I did so, found the switch and turned on the lights.
It was Denison himself!
For many minutes Kennedy worked over him. I bent down, loosened his collar and shirt, and looked eagerly at his chest for the tell-tale marks of the radium which I felt sure must be there. There was not even a discoloration.
Not a word was said, as Kennedy brought the stupefied little man around.
Denison, pale, shaken, was leaning back now in a big office chair, gasping and holding his head.
Kennedy, before him, reached down into his pocket and handed him the spinthariscope.
"You see that?" he demanded.
Denison looked through the eyepiece.
"Wh--where did you get so much of it?" he asked, a queer look on his face.
"I got that bit of radium from the base of the collar b.u.t.ton of Hartley Haughton," replied Kennedy quietly, "a collar b.u.t.ton which some one intimate with him had subst.i.tuted for his own, bringing that deadly radium with only the minutest protection of a thin strip of metal close to the back of his neck, near the spinal cord and the medulla oblongata which controls blood pressure. That collar b.u.t.ton was worse than the poisoned rings of the Borgias. And there is more radium in the pretty gift of a tortoisesh.e.l.l comb with its paste diamonds which Miss Wallace wore in her hair. Only a fraction of an inch, not enough to cut off the deadly alpha rays, protected the wearers of those articles."
He paused a moment, while surging through my mind came one after another the explanations of the hitherto inexplicable. Denison seemed almost to cringe in the chair, weak already from the fumes.
"Besides," went on Kennedy remorselessly, "when I went in there to drag you out, I saw the safe open. I looked. There was nothing in those pretty platinum tubes, as I suspected. European trust--bah! All the cheap devices of a faker with a confederate in London to send a cablegram--and another in New York to send a threatening letter."
Kennedy extended an accusing forefinger at the man cowering before him.
"This is nothing but a get-rich-quick scheme, Denison. There never was a milligram of radium in the Poor Little Rich Valley, not a milligram here in all the carefully kept reports of Miss Wallace--except what was bought outside by the Corporation with the money it collected from its dupes. Haughton has been fleeced. Miss Wallace, blinded by her loyalty to you--you will always find such a faithful girl in such schemes as yours--has been fooled.
"And how did you repay it? What was cleverer, you said to yourself, than to seem to be robbed of what you never had, to blame it on a bitter rival who never existed? Then to make a.s.surance doubly sure, you planned to disable, perhaps get rid of the come-on whom you had trimmed, and the faithful girl whose eyes you had blinded to your gigantic swindle.
"Denison," concluded Kennedy, as the man drew back, his very face convicting him, "Denison, you are the radium robber--robber in another sense!"
CHAPTER XVI
THE DEAD LINE
Maiden Lane, no less than Wall Street, was deeply interested in the radium case. In fact, it seemed that one case in this section of the city led to another.
Naturally, the Star and the other papers made much of the capture of Denison. Still, I was not prepared for the host of Maiden Lane cases that followed. Many of them were essentially trivial. But one proved to be of extreme importance.
"Professor Kennedy, I have just heard of your radium case, and I--I feel that I can--trust you."
There was a note of appeal in the hesitating voice of the tall, heavily veiled woman whose card had been sent up to us with a nervous "Urgent"
written across its face.
It was very early in the morning, but our visitor was evidently completely unnerved by some news which she had just received and which had sent her posting to see Craig.
Kennedy met her gaze directly with a look that arrested her involuntary effort to avoid it again. She must have read in his eyes more than in his words that she might trust him.
"I--I have a confession to make," she faltered.
"Please sit down, Mrs. Moulton," he said simply. "It is my business to receive confidences--and to keep them."
She sank into, rather than sat down in, the deep leather rocker beside his desk, and now for the first time raised her veil.
Antoinette Moulton was indeed stunning, an exquisite creature with a wonderful charm of slender youth, brightness of eye and brunette radiance.
I knew that she had been on the musical comedy stage and had had a rapid rise to a star part before her marriage to Lynn Moulton, the wealthy lawyer, almost twice her age. I knew also that she had given up the stage, apparently without a regret. Yet there was something strange about the air of secrecy of her visit. Was there a hint in it of a disagreement between the Moultons, I wondered, as I waited while Kennedy rea.s.sured her.
Her distress was so unconcealed that Craig, for the moment, laid aside his ordinary inquisitorial manner. "Tell me just as much or just as little as you choose, Mrs. Moulton," he added tactfully. "I will do my best."
A look almost of grat.i.tude crossed her face.
"When we were married," she began again, "my husband gave me a beautiful diamond necklace. Oh, it must have been worth a hundred thousand dollars easily. It was splendid. Everyone has heard of it. You know, Lynn--er--Mr. Moulton, has always been an enthusiastic collector of jewels."
She paused again and Kennedy nodded rea.s.suringly. I knew the thought in his mind. Moulton had collected one gem that was incomparable with all the hundred thousand dollar necklaces in existence.
"Several months ago." she went on rapidly, still avoiding his eyes and forcing the words from her reluctant lips, "I--oh, I needed money--terribly."
She had risen and faced him, pressing her daintily gloved hands together in a little tremble of emotion which was none the less genuine because she had studied the art of emotion.
"I took the necklace to a jeweler, Herman Schloss, of Maiden Lane, a man with whom my husband had often had dealings and whom I thought I could trust. Under a promise of secrecy he loaned me fifty thousand dollars on it and had an exact replica in paste made by one of his best workmen. This morning, just now, Mr. Schloss telephoned me that his safe had been robbed last night. My necklace is gone!"
She threw out her hands in a wildly appealing gesture.
"And if Lynn finds that the necklace in our wall safe is of paste--as he will find, for he is an expert in diamonds--oh--what shall I do?
Can"t you--can"t you find my necklace?"
Kennedy was following her now eagerly. "You were blackmailed out of the money?" he queried casually, masking his question.
There was a sudden, impulsive drooping of her mouth, an evasion and keen wariness in her eyes. "I can"t see that that has anything to do with the robbery," she answered in a low voice.
"I beg your pardon," corrected Kennedy quickly. "Perhaps not. I"m sorry. Force of habit, I suppose. You don"t know anything more about the robbery?"
"N--no, only that it seems impossible that it could have happened in a place that has the wonderful burglar alarm protection that Mr. Schloss described to me."
"You know him pretty well?"
"Only through this transaction," she replied hastily. "I wish to heaven I had never heard of him."
The telephone rang insistently.
"Mrs. Moulton," said Kennedy, as he returned the receiver to the hook, "it may interest you to know that the burglar alarm company has just called me up about the same case. If I had need of an added incentive, which I hope you will believe I have not, that might furnish it. I will do my best," he repeated.
"Thank you--a thousand times," she cried fervently, and, had I been Craig, I think I should have needed no more thanks than the look she gave him as he accompanied her to the door of our apartment.
