Craig paused while the lawyers whispered again to their clients. Then he continued: “Now three persons in this room had an opportunity to secrete the contents of this deadly tube in the crevices of the metal work of Mrs. Close's bed. One of these persons must have placed an order through a confidential agent in London to purchase the radium from the English Radium Corporation. One of these persons had a compelling motive, something to gain by using this deadly element. The radium in this tube in the casket was secreted, as I have said, in the metal work of Mrs. Close's bed, not in large enough quantities to be immediately fatal, but mixed with dust so as to produce the result more slowly but no less surely, and thus avoid suspicion. At the same time Mrs. Close was persuaded—I will not say by whom—through her natural pride, to take a course of X-ray treatment for a slight defect. That would further serve to divert suspicion. The fact is that a more horrible plot could hardly have been planned or executed. This person sought to ruin her beauty to gain a most selfish and despicable end.”
Again Craig paused to let his words sink into our minds.
“Now I wish to state that anything you gentlemen may say will be used against you. That is why I have asked you to bring your attorneys. You may consult with them, of course, while I am getting ready my next disclosure.”
As Kennedy had developed his points in the case I had been more and more amazed. But I had not failed to notice how keenly Lawrence was following him.
With half a sneer on his astute face, Lawrence drawled: “I cannot see that you have accomplished anything by this rather extraordinary summoning of us to your laboratory. The evidence is just as black against Dr. Gregory as before. You may think you're clever, Kennedy, but on the very statement of facts as you have brought them out there is plenty of circumstantial evidence against Gregory—more than there was before. As for anyone else in the room, I can't see that you have anything on us—unless perhaps this new evidence you speak of may implicate Asche, or Jameson,” he added, including me in a wave of his hand, as if he were already addressing a jury. “It's my opinion that twelve of our peers would be quite as likely to bring in a verdict of guilty against them as against anyone else even remotely connected with this case, except Gregory. No, you'll have to do better than this in your next case, if you expect to maintain that so-called reputation of yours for being a professor of criminal science.”
As for Close, taking his cue from his attorney, he scornfully added: “I came to find out some new evidence against the wretch who wrecked the beauty of my wife. All I've got is a tiresome lecture on X-rays and radium. I suppose what you say is true. Well, it only bears out what I thought before. Gregory treated my wife at home, after he saw the damage his office treatments had done. I guess he was capable of making a complete job out of it—covering up his carelessness by getting rid of the woman who was such a damning piece of evidence against his professional skill.”
Never a shade passed Craig's face as he listened to this tirade. “Excuse me a moment,” was all he said, opening the door to leave the room. “I have just one more fact to disclose. I will be back directly.”
Kennedy was gone several minutes, during which Close and Lawrence fell to whispering behind their hands, with the assurance of those who believed that this was only Kennedy's method of admitting a defeat. Gregory and Asche exchanged a few words similarly, and it was plain that Asche was endeavouring to put a better interpretation on something than Gregory himself dared hope.
As Kennedy re-entered, Close was buttoning up his coat preparatory to leaving, and Lawrence was lighting a fresh cigar.
In his hand Kennedy held a notebook. “My stenographer writes a very legible shorthand; at least I find it so—from long practice, I suppose. As I glance over her notes I find many facts which will interest you later—at the trial. But—ah, here at the end—let me read:
