There was no anger in his voice as he uttered this threat, nor even, I thought, in his eyes. But what there was was worse.

"But I'm sure you will not make things unpleasant," he concluded. "You will go through the little form I have arranged, if only for curiosity. Just think over it for a moment, while I go to close my little office."

He took the lamp and turned away, but as he reached the angle of the pa.s.sage, there came a sound that checked his steps. I could hear a noise of feet and hurried voices, and then suddenly arose a shout in a voice which seemed to be Plummer's. "Here!" it cried. "Help! This way, Hewitt! Brett!"

I shouted back at the top of my voice, wondering where Plummer was, and what it might all mean. And with that Mayes turned, and I saw that he was about to make for the door I had entered by. I resolved he should not pa.s.s me if I could prevent it, and I sprang up and seized my chair in my left hand, shouting aloud for help as I did so.

Mayes came with a bound, and flung his lighted lamp full at my head. It struck the chair and smashed to a thousand pieces, and in that instant of time Mayes was on me. Plainly he had no weapon, or he would have used it; but I was at disadvantage enough, with my right wrist chained to the wall. I clung with all my might, and endeavoured to swing my enemy round against the wall in order that I might clasp my hands about him, and I shouted my loudest as I did it. But the chair and the broken gla.s.s hampered me, and Mayes was desperate. The agony in my right wrist was unbearable, and just as I was conscious of a rush of approaching feet a heavy blow took me full in the face, and I felt Mayes rush over me while I fell and hung from the wrist.

I had a stunned sense of lights and voices and general confusion, and then I remembered nothing.

III

I came to myself on the floor of a lighted room, with Hewitt's face over mine. My wrist seemed broken, though it was free, there was oil and blood on my clothes, and in my left hand I still gripped a piece of Mayes's coat.

"Stop him!" I cried. "He's gone by the stable! Have they got him?"

"No good, Brett," Hewitt answered soberly. "You did your best, but he's gone, and Peytral after him!"

"Peytral?"

"Yes. He brought his own message to town. But see if you can stand up."

I was well enough able to do that, and, indeed, I had only fainted from the pain of the strain on my wrist. Several policemen were in the room, beside Hewitt and Plummer. Mayes's stronghold was in the hands of his enemies.

Then I suddenly remembered.

"The Admiralty code!" I cried. "It was in the office desk. Have you got it?"

"No," Hewitt answered. "Come, Plummer, up the ladder!"

Little time was lost in forcing Mayes's desk, and there the doc.u.ment was found, grey cover, red tape and all intact. The police were left to make a vigorous search for any possible copy, and the original was handed to Plummer, as chief representative of the law present. He had been trapped precisely as I had been, except that he had been led further, and shut in a cellar as well as fastened by the wrist. Mayes, it seemed, had wasted very little time in attempting to pervert him, and I have no doubt that, whatever fate might have been reserved for me, Plummer would never have left the place alive had it not been for the timely irruption of Hewitt, with Peytral and the police.

In half an hour Peytral returned. He had dashed out in chase of the fugitive, but failed even to see him-lost him wholly in the courts, in fact. For some little while he persevered, but found it useless.

The dirty-whiskered man made no attempt to escape, though there was talk of another man having got away in the confusion by way of the stable roof. The police were left in charge of the place, and we deferred a complete exploration till the next day.

Hewitt's tale was simple enough. He had endued himself in somewhat seedy clothes, and had visited 37 Raven Street, Blackfriars, which he found to be merely a tenement house. It took some time to make inquiries there, with the necessary caution, because of the number of lodgers; and then the inquiries led to nothing. It was an experience common enough in his practice, but none the less an annoying delay, and when he returned to his office he found Mr. Peytral already awaiting him. Peytral described his following of Mayes at much greater length and detail than before, and he and Hewitt had come on to Norbury Row at once and asked news of Mr. Moon.

Mr. Moon's description of the successive disappearances of Plummer and myself, and of our continued absence, so aroused Hewitt's suspicions that he instantly procured help from the nearest station, and approached the door of Mayes's office. A knock being unanswered, the door was instantly broken in. The room was found to be unoccupied, but the ladder was still standing at the open window, by which Mayes had descended to the back premises. Down this ladder Hewitt went, with the police after him. The rest I had seen myself.

"But what," I said, "what is this mystery? Why did Telfer give up the code, and what is the power that Mayes talks of?"

"It is a power," replied Hewitt, "that I have suspected for some time, and now I am quite sure of it. A secret, dangerous and terrible power which I have encountered before, though never before have I known its possibilities carried so far. It is hypnotism!"

"Hypnotism!" I exclaimed. "But can a person be hypnotised against his will?"

"In a sense, in most cases, he cannot. That is the explanation of Mayes's proposals to you to go through a 'form of initiation.' If you had consented, the 'form' would have been a process of hypnotism. Once or twice repeated, and you would have been wholly under his control, so that if he willed it and forbade you, you could tell nothing of what he wished kept secret, and you would have committed any crime he might suggest. Consider poor Jacob Mason! Remember how he struggled to tell what he knew, oppressed by the horror of it, and how it all ended! And remember Henning the clerk, Mayes's tool in that case of bond robbery! What has happened to him? He committed suicide, as you know, immediately after Mayes had left him at the barn. Brett, this power of hypnotism, a power for healing in the hands of a good man, may become a terrible power for evil in the hands of a villain!"

"But Telfer, to-day? He seems to have known nothing of Mayes, and he was not one of his regular creatures-Mayes himself told me so."

"About that I don't know. But I expect we shall find that he has been willingly hypnotised at some time or another, perhaps more than once, by this same scoundrel Mayes. Possibly in one of Mayes's appearances in respectable society, at an evening party, or the like. In a case of that sort the hypnotist may impress a certain formula-a word, a name, or a number-on the subject's mind, by the repet.i.tion of which, at any future time, that same subject may be instantly hypnotised. So that, once having become hypnotised, on any innocent occasion, the subject is in the power of the hypnotist, more or less, ever after. The hypnotist says: 'When I repeat such and such a sentence or number to you in future, you will be hypnotised,' and hypnotised the subject duly is, instantly. Supposing such a case in this matter of Mr. Telfer, it would only be necessary for Mayes to meet him in the corridor, repeat his formula and command the victim to bring out the paper he specified. This done he could similarly order him to forget the whole transaction, and this the victim would do, infallibly."

It is only necessary to say here, parenthetically, that later inquiry proved the truth of Hewitt's supposition. Twice or three times Mr. Telfer had been hypnotised in a friend's chambers, by a plausible tall man whose acquaintance his host had made at some public scientific gathering. And in the end it became possible to identify this man with Mayes.

Mr. Moon, of "The Compa.s.ses," was of great comfort to me that evening. My cuts and bruises were washed in his house, and my inner man revived with his food and drink.

"Allus glad to oblige the p'lice," said Mr. Moon; "allus. 'Cos why? Ain't they the p'lice? Very well then!"

THE ADVENTURE OF CHANNEL MARSH

I

Mayes's stronghold was taken, but Mayes had escaped us once again; the cage was in our hands, but the bird had flown.

Martin Hewitt, however, had his plans, as he was soon to show. The recovery of the Admiralty code was a good stroke, and was a satisfactory ending to an important case; but that, and even the capture of the curious premises behind the Barbican, made but a halting-place in his pursuit of Mayes, and as soon as I was in some degree recovered from my struggle, and the captured place had been hastily searched, the chase was resumed without a moment's delay; and that adventure was entered upon which saw the end of the Red Triangle and its unholy doings-which came terribly near to seeing the end of Hewitt himself, in fact.

I have not described the den near the Barbican with any great particularity, but I have said that the office, accessible from the open street, was only connected with the hidden premises behind-premises, as was afterwards discovered, held under a separate tenancy-by an easily-shifted ladder. It was in these hidden premises, approached by the maze of courts and the stable-yard, that the main evidences of Mayes's way of life were observable. The pa.s.sage where my wrist had been locked to the wall, and the room or cellar in which Plummer had been confined, were the only parts of the lower premises fitted for the detention of prisoners, with the exception of one very low and wholly unlighted cellar, entered by a trapdoor and a very steep flight of brick steps. This place smelt horribly faint and stagnant; but it produced on my mind, both then and when I examined it later, an effect of horror and repulsion more than could be accounted for by the smell alone. Of its history nothing was discovered, and perhaps the feeling (though others experienced it as well as myself) was the effect of mere fancy; but I have never got rid of a conviction that that black cellar, or rather pit-for it was very narrow-had been the instrument of crimes never to be told.

There were one or two rooms sparely furnished-one as a bedroom, a larger room, with a long table, a sofa, and several chairs; and in one of the smaller rooms was found a stove, ladles and crucibles for the melting down of metals-gold or silver. It was in this same room also that the table stood, in the drawers of which were found papers, letters and formulae-things giving more than a hint of the use to which Mayes had put his friendship with Mr. Jacob Mason, for of every possible manner and detail in which science-more particularly the science of chemistry-could aid in the commission of crime, there were notes in these same drawers.

But most of these things were observed in detail later. The thing that set us once more on the trail of Mayes, that very night and that very hour, was found in the isolated office facing the street. It was a cheque-book, quite full of unused cheques.

"This cheque-book," said Hewitt to Inspector Plummer and myself, "was in the drawer below that in which we discovered the Admiralty code. The Eastern Consolidated is the bank, as you see-Upper Holloway branch. Now we must follow this at once, before waiting to search any further. There may be something more important as a clue, or there may not, but at any rate, while we are looking for it we are losing time. This may bring us to him at once."

"You mean that he may have some address in Holloway," suggested Plummer, "and we may get it from the bank?"

"There's that possibility, and another," Hewitt answered. "He has had to bolt without warning or preparation, with nothing but the clothes he ran in-probably very little money. Money he will want at once, and he would rather not wait till the morning to get it; if he can get it at once it will mean thirteen or fourteen hours' start at least. More, he will know very well that this place will be searched, that this cheque-book will be discovered soon enough, and that consequently the bank will be watched. This is what he will do-what he is doing now, very likely. He will knock up the resident manager of that bank and try to get a cheque cashed to-night. I don't think that can be done; in which case he will probably try to make some arrangement to have money sent him. Either way, we must be at the Upper Holloway branch of the Eastern Consolidated Bank as soon as a hansom can get us there."

Thus it was settled, and Hewitt and Plummer went off at once, leaving Plummer's men, with the City police, in charge of the raided premises; leaving some of them also to make inquiries in the neighbourhood. Mr. Victor Peytral had shown himself anxious to accompany Hewitt and Plummer, but had been dissuaded by Hewitt. I guessed that Hewitt feared that some hasty indiscretion on the part of this terribly wronged man might endanger his plans. Peytral, however, seemed tractable enough, and left immediately after them; he had business, he said, which he expected would occupy him for a day or two, and when it was completed he would see us again.

As for myself I only remained long enough to ascertain that the police could find no trace of the direction of Mayes's flight in the immediate neighbourhood. They had little to aid them. He had gone without a hat, and his dress was in some degree disordered by his struggle with me; but the latter defect he might easily have remedied in the courts as he ran, and they could gather no tidings of a hatless man. So I took my way to my office, my wrist growing stiffer and more painful as I went, so that I was not sorry to arrange for another member of the staff to take my duty for the night, and to get to bed a few hours earlier than usual, after the day's fatigue and excitement.

II

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."
