhaps even
to rescue her. What could we do? If we could only shout for help. But
what good would that do, around a corner and so far away?</p>
<p id="id01387">The vocaphone itself!</p>
<p id="id01388">Quickly Kennedy turned another switch, of a rheostat, which accentuated
a whisper to almost a shout.</p>
<p id="id01389">"Don't be alarmed, Senorita," he cried. "This is Kennedy talking. Look
under the bookcase by the window. You will find a cedar box. It is a
detective vocaphone through which I can hear you and which is talking
out to you. I have heard something just there just now—"</p>
<p id="id01390">"Yes, yes. Go on!"</p>
<p id="id01391">"You are threatened. Shout! Shout!"</p>
<p id="id01392">Just then there came a sound of a scuffle and a muffled cry which was
not much above a whisper, as though a strong hand was clapped over her
mouth.</p>
<p id="id01393">What could we do?</p>
<p id="id01394">"Juanita—Juanita—help!—police!" shouted Craig himself through the
vocaphone.</p>
<p id="id01395">An instant later we could hear other screams as Juanita heard and
spread the alarm, not a second too soon.</p>
<p id="id01396">"Come on, Walter," shouted Kennedy dashing out of the room, now that he
was assured the alarm had been given.</p>
<p id="id01397">We hurried around the corner, and into the apartment. One of the
elevators was up, and no one was running the other, but we opened the
gates and Kennedy ran it up by himself.</p>
<p id="id01398">In the Mendoza apartment all was a babel of voices, every one talking
at once.</p>
<p id="id01399">"Did you get them?" Craig asked, looking about.</p>
<p id="id01400">"No, sir," replied the elevator boy. "One of them came in from the
ambulance and told me Miss Mendoza was suddenly taken sick. He rode up
with the stretcher. The other one must have walked up."</p>
<p id="id01401">"Do you know him? Has he ever been here before?"</p>
<p id="id01402">"I can't say, sir. I didn't see him. At least, sir, when I heard the
screams I ran in from the elevator, which the other one told me to wait
with—left the door open. Just as I ran in, they dodged out past me,
jumped into the car and rode down. I guess they must have had the
engine of the ambulance motor running, sir, if they got away without
you seeing them."</p>
<p id="id01403">We were too late to head them from speeding off. But, at least, we had
saved the Senorita. She was terribly upset by the attack, much shaken,
but really all right.</p>
<p id="id01404">"Have you any idea who it could be?" asked Craig as the faithful<br/>
Juanita cared for her.<br/></p>
<p id="id01405">"I don't know the man who was waiting and 'Nita never saw him, either,"
she replied. "The one who jumped out from behind the portieres had on a
mask and a false beard. But I didn't recognize anything about him."</p>
<p id="id01406">Sudden as the attack had been and serious as might have been the
outcome, we could not but feel happy that it had been frustrated.</p>
<p id="id01407">Yet it seemed that some one ought to be delegated to see that such a
thing could not occur again.</p>
<p id="id01408">"We must think up some means of protecting you," soothed Kennedy. "Let
me see, Mr. Lockwood and Mr. Whitney seem to be the closest to you. If
you don't mind I'll call them up. I wonder if you'd object if we had a
little luncheon up here, to-morrow? I have a special reason for asking
it. I want to insure your safety and we may as well meet on common
ground."</p>
<p id="id01409">"There isn't the slightest objection in the world," she replied, as<br/>
Kennedy reached for the telephone.<br/></p>
<p id="id01410">We had some little difficulty in locating both Lockwood and Whitney,
but finally after a time managed to find them and arrange for the
conference on the Senorita's safety for the next day.</p>
<p id="id01411">Outside Kennedy gave instructions to the officer on the beat to watch
the apartment particularly, and there was no reason now to fear a
repetition of the attempt, at least that night.</p>
