Going to bed uncommonly soon I woke correspondingly early in the morning; but I was no earlier than Hewitt, who was at my door, in fact, ere my breakfast was well begun.

"Well," I asked eagerly, almost before my friend had entered, "have you got him at last?"

"Not yet," Hewitt answered. "But he did exactly as I had expected. Plummer and I knocked up the bank manager, who lives over the premises at the Upper Holloway branch. He was a very decent fellow—rather young for the post—but he was naturally a bit surprised, possibly irritated, at being bothered by one and another after office hours. I showed him the cheque-book, and asked him if it belonged to any customer of his.

"'Why, yes,' he said, examining the numbers, 'I remember this because it is the first of a new series, and we issued it the day before yesterday to a new customer. Where did you get it?'

"'We are very anxious to see that customer,' I said. 'Has he been here this evening?'

"The manager seemed a trifle surprised, but answered readily enough. 'Yes,' he said, 'he was here not an hour ago.'

"'Wanting to draw money?' I asked. But that the manager wouldn't tell me, of course. So that it was necessary for Plummer to step in and reveal the facts that this was a police matter, and that he was a detective-inspector. That made some difference. The manager told us that our man had opened an account at the bank only two days before; and I'd like you to guess what name he had opened it under."

"Not Myatt?" I said. "After the chase——"

"No, not Myatt."

"Catherton Hunt?"

"No, nor Catherton Hunt. He had opened it in the name of Mayes!"

"What! his actual name?"

"His actual original name, according to Peytral. The account was transferred, it would seem, from another bank; and I have an idea we may find that he has been shifting his money about from one bank to another as safety suggested, using his real name with it. You remember we could find no trace of a banking account when the police raided and ransacked Calton Lodge after Mason was killed? Quite probably he has had small current accounts in other names at various times to aid in his schemes, but his main account has always stood in his real name; and by that, you see, we get some confirmation of Peytral's story. Well, as I say, the account was opened in the name of Mayes, and the cheque-book was issued which we discovered last night. The Upper Holloway branch saw no more of its customer till yesterday evening, long after hours, when he drove up in a hansom."

"Oh," I said, "in a hansom, was it? The men left behind could get no news of him."

"Yes, we ascertained that last night; we called back, of course, the last thing. I expect he got the first cab visible and drove off to a hatter's a fair distance away, and then on to the bank. At any rate, he knocked up the manager and told him that he had a sudden need for money that very night; could he have some?

"The manager told him it would be impossible. Even if he had been willing to do it, against all regulations, it would still be impossible. For the strong-room and every cash receptacle in it was locked with two separate locks with different keys, and though he had one of these keys himself, it was useless without the other, which was in the possession of his second in command, who lived some distance out of London. This course is the usual precaution adopted in branch banks of this sort; opening and closing, morning and evening, have to be done by chief and assistant together. And I tell you, Brett, I believe that it was only the being informed of this fact that prevented Mayes from trying some of his hypnotic tricks on the bank manager; in which case there would have been a big bank robbery—perhaps something worse in addition."

"Murder?"

"Murder with a tourniquet, perhaps—perhaps with some other weapon; but, at any rate, probably with the Red Triangle. You know, of course—indeed I told you, I think—that in most cases—not all—it is necessary to get the subject's consent to the first exercise of hypnotism on him. I told you also it is possible for the practised hypnotist, while the subject is under the influence of the first experiment, to suggest to him a certain word or formula, or even a silent sign, which shall bring him under the influence at any other time, whenever the hypnotist chooses to repeat it—just as must have been done with Mr. Telfer, in the case of the Admiralty code. The first suggestion would not be the difficult thing it might seem—it would only require a little time and persuasion. Nothing would be said about hypnotism, of course; perhaps something about a little physical experiment, or the like, and then in a moment or two the subject would be in this creature's power for ever. Remember the little 'ceremony of initiation' that the scoundrel attempted to persuade you to submit to! That meant hypnotism—perhaps death.

"But this is mere speculation. Mayes found that the keys on the premises were not enough to release his money, even if the strict rules of the bank had permitted the cashing of a cheque out of hours. But the manager suggested that perhaps some neighbouring tradesman would exchange cash for a cheque, and, with the view of obliging the new customer, went with him as far as the shop of Mr. Isaac Trenaman, a grocer and cheesemonger with a rather large shop at the corner of the road. Mr. Trenaman, introduced and assured by the manager, was willing to give as much cash as he could find in the till against Mr. Mayes's cheque, and did so to the extent of twenty-seven pounds, a cheque for which sum was duly drawn on one of the tradesman's own cheque forms, and left with him. This done, the bank's new customer took himself off, with thanks and apologies; carrying with him, however, two blank cheque forms from Mr. Trenaman's book, the pennies for which he punctiliously paid over the counter. Having no cheque forms with him, he explained, he might find them useful if he could come across some friend who could provide the cash he wished to use that night. And having completed this business so far, this charming new customer of the bank made off into the night."

"And is that all you know of his movements?"

"Yes, as yet. He seems to have made no very definite excuse to the manager for wanting the money in such a hurry—just said something had occurred which made cash necessary, and was very polite and apologetic, generally. The manager formed a notion that it must be for some gambling purpose—he fancied that Mayes said something distantly alluding to that, but wasn't sure."

"Did you ask about the address given to the bank?"

"Of course; but there we gained nothing. The manager couldn't remember it exactly, and the books, of course, were locked up. But we know it already—for what the manager could remember was that it was an office address, and somewhere near Barbican! So that we are back at the Barbican den again, where I am going now, with Plummer, to give a day to a minute investigation of the whole place. Meanwhile a watch is being set at the bank in Holloway."

"Do you expect him back there, then?"

"Hardly. You see he knows that by this time we must have found his cheque-book, and will be on the watch. But there is just a chance—a very remote one—that he may send a message; perhaps send somebody to cash a cheque. Though I don't expect it, for he is no fool—he is, indeed, a sort of genius—and that would be a mistake, I think. Still, he is bold, and that is where his money is, and he may make a dash at it. So a couple of Plummer's men are to be waiting there, this morning, in the manager's office, and if anybody comes from Mayes he will be detained. Perhaps you would like to be with them? You can't be of much use with me, and the job will be dull. But there you may have a chance of excitement, and you will be useful to come and report if anything does happen. Why, you may even bag Mayes himself!"

"Of course—I'll go anywhere you please. They told you last night, I suppose, that Peytral had business, and had gone off?"

"Yes, and I'm not sorry. He is too dangerous a man to have about us, with his hot blood and the terrible injuries he keeps in memory. As likely as not, if we get Mayes, we should next have to collar Peytral for shooting him, or something. So I'm not sorry he is out of it for a bit. But can you start now? Plummer is in my office and the two men are in a cab outside. The bank opens at nine, and that is in Upper Holloway."

I seized my hat and made ready.

"You should keep your eyes open," Hewitt hinted, "before you get to the bank and when you leave, as well as while you're there. Do you remember how poor Mason was watched? Well, there is probably some watching going on now. Last night, on our way to the bank and back, I believe Plummer and I were watched pretty closely."
