I was silent for some time, reflecting on the strange personality of my gifted friend and the singular fitness that he presented for the part he had chosen to play in the drama of social life; but presently my thoughts returned to the peril that overshadowed him, and I came back, once more, to my original question.
"And now, Thorndyke," I said, "that you have penetrated both the motives and the disguise of this villain, what are you going to do? Is he to be put safely under lock and key, or is he to be left in peace and security to plan some other, and perhaps more successful, scheme for your destruction?"
"For the present," replied Thorndyke, "I am going to put these things in a place of safety. To-morrow you shall come with me to the hospital and see me place the ends of the cigar in the custody of Dr. Chandler, who will make an analysis and report on the nature of the poison. After that we shall act in whatever way seems best."
Unsatisfactory as this conclusion appeared, I knew it was useless to raise further objections, and, accordingly, when the cigar with its accompanying papers and wrappings had been deposited in a drawer, we dismissed it, if not from our thoughts, at least from our conversation.
A Startling Discovery
The morning of the trial, so long looked forward to, had at length arrived, and the train of events which it has been my business to chronicle in this narrative was now fast drawing to an end. To me those events had been in many ways of the deepest moment. Not only had they transported me from a life of monotonous drudgery into one charged with novelty and dramatic interest; not only had they introduced me to a renascence of scientific culture and revived under new conditions my intimacy with the comrade of my student days; but, far more momentous than any of these, they had given me the vision—all too fleeting—of happiness untold, with the reality of sorrow and bitter regret that promised to be all too enduring.
Whence it happened that on this morning my thoughts were tinged with a certain greyness. A chapter in my life that had been both bitter and sweet was closing, and already I saw myself once more an Ishmaelite and a wanderer among strangers.
This rather egotistical frame of mind, however, was soon dispelled when I encountered Polton, for the little man was in a veritable twitter of excitement at the prospect of witnessing the clearing up of the mysteries that had so severely tried his curiosity; and even Thorndyke, beneath his habitual calm, showed a trace of expectancy and pleasurable anticipation.
"I have taken the liberty of making certain little arrangements on your behalf," he said, as we sat at breakfast, "of which I hope you will not disapprove. I have written to Mrs. Hornby, who is one of the witnesses, to say that you will meet her at Mr. Lawley's office and escort her and Miss Gibson to the court. Walter Hornby may be with them, and, if he is, you had better leave him, if possible, to come on with Lawley."
"You will not come to the office, then?"
"No. I shall go straight to the court with Anstey. Besides, I am expecting Superintendent Miller from Scotland Yard, who will probably walk down with us."
"I am glad to hear that," I said; "for I have been rather uneasy at the thought of your mixing in the crowd without some kind of protection."
"Well, you see that I am taking precautions against the assaults of the too-ingenious X, and, to tell the truth—and also to commit a flagrant bull—I should never forgive myself if I allowed him to kill me before I had completed Reuben Hornby's defence. Ah, here is Polton—that man is on wires this morning; he has been wandering in and out of the rooms ever since he came, like a cat in a new house."
"It's quite true, sir," said Polton, smiling and unabashed, "so it's no use denying it. I have come to ask what we are going to take with us to the court."
"You will find a box and a portfolio on the table in my room," replied Thorndyke. "We had better also take a microscope and the micrometers, though we are not likely to want them; that is all, I think."
"A box and a portfolio," repeated Polton in a speculative tone. "Yes, sir, I will take them with me." He opened the door and was about to pass out, when, perceiving a visitor ascending the stairs, he turned back.
"Here's Mr. Miller, from Scotland Yard, sir; shall I show him in?"
"Yes, do." He rose from his chair as a tall, military-looking man entered the room and saluted, casting, at the same time, an inquiring glance in my direction.
"Good morning, Doctor," he said briskly. "I got your letter and couldn't make such of it, but I have brought down a couple of plain-clothes men and a uniform man, as you suggested. I understand you want a house watched?"
"Yes, and a man, too. I will give you the particulars presently—that is, if you think you can agree to my conditions."
"That I act entirely on my own account and make no communication to anybody? Well, of course, I would rather you gave me all the facts and let me proceed in the regular way; but if you make conditions I have no choice but to accept them, seeing that you hold the cards."
Perceiving that the matter in hand was of a confidential nature, I thought it best to take my departure, which I accordingly did, as soon as I had ascertained that it wanted yet half-an-hour to the time at which Mrs. Hornby and Juliet were due at the lawyer's office.
Mr. Lawley received me with stiffness that bordered on hostility. He was evidently deeply offended at the subordinate part that he had been compelled to play in the case, and was at no great pains to conceal the fact.
"I am informed," said he, in a frosty tone, when I had explained my mission, "that Mrs. Hornby and Miss Gibson are to meet you here. The arrangement is none of my making; none of the arrangements in this case are of my making. I have been treated throughout with a lack of ceremony and confidence that is positively scandalous. Even now, I—the solicitor for the defence—am completely in the dark as to what defence is contemplated, though I fully expect to be involved in some ridiculous fiasco. I only trust that I may never again be associated with any of your hybrid practitioners. Ne sutor ultra crepidam, sir, is an excellent motto; let the medical cobbler stick to his medical last."
"It remains to be seen what kind of boot he can turn out on the legal last," I retorted.
"That is so," he rejoined; "but I hear Mrs. Hornby's voice in the outer office, and as neither you nor I have any time to waste in idle talk, I suggest that you make your way to the court without delay. I wish you good morning!"
Acting on this very plain hint, I retired to the clerks' office, where I found Mrs. Hornby and Juliet, the former undisguisedly tearful and terrified, and the latter calm, though pale and agitated.
"We had better start at once," I said, when we had exchanged greetings. "Shall we take a cab, or walk?"
"I think we will walk, if you don't mind," said Juliet. "Mrs. Hornby wants to have a few words with you before we go into court. You see, she is one of the witnesses, and she is terrified lest she should say something damaging to Reuben."
"By whom was the subpoena served?" I asked.
"Mr. Lawley sent it," replied Mrs. Hornby, "and I went to see him about it the very next day, but he wouldn't tell me anything—he didn't seem to know what I was wanted for, and he wasn't at all nice—not at all."
"I expect your evidence will relate to the 'Thumbograph,'" I said. "There is really nothing else in connection with the case that you have any knowledge of."
"That is just what Walter said," exclaimed
