<h2> CHAPTER III. THE ROOM WITH THE SEVEN DOORS </h2>
<p>Mrs. Brewster regarded her surroundings with inward satisfaction. It would
have taken a far more captious critic than the pretty widow to find fault
with the large, high-ceilinged room in which she sat. The handsome carved
Venetian furniture, the rich hangings and valuable paintings on the walls
gave evidence of Colonel McIntyre's artistic taste and appreciation of the
beautiful. Mrs. Brewster had never failed, during her visit to the
McIntyre twins, to examine the rare curios in the carved cabinets and the
tapestries on the walls, but that afternoon, with one eye on the clock and
the other on her embroidery, she sat waiting in growing impatience for the
interruption she anticipated.</p>
<p>The hands of the clock had passed the hour of five before the buzz of a
distant bell brought her to her feet. Hurrying to the window she peeped
between the curtains in time to see a stylish roadster electric glide down
the driveway leading from the McIntyre residence and stop at the curb. As
she turned to go back to her chair Dr. Stone was ushered into the library
by the footman. Mrs. Brewster welcomed her cousin with frank relief.</p>
<p>"I have waited so impatiently for you," she confessed, making room for him
to sit on the sofa by her side.</p>
<p>"I was detained, Margaret." Stone's voice was not over-cordial; three
imperative telephone calls from her, coming at a moment when he had been
engaged with a serious case in his office, had provoked him. "Do you wish
to see me professionally?"</p>
<p>"Indeed, I don't." She laughed frankly. "I am the picture of health."</p>
<p>Stone, observing her fine coloring and clear eyes, silently agreed with
her. The widow made a charming picture in her modish tea-gown, and the
physician, watching her with an appraising eye, acknowledged the beauty
which had captivated all Washington. Mrs. Brewster had carried her honors
tactfully, a fact which had gained her popularity even among the dowagers
and match-making mothers who take an active part in Washington's social
season.</p>
<p>"Then, Margaret, what do you wish to see me about?" Stone asked, after
waiting without result for her to continue speaking.</p>
<p>She laughed softly. "You are the most practical of men," she said. "It
would not have been so difficult to find a companion anxious to spend the
whole afternoon with me for my sake alone."</p>
<p>"Colonel McIntyre, for instance?" he teased, and laughed amusedly at her
heightened color. "Have a care, Margaret; McIntyre's flirtations are all
very well, but he is the type of man to be deadly in earnest when once he
falls in love."</p>
<p>"Thanks for your warning," Mrs. Brewster smiled, then grew serious. "I
sent for you to ask about Jimmie Turnbull's death this morning. Barbara
told me you accompanied them to the police court."</p>
<p>"Yes. Why weren't you with the girls?"</p>
<p>"Because I was told nothing of their trip to the police court until they
had returned," she replied. "How horribly tragic the whole affair is!" And
a shiver she could not suppress crept down her spine.</p>
<p>"It is," agreed Stone. "What possessed Jimmie Turnbull to play so mad a
trick?"</p>
<p>"His wager with Barbara."</p>
<p>Stone leaned a little nearer. "Have you learned the nature of that wager?"
he asked, lowering his voice.</p>
<p>"No. Babs was in so hysterical a condition when she returned from the
police court that she gave a very incoherent account of the whole affair,
and she has kept her room ever since luncheon," explained Mrs. Brewster.</p>
<p>Stone looked puzzled. "I understood that Jimmie was attentive to Helen
McIntyre and not to Barbara," he said. "But upon my word, Barbara appeared
more overcome by Jimmie's death than Helen."</p>
<p>Mrs. Brewster did not reply at once; instead, she glanced carefully
around. The room was generally the rallying place of the McIntyres. It
stretched across almost the entire width of the house; the diamond-paned
and recessed windows gave it a medieval air in keeping with its antique
furniture, and the seven doors opening from it led, respectively, to the
large dining room beyond, a morning room, billiard room, the front and
back halls, and the Italian loggia which over-looked the stretch of ground
between the McIntyre residence and its neighbor on the north. Apparently,
she and Dr. Stone had the room to themselves.</p>
<p>"I cannot answer your question with positiveness," she stated. "Frankly,
Jimmie appeared impartial in his attentions to the twins. When he wasn't
with Barbara he was with Helen, and vice versa."</p>
<p>Stone gazed at her in some perplexity. "Are you aware that Helen stated at
the police court this morning that she was Turnbull's fiancee?"</p>
<p>"What!" Mrs. Brewster actually bounced in her seat. "You—you astound
me!"</p>
<p>"I was a bit surprised myself," acknowledged the physician. "I thought
Rochester—however, that is neither here nor there. Helen not only
announced she was Jimmie's fiancee but as such demanded that a post-mortem
examination be held to determine the cause of his death."</p>
<p>Mrs. Brewster's pretty color faded and the glance she turned on her cousin
was sharp. "Why should Helen suspect foul play?" she demanded. "For that
is what her request hinted."</p>
<p>"True." Stone pulled his beard absentmindedly. "Ah, here is Colonel
McIntyre," he exclaimed as the portieres before the hall door parted and a
tall man strode into the library.</p>
<p>McIntyre was a favorite with the old physician, and he welcomed his
arrival with warmth. Exchanging a word of greeting with Mrs. Brewster,
McIntyre drew up a chair and dropped into it.</p>
<p>"I called at your office, doctor," he said. "Went there at once on
learning the shocking news about poor Turnbull. Why in the world didn't he
announce who he was when my daughter had him arrested as a burglar? He
must have realized that prolonged excitement was bad for his weak heart."</p>
<p>Mrs. Brewster, who had settled herself more comfortably in her corner of
the sofa on McIntyre's arrival, answered his remark.</p>
<p>"I only knew Jimmie superficially," she said, "but he had one
distinguishing trait patent to all, his inordinate fondness for practical
jokes. Probably the predicament he found himself in was highly to his
taste—until his heart failed."</p>
<p>Her voice, slightly raised, carried across the room and reached the ears
of a tall, slender girl who had stood hesitating on the threshold of the
dining worn door on beholding the group by the sofa. All hesitation
vanished, however, as the meaning of Mrs. Brewster's remark dawned on her,
and she walked over to the sofa.</p>
<p>"You are very unjust, Margaret," she stated, and at sound of her low
triante voice McIntyre whirled around and frowned slightly. "Jimmie was
thinking of the predicament of others, not of himself."</p>
<p>"What do you mean, Helen?" her father demanded.</p>
<p>"Why, how could Jimmie reveal his identity in court without involving us?"
she asked. "Good afternoon, doctor," recollecting her manners, and her
attention thus diverted, she missed the sudden questioning look which Mrs.
Brewster and her father exchanged. "No," she continued, "Jimmie sacrificed
himself for others."</p>
<p>"By becoming a burglar." McIntyre laughed shortly. "Don't talk arrant
nonsense, Helen."</p>
<p>The girl flushed at his tone, and Dr. Stone, an interested onlooker,
marveled at the fleeting flash of disdain which lighted her dark eyes.
Stone's interest grew. The McIntyre family had always been particularly
congenial, and the devotion of Colonel McIntyre (left a widower when the
twins were in short frocks) to his daughters had been commented on
frequently by their wide circle of friends in Washington and by
acquaintances made in their travels abroad.</p>
<p>Colonel McIntyre had married when quite a young man. Frugality and
industry and a brilliant mind had reaped their reward, and, wiser than the
majority of Americans, he retired early from business and devoted himself
to a life of leisure and the education of his daughters. Their debut the
previous autumn had been one of the social events of the Washington
season, and the instant popularity the girls had attained proved a source
of pride to Colonel McIntyre. His chief pleasure consisted in gratifying
their every whim, and Dr. Stone, knowing the family as he did, wondered at
the faintly discernible air of constraint in the girl's manner. Usually
frank to a sometimes embarrassing degree, she appeared to some
disadvantage as she sat gazing moodily at the tips of her patent-leather
pumps. Dr. Stone's attention shifted to Colonel McIntyre and lastly to the
pretty widow at his elbow. Had Dame Rumor spoken truly in the report,
widely circulated, that the colonel had fallen a victim to the charms of
Margaret Brewster, his daughters' guest? If so, it might account for the
young girl's manner—however devoted McIntyre's daughters might be to
Mrs. Brewster as a friend and companion, they might resent having so young
a woman for their step-mother.</p>
<p>Not receiving any reply to his remarks, McIntyre was about to address his
daughter again when she spoke.</p>
<p>"Jimmie will be justified," she declared stoutly. "Has the coroner held
the autopsy yet, Dr. Stone?"</p>
<p>"Autopsy!" McIntyre spoke with sharp abruptness. "I thought it was clearly
established that Jimmie died from angina pectoris?"</p>
<p>"It is so believed," responded Stone. His mystification was growing; had
not Helen informed her father of the scene which had transpired at the
police court, and of her request to the coroner? "I understand the
post-mortem examination will be made this afternoon, Helen."</p>
<p>A heavy paper knife, nicely balanced between McIntyre's well manicured
fingers, dropped to the floor as a step sounded behind him and the butler,
Grimes, stopped by his side.</p>
<p>"Mr. Rochester just telephoned that his partner, Mr. Harry Kent, is out of
town, Miss"—bowing to the silent girl. Grimes always contented
himself with addressing his "young ladies" by the simple prefix "Miss,"
and never added their given names, because, as he expressed it, "them
twins are alike as two peas, and which is which, I dunno." Considering
himself one of the family from his long service with Colonel McIntyre, he
kept a watchful eye on the twins, but their pranks in childhood had often
exasperated him into giving notice, which he generally found it convenient
to forget when the first of a new month came around.</p>
<p>"Mr. Kent will be back to-morrow," added the butler, as silence followed
the delivery of his message. "Mr. Rochester wishes to know if he can
transact any business for you."</p>
<p>"Please thank him and say no." The girl's color rose as she caught her
father's disapproving look. The colonel waited until the butler had
disappeared before addressing her.</p>
<p>"Why did you send for Harry Kent?" he questioned. "You know I do not
approve of his attentions to Barbara. Rochester is well enough—"</p>
<p>"Speaking of Rochester"—Mrs. Brewster saw the gathering storm clouds
in the girl's expressive eyes, and broke hastily into the conversation. "I
see by the paper, Cousin Amos"—she turned so as to face Dr. Stone—
"that Mr. Rochester declared positively that Jimmie Turnbull died from
angina pectoris."</p>
<p>"What's Philip's opinion worth?" The young girl smiled disdainfully.
"Philip seems to think that having shared an apartment with Jimmie, gives
him intimate knowledge of Jimmie's health. Philip is not a medical man."</p>
<p>"No," acknowledged her father. "But here is a medical man who was on the
spot when Jimmie died. What's your opinion, Stone?"</p>
<p>Stone, suddenly conscious of the keen attention of his companions, spoke
slowly as was his wont when making a serious statement.</p>
<p>"Rochester's contention that Jimmie died from angina pectoris would seem
borne out by what transpired," he said. "Undoubtedly Jimmie felt an attack
coming on and used the customary remedy to relieve it—"</p>
<p>"And what was that remedy?" questioned Mrs. Brewster swiftly.</p>
<p>"Amyl nitrite." Stone spoke with decision. "I could detect its presence by
the fruity, pleasant odor which always accompanies the drug's use."</p>
<p>"Ah!" The exclamation slipped from Mrs. Brewster. "Is the drug
administered in water?"</p>
<p>"No, it is inhaled—take care, you have dropped your handkerchief."
Stone pulled himself up short in his speech, and bent over but the young
girl was too quick for him, and stooped first to pick up her handkerchief.</p>
<p>As she raised her head Stone caught sight of the tiny mole under the lobe
of her left ear. It was the one mark which distinguished Barbara from her
twin sister. Colonel McIntyre had addressed his daughter as Helen, and she
had not undeceived him—Why? The perplexed physician gave up the
problem.</p>
<p>"The drug," he went on to explain, "amyl nitrite comes in pearl capsules
and is crushed in a handkerchief and the fumes inhaled."</p>
<p>Mrs. Brewster leaned forward suddenly. "Would that cause death?" she
asked.</p>
<p>Stone shook his head in denial. "Not the customary dose of three minims,"
he answered, and turning, found that Barbara had stolen from the room.</p>
