"I wish I could stay and help you," remarked Tresham at length. "But I must be in court at ten. If there"s anything I can do, though, call on me."
"I"m going to find that engine if I have to visit every junk dealer in New York," declared Miss Laidlaw soon after Tresham left.
"That"s about all we can do, yet, I guess," remarked Kennedy, evidently not much worried about the disappearance of the inventor.
Together we three closed up the workshop and started out with a list from a trade publication giving all those who dealt in sc.r.a.p iron and old metal. In fact we spent most of the day going from one to another of the junk shops. I never knew that there were so many dealers in waste.
They seemed to be all over the city and in nearly every section. It was a tremendous job, but we mapped it out so that we worked our way from one section to another.
We had got as far as the Harlem River when we entered one place and looked about while we waited for someone in charge to appear.
I heard a low exclamation from Kennedy, and turned to look in the direction he indicated. There, in a wagon from which the horse had been unhitched, was the heavy base of the engine into which so many dollars had been turned--sold as so much sc.r.a.p!
Kennedy examined it quickly, while I questioned a man who appeared from behind a shed in the rear. It was useless. He could give no clew that we already could not guess. He had just bought it from a man who seemed anxious to get rid of it. His description of the man tallied with Creighton. But that was all. It gave us no chance to trace him.
"Look," exclaimed Kennedy eagerly, bending closer over the motor. "This is one of the neatest perpetual motion frauds I ever heard of."
He had turned the heavy base of the motor upward. One glance left me with little wonder why Creighton had so carefully bolted the machine to the floor. In the base were two rectangular apertures to allow a belt to run over a concealed pulley on the main shaft of the machine in the case. Evidently, when the circuit from the Daniell cells was closed, the pulley, somehow, was thrown into gear. It was loose and the machine began to revolve slowly at first, then faster and with great show of power. The pounding, as Kennedy had surmised, was due to the flywheel not well balanced.
"Well," I remarked, "now that we have found it, I don"t see that it does us much good."
"Only that we understand it," returned Craig. "I left that geophone down there in the room next door which I hired. I think, if Miss Laidlaw will take us down there, I"d like to get it."
He spoke with a sort of easy confidence which I knew was hard to be a.s.sumed in the face of what looked like defeat. Had Craig deliberately let Creighton have a chance to get away, in order that he might convict himself?
In silence, with Miss Laidlaw at the wheel, we went downtown again to the room which Craig had hired next to Creighton"s workshop. As we approached it, he leaned over to Miss Laidlaw.
"Stop around the corner," he asked. "Let"s go in quietly."
We entered our bare little room and Kennedy set to work as though to detach the geophone, while I explained it to our client.
"What"s the matter?" she interrupted in the middle of my explanation, indicating Kennedy.
He had paused and had placed the receivers to his ears. By his expression I knew that the instrument was registering something.
"Someone is in the lower room of the shop next door," he answered, facing us quickly. "If we hurry, we"ll have him cornered."
Miss Laidlaw and I went out and around in front, while Craig dashed through a back door to cut off retreat that way.
"What"s that? Hurry!" exclaimed Miss Laidlaw.
Plainly there was a m.u.f.fled scream of a woman as we entered the street door. I hurried forward. It was the work of only a few seconds to batter down the locked door in the room under Creighton"s old workshop, and as the door gave way, I heard the sound of shattered gla.s.s from the rear which told that Kennedy had heard the scream, too, and had gained an entrance.
Inside I could make out in the half-light a man and a woman. The woman was running toward me, as if for help.
"Mrs. Barry!" gasped Adele Laidlaw.
"He got me here--to kill me!" she cried hysterically. "I am the only one who knows the truth--it was the last day--tonight he would have had the money--and I would have been out of the way. But I"ll expose him--I"ll ruin him. See--he came in from the roof--"
A blinding flash of light greeted us, followed by a scream from Adele Laidlaw, as she ran past us and dropped on her knees beside a body that had fallen with a thud in the flame before a yawning hole in the side wall.
Mrs. Barry ran past me, back again, at almost the same moment. It was a strange sight--these two women glaring at each other over the prostrate figure of the man.
"Here"s the real demon engine," panted Craig, coming up from the back and pointing to an electric motor as well as other apparatus consisting of several series of coils. "The perpetual motion machine was just a fake. It was merely a cover to an attempt to break into the bank vaults by electrolysis of the steel and concrete. Creighton was a dummy, a fiction--to take the blame and disappear when the robbery was discovered."
"Creighton," I repeated, looking at the man on the floor, "a dummy?"
"Oh--he"s dead!" wailed Adele Laidlaw. "He"s dead!"
"Electrocuted by his own machine rather than face disgrace and disbarment," cut in Craig. "No wonder she was in doubt which of the two men fascinated her most."
I moved forward and bent over the contorted form of the lawyer, Tresham, who was wearing the whiskers and iron gray wig of his alter-ego, Creighton.
CHAPTER XXVIII
THE CANCER HOUSE
"You"ve heard of such things as cancer houses, I suppose, Professor Kennedy?"
It was early in the morning and Craig"s client, Myra Moreton, as she introduced herself, had been waiting at the laboratory door in a state of great agitation as we came up. Just because her beautiful face was pale and haggard with worry, she was a pathetic figure, as she stood there, dressed in deep mourning, the tears standing in her eyes merely because we were a little later than usual.
"Well," she hurried on as she dropped into a chair, "that is what they are calling that big house of ours at Norwood--a cancer house, if there is such a thing."
Clearly, Myra Moreton was a victim of nervous prostration. She had asked the question with a hectic eagerness, yet had not waited for an answer.
"Oh," she exclaimed, "you do not, you cannot know what it means to have something like this constantly hanging over you. Think of it--five of us have died in less than five years. It haunts me. Who next. That is all I can think about. Who next?"
Her first agitation had been succeeded by a calmness of despair, almost of fatalism, which was worse for her than letting loose her pent-up emotions.
I had heard of cases of people in whom there was no record of hereditary predisposition to cancer, people apparently in perfect health, who had moved into houses where cancer patients had lived and died and had themselves developed the disease. Though I had, of course, never even remotely experienced such a feeling as she described, I could well fancy what it must be to her.
Kennedy watched her sympathetically. "But why do you come to me?" he asked gently. "Don"t you think a cancer specialist would be more likely to help you?"
"A specialist?" she repeated with a peculiar hopelessness. "Professor Kennedy, five years ago, when my Uncle Frank was attacked by cancer, father was so foolish as to persuade him to consult a specialist whose advertis.e.m.e.nt he saw in the papers, a Dr. Adam Loeb on Forty-second Street here in New York. Specialist! Oh, I"m worried sick every time I have a sore or anything like this on my neck or anywhere else."
She had worked herself from her unnatural calm almost into a state of hysterics as she displayed a little sore on her delicate white throat.
"That?" rea.s.sured Kennedy. "Oh, that may be nothing but a little boil.
But this Dr. Loeb--he must be a quack. No doctor who advertises--"
"Perhaps," she interrupted. "That is what Dr. Goode out at Norwood tells me. But father has faith in him, even has him at the house sometimes. I cannot bear the sight of him. Since I first saw him my uncle, his wife, another aunt, my cousin have died, and then, last week, my--my mother."
Her voice broke, but with a great effort she managed to get herself together. "Now I--I fear that my father may go next. Perhaps it will strike me--or my brother, Lionel--who can tell? Think of it--the whole family wiped out by this terrible thing. Can it be natural, I ask myself? Is there not something back of it?"
"Who is this Dr. Loeb?" asked Kennedy, more for the purpose of aiding her in giving vent to her feelings than anything else.
