the latter part of these directions I was somewhat disposed to boggle, remembering my worthy teacher's threat to put me somewhere out of harm's way. But Thorndyke was a difficult man to disobey. Suave and persuasive as his manners were, he had a certain final and compelling way with him that silenced objections and produced a sort of frictionless obedience without any sense of compulsion. Hence, notwithstanding a slight tendency to bluster and tell myself that I would see him hanged before I would submit to being mollycoddled like an idiot, I found myself, presently, walking down the Grove in a buff overcoat and a grey felt hat, carrying a green canvas suit-case in which were packed the necessaries for a brief stay away from home, and bearing in my pocket the incriminating letter.
I walked slowly as far as the Junction Road in order to give any pursuer a fair opportunity to take up the chase and to make the necessary observations on my tasteful turn-out. At the Junction I waited for a tram and carefully abstained from staring about in a manner which would have embarrassed any person who might wish unobserved to share the conveyance with me; and from the terminus at Euston Road I proceeded in leisurely fashion on foot, still resisting the temptation to look about and see if I had picked up a companion by the way.
Salter's Club was domiciled in a typical West End house situated in a quiet street of similar houses, graced at one end by a cabstand. I timed my arrival with such accuracy that a neighbouring church-clock struck one as I ascended the steps; and on my entering the hall, I was met by an elderly man in a quiet livery who seemed to expect me, for, when I mentioned Thorndyke's name, he asked, "Dr. Jardine, sir?" and, hardly waiting for my reply, showed me to the cloak-room. "Dr. Thorndyke," said he, "will be with you in a few minutes. When you have washed, I will show you to the dining room where he wished you to wait for him."
I was just a little surprised at even this short delay, for Thorndyke was the soul of punctuality. However, I had not to wait long. I had been sitting less than three minutes at a small table laid for two in the deep bay window, scanning the street through the wire-gauze blinds, when he arrived. "I needn't apologize, I suppose, Jardine," he said, shaking my hand heartily. "You will have guessed why I have kept you waiting."
"You flatter me, sir," I replied with a slight grin. "I haven't your powers of instantaneous deduction."
"You hardly needed them," he retorted. "Of course I was watching your approach and observing the corner by which you entered the street to see who came after you."
"Did anyone come after me?"
"Several persons. I examined them all very carefully with a prism binocular that magnifies twelve times linear, and an assistant is now at the same window—the one over this—following the fortunes of those persons with the same excellent glass."
"Did you spot anyone in particular as looking a likely person?"
"Yes. The second man who came after you seemed to be sauntering in a rather unpurposive fashion and looking a little obtrusively unconcerned. I noticed, too, that he was carrying an umbrella in his left hand. But we needn't concern ourselves. If anyone is shadowing you we are certain to see him. He must expose himself to view from time to time, for he can't afford to lose sight of our doorway for more than a few seconds, and there is practically no cover in this street."
"He might hide in a doorway," I suggested.
"Oh, might he! These are all clubs in this street. He'd very soon have the servants out wanting to know his business. No; he'll have to keep on the move and he'll have to keep mostly in sight of this house. And meanwhile we are going to take our lunch at our leisure and have a little talk to while away the time."
The lunch was on a scale that my youthful appetite approved strongly, though the number of courses and irrelevant, time-consuming kickshaws struck me as rather unusual. And I never saw a man eat so slowly and delay a meal so much as Thorndyke did on that occasion. I believe that it took him fully twenty minutes to consume a fried sole; and even then he created a further delay by drawing my attention to the skeleton on his plate as an illustration of inherited deformity adjusted to special environmental conditions. But all the time, whether eating or talking, I noticed that his eye continually travelled up and down the stretch of street that was visible through the wire blinds. "You haven't told me why you sent for me, sir," I said, after waiting patiently for him to open the subject.
"I dare say you have guessed," he replied;" but we may as well thrash the matter out now. You realize that you are running an enormous and unnecessary risk by going abroad with this man at your heels?"
"Well, I don't suppose he is following me about from sheer affection."
"No. I thought it possible that he might be a plain-clothes policeman, but I have ascertained that he is not. Who he is we don't know, but we have the strongest reasons for suspecting his intentions. There have been three very determined attempts on your life. They were all made with such remarkable caution and foresight that, though they failed, practically no traces have been left. Those attempts imply a strong motive, though to us, an unknown one; and that motive, presumably, still exists. Your enemy may well be getting desperate, and may be prepared to take greater risks to get rid of you; and if he is, the chances are that he will succeed sooner or later. Murder isn't very difficult to a cool-headed man who means business."
"Then what do you propose, sir?"
"I propose that you disappear from your ordinary surroundings and come and stay, for a time, at my chambers in the Temple."
This was no more than I had expected, but my jaw dropped considerably, notwithstanding. "It's awfully good of you, sir," I stammered—and so, to be sure, it was—" but don't you think it would be simpler to turn the tables on this Johnnie and shadow him?"
"An excellent idea, Jardine, and one, I may say, that I am acting on at this moment. But there isn't so much in it as you seem to think. Supposing we identify this man and even run him to earth? What then? We have nothing against him. We know of no crime that has been committed. We may suspect that the man whom you saw at Hampstead had been murdered. But we can't prove it. We can't produce the body or even prove that the man was dead. And we couldn't connect this person with the affair because nobody was known to be connected with it. I should like to know who this man is, but I don't want to put him on his guard; and above all, I can't agree to your going about as a sort of live-bait to enable us to locate him. By the way, that man on the opposite side of the street is the one whom I selected as being probably your attendant. Apparently I was right, as this is the third time he has passed. Do you recognize him?"
I looked attentively at the uncharacteristic figure on the farther side of the street, but could find nothing familiar in his appearance. "No," I replied; "he doesn't look to me like the same man. He is dressed differently—but that's nothing, as he has been dressed differently on each occasion—and that torpedo beard and full moustache are quite unlike, though there's nothing in that either; but the man looks different altogether—distinctly taller, for instance."
Thorndyke chuckled. "Good," said he. "Now look at his feet, as he passes opposite. Did you ever see an instep set at that angle to the sole? And does not your anatomical conscience cry out at a foot of that thickness?"
"Yes, by Jove!" I exclaimed; "there's room for a double row of metatarsals. It is a fake of some kind, I suppose?"
"Cork 'raisers' inside high-heeled boots. Through the glasses I could see that the boots gaped considerably at the instep, as they will when there is a pad inside as well as a foot. But you notice, also, that the man is dressed for height. He has a tall hat, a long coat, and his shoulders are obviously raised by padding. I think there is very little doubt that he is our man."
"It must be a dull job," I remarked, "hanging about by the hour to see a man come out
