The problem of Cell 13
"With the gas turned on?"
"With the gas turned on. She was asphyxiated."
"Dear me, dear me," exclaimed the scientist. He arose and took up his
hat. "Let's go see what this is all about."
II.
When Professor Van Dusen and Hatch arrived at the apartment house they
had been preceded by the Medical Examiner and the police. Detective
Mallory, whom both knew, was moving about in the apartment where the
girl had been found dead. The body had been removed and a telegram
sent to her employers in New York.
"Too late," said Mallory, as they entered.
"What was it, Mr. Mallory?" asked the scientist.
"Suicide," was the reply. "No question of it. It happened in this
room," and he led the way into the third room of the suite. "The maid,
Miss Regnier, occupied this, and was here alone last night. Mr. and
Mrs. Standing, her employers, have gone to New York for a few days.
She was left alone, and killed herself."
Without further questioning The Thinking Machine went over to the bed,
from which the girl's body had been taken, and, stooping beside it,
picked up a book. It was a novel by "The Duchess." He examined this
critically, then, standing on a chair, he examined the gas jet. This
done, he stepped down and went to the window of the little room.
Finally The Thinking Machine turned to the detective.
"Just how much was the gas turned on?" he asked.
"Turned on full," was the reply.
"Were both the doors of the room closed?"
"Both, yes."
"Any cotton, or cloth, or anything of the sort stuffed in the cracks
of the window?"
"No. It's a tight-fitting window, anyway. Are you trying to make a
mystery out of this?"
"Cracks in the doors stuffed?" The Thinking Machine went on.
"No." There was a smile about the detective's lips.
The Thinking Machine, on his knees, examined the bottom of one of the
doors, that which led into the hall. The lock of this door had been
broken when employees burst into the room. Having satisfied himself
here and at the bottom of the other door, which connected with the
bedroom adjoining, The Thinking Machine again climbed on a chair and
examined the doors at the top.
"Both transoms closed, I suppose?" he asked. "Yes," was the reply.
"You can't make anything but suicide out of it," explained the
detective. "The Medical Examiner has given that as his opinion--and
everything I find indicates it."
"All right," broke in The Thinking Machine abruptly. "Don't let us
keep you."
After awhile Detective Mallory went away. Hatch and the scientist went
down to the office floor, where they saw the manager. He seemed to be
greatly distressed, but was willing to do anything he could in the
matter.
"Is your night engineer perfectly trustworthy?" asked The Thinking
Machine.
"Perfectly," was the reply. "One of the best and most reliable men I
ever met. Alert and wide-awake."
"Can I see him a moment? The night man, I mean?"
"Certainly," was the reply. "He's downstairs. He sleeps there. He's
probably up by this time. He sleeps usually till one o'clock in the
daytime, being up all night."
"Do you supply gas for your tenants?"
"Both gas and electricity are included in the rent of the suites.
Tenants may use one or both."
"And the gas all comes through one meter?"
"Yes, one meter. It's just off the engine room."
"I suppose there's no way of telling just who in the house uses gas?"
"No. Some do and some don't. I don't know."
This was what Hatch had told the scientist. Now together they went to
the basement, and there met the night engineer, Charles Burlingame, a
tall, powerful, clean-cut man, of alert manner and positive speech. He
gazed with a little amusement at the slender, almost childish figure
of The Thinking Machine and the grotesquely large head.
"You are in the engine room or near it all night every night?" began
The Thinking Machine.
"I haven't missed a night in four years," was the reply.
"Anybody ever come here to see you at night?"
"Never. It's against the rules."
"The manager or a hall boy?"
"Never."
"In the last two months?" The Thinking Machine persisted.
"Not in the last two years," was the positive reply. "I go on duty
every night at seven o'clock, and I am on duty until seven in the
morning. I don't believe I've seen anybody in the basement here with
me between those hours for a year at least."
The Thinking Machine was squinting steadily into the eyes of the
engineer, and for a time both were silent. Hatch moved about the
scrupulously clean engine room and nodded to the day engineer, who sat
leaning back against the wall. Directly in front of him was the steam
gauge.
"Have you a fireman?" was The Thinking Machine's next question.
"No. I fire myself," said the night man. "Here's the coal," and he
indicated a bin within half a dozen feet of the mouth of the boiler.
"I don't suppose you ever had occasion to handle the gas meter?"
insisted The Thinking Machine.
"Never touched it in my life," said the other. "I don't know anything
about meters, anyway."
"And you never drop off to sleep at night for a few minutes when you
get lonely? Doze, I mean?"
The engineer grinned good-naturedly.
"Never had any desire to, and besides I wouldn't have the chance," he
explained. "There's a time check here,"--and he indicated it. "I have
to punch that every half hour all night to prove that I have been
awake."
"Dear me, dear me," exclaimed The Thinking Machine, irritably. He went
over and examined the time check--a revolving paper disk with hours
marked on it, made to move by the action of a clock, the face of which
showed in the middle.
"Besides there's the steam gauge to watch," went on the engineer. "No
engineer would dare go to sleep. There might be an explosion."
"Do you know Mr. Weldon Henley?" suddenly asked The Thinking Machine.
"Who?" asked Burlingame.
"Weldon Henley?"
"No-o," was the slow response. "Never heard of him. Who is he?"
"One of the tenants, on the second floor, I think."
"Lord, I don't know any of the tenants. What about him?"
"When does the inspector come here to read the meter?"
"I never saw him. I presume in daytime, eh Bill?" and he turned to the
day engineer.
"Always in daytime--usually about noon," said Bill from his corner.
"Any other entrance to the basement except this way--and you could see
anyone coming here this way I suppose?"
"Sure I could see 'em. There's no other entrance to the cellar except
the coal hole in the sidewalk in front."
"Two big electric lights in front of the building, aren't there?"
"Yes. They go all night."
A slightly puzzled expression crept into the eyes of The Thinking
Machine. Hatch knew from the persistency of the questions that he was
not satisfied; yet he was not able to fathom or to understand all the
queries. In some way they had to do with the possibility of some one
having access to the meter.
"Where do you usually sit at night here?" was the next question.
"Over there where Bill's sitting. I always sit there."
The Thinking Machine crossed the room to Bill, a typical, grimy-handed
man of his class.
"May I sit there a moment?" he asked.
Bill arose lazily, and The Thinking Machine sank down into the chair.
From this point he could see plainly through the opening into the
basement proper--there was no door--the gas meter of enormous
proportions through which all the gas in the house passed. An electric
light in the door made it bright as daylight. The Thinking Machine
noted these things, arose, nodded his thanks to the two men and, still
with the puzzled expression on his face, led the way upstairs. There
the manager was still in his office.
"I presume you examine and know that the time check in the engineer's
room is properly punched every half-hour during the night?" he asked.
"Yes. I examine the dial every day--have them here, in fact, each with
the date on it."
"May I see them?"
Now the manager was puzzled. He produced the cards, one for each day,
and for half an hour The Thinking Machine studied them minutely. At
the end of that time, when he arose and Hatch looked at him
inquiringly, he saw still the perplexed expression.
After urgent solicitation, the manager admitted them to the apartments
of Weldon Henley. Mr. Henley himself had gone to his office in State
Street. Here The Thinking Machine did several things which aroused the
curiosity of the manager, one of which was to minutely study the gas
jets. Then The Thinking Machine opened one of the front windows and
glanced out into the street. Below fifteen feet was the sidewalk;
above was the solid front of the building, broken only by a flagpole
which, properly roped, extended from the hall window of the next floor
above out over the sidewalk a distance of twelve feet or so.
"Ever use that flagpole?" he asked the manager.
"Rarely," said the manager. "On holidays sometimes--Fourth of July and
such times. We have a big flag for it."
From the apartments The Thinking Machine led the way to the hall, up
the stairs and to the flagpole. Leaning out of this window, he looked
down toward the window of the apartments he had just left. Then he
inspected the rope of the flagpole, drawing it through his slender
hands slowly and carefully. At last he picked off a slender thread of
scarlet and examined it.
"Ah," he exclaimed. Then to Hatch: "Let's go, Mr. Hatch. Thank you,"
this last to the manager, who had been a puzzled witness.
Once on the street, side by side with The Thinking Machine, Hatch was
bursting with questions, but he didn't ask them. He knew it would be
useless. At last The Thinking Machine broke the silence.
"That girl, Miss Regnier, _was murdered_," he said suddenly,
positively. "There have been four attempts to murder Henley."
"How?" asked Hatch, startled.
"By a scheme so simple that neither you nor I nor the police have ever
heard of it being employed," was the astonishing reply. "_It is
perfectly horrible in its simplicity_."
"What was it?" Hatch insisted, eagerly.
"It would be futile to discuss that now," was the rejoinder. "There
has been murder. We know how. Now the question is--who? What person
would have a motive to kill Henley?"
III.
There was a pause as they walked on.
"Where are we going?" asked Hatch finally.
"Come up to my place and let's consider this matter a bit further,"
replied The Thinking Machine.
Not another word was spoken by either until half an hour later, in the
small laboratory. For a long time the scientist was thoughtful--deeply
thoughtful. Once he took down a volume from a shelf and Hatch glanced
at the title. It was "Gases: Their Properties." After awhile he
returned this to the shelf and took down another, on which the
reporter caught the title, "Anatomy."
"Now, Mr. Hatch," said The Thinking Machine in his perpetually crabbed
voice, "we have a most remarkable riddle. It gains this remarkable
aspect from its very simplicity. It is not, however, necessary to go
into that now. I will make it clear to you when we know the motives.
"As a general rule, the greatest crimes never come to light because
the greatest criminals, their perpetrators, are too clever to be
caught. Here we have what I might call a great crime committed with a
subtle simplicity that is wholly disarming, and a greater crime even
than this was planned. This was to murder Weldon Henley. The first
thing for you to do is to see Mr. Henley and warn him of his danger.
Asphyxiation will not be attempted again, but there is a possibility
of poison, a pistol shot, a knife, anything almost. As a matter of
fact, he is in great peril.
"Superficially, the death of Miss Regnier, the maid, looks to be
suicide. Instead it is the fruition of a plan which has been tried
