allow me to leave your house presently by scrambling over your back garden wall.'
'But what does it all mean?' I asked.
He held out his hand, and I saw in the light of the lamp that two of his knuckles were burst and bleeding. 'It is not an airy nothing, you see,' said he, smiling. 'On the contrary, it is solid enough for a man to break his hand over. Is Mrs. Watson in?'
'She is away upon a visit.'
'Indeed! You are alone?'
'Quite.'
'Then it makes it the easier for me to propose that you should come away with me for a week to the Continent.'
'Where?'
'Oh, anywhere. It's all the same to me.'
There was something very strange in all this. It was not Holmes's nature to take an aimless holiday, and something about his pale, worn face told me that his nerves were at their highest tension.
He saw the question in my eyes, and, putting his fingertips together and his elbows upon his knees, he explained the situation. 'You have probably never heard of Professor Moriarty?' said he.
'Never.'
'Aye, there's the genius and the wonder of the thing!' he cried. 'The man pervades London, and no one has heard of him. That's what puts him on a pinnacle in the records of crime. I tell you, Watson, in all seriousness, that if I could beat that man, if I could free society of him, I should feel that my own career had reached its summit, and I should be prepared to turn to some more placid line in life. Between ourselves, the recent cases in which I have been of assistance to the royal family of Scandinavia, and to the French republic, have left me in such a position that I could continue to live in the quiet fashion which is most congenial to me, and to concentrate my attention upon my chemical researches. But I could not rest, Watson, I could not sit quiet in my chair, if I thought that such a man as Professor Moriarty were walking the streets of London unchallenged.'
'What has he done, then?'
'His career has been an extraordinary one. He is a man of good birth and excellent education, endowed by nature with a phenomenal mathematical faculty. At the age of twenty-one he wrote a treatise upon the Binomial Theorem, which has had a European vogue. On the strength of it he won the Mathematical Chair at one of our smaller universities, and had, to all appearance, a most brilliant career before him. But the man had hereditary tendencies of the most diabolical kind. A criminal strain ran in his blood, which, instead of being modified, was increased and rendered infinitely more dangerous by his extraordinary mental powers. Dark rumors gathered round him in the university town, and eventually he was compelled to resign his chair and to come down to London, where he set up as an army coach. So much is known to the world, but what I am telling you now is what I have myself discovered.
'As you are aware, Watson, there is no one who knows the higher criminal world of London so well as I do. For years past I have continually been conscious of some power behind the malefactor, some deep organizing power which forever stands in the way of the law, and throws its shield over the wrongdoer. Again and again in cases of the most varying sorts—forgery cases, robberies, murders—I have felt the presence of this force, and I have deduced its action in many of those undiscovered crimes in which I have not been personally consulted. For years I have endeavored to break through the veil which shrouded it, and at last the time came when I seized my thread and followed it, until it led me, after a thousand cunning windings, to ex-Professor Moriarty of mathematical celebrity.
'He is the Napoleon of crime, Watson. He is the organizer of half that is evil and of nearly all that is undetected in this great city. He is a genius, a philosopher, an abstract thinker. He has a brain of the first order. He sits motionless, like a spider in the center of its web, but that web has a thousand radiations, and he knows well every quiver of each of them. He does little himself. He only plans. But his agents are numerous and splendidly organized. Is there a crime to be done, a paper to be abstracted, we will say, a house to be rifled, a man to be removed—the word is passed to the Professor, the matter is organized and carried out. The agent may be caught. In that case money is found for his bail or his defense But the central power which uses the agent is never caught —never so much as suspected. This was the organization which I deduced, Watson, and which I devoted my whole energy to exposing and breaking up.
'But the Professor was fenced round with safeguards so cunningly devised that, do what I would, it seemed impossible to get evidence which would convict in a court of law. You know my powers, my dear Watson, and yet at the end of three months I was forced to confess that I had at last met an antagonist who was my intellectual equal. My horror at his crimes was lost in my admiration at his skill. But at last he made a trip—only a little, little trip—but it was more than he could afford when I was so close upon him. I had my chance, and, starting from that point, I have woven my net round him until now it is all ready to close. In three days—that is to say, on Monday next— matters will be ripe, and the Professor, with all the principal members of his gang, will be in the hands of the police. Then will come the greatest criminal trial of the century, the clearing up of over forty mysteries, and the rope for all of them; but if we move at all prematurely, you understand, they may slip out of our hands even at the last moment.
'Now, if I could have done this without the knowledge of Professor Moriarty, all would have been well. But he was too wily for that. He saw every step which I took to draw my toils round him. Again and again he strove to break away, but I as often headed him off. I tell you, my friend, that if a detailed account of that silent contest could be written, it would take its place as the most brilliant bit of thrust-and-parry work in the history of detection. Never have I risen to such a height, and never have I been so hard pressed by an opponent. He cut deep, and yet I just undercut him. This morning the last steps were taken, and three days only were wanted to complete the business. I was sitting in my room thinking the matter over, when the door opened and Professor Moriarty stood before me.
'My nerves are fairly proof, Watson, but I must confess to a start when I saw the very man who had been so much in my thoughts standing there on my threshold. His appearance was quite familiar to me. He is extremely tall and thin, his forehead domes out in a white curve, and his two eyes are deeply sunken in this head. He is clean-shaven, pale, and ascetic-looking, retaining something of the professor in his features. His shoulders are rounded from much study, and his face protrudes forward, and is forever slowly oscillating from side to side in a curiously reptilian fashion. He peered at me with great curiosity in his puckered eyes.
''You have less frontal development that I should have expected,' said he, at last. 'It is a dangerous habit to finger loaded firearms in the pocket of one's dressing-gown.'
'The fact is that upon his entrance I had instantly recognized the extreme personal danger in which I lay. The only conceivable escape for him lay in silencing my tongue. In an instant I had slipped the revolved from the drawer into my pocket, and was covering him through the cloth. At his remark I drew the weapon out and laid it cocked upon the table. He still smiled and blinked, but there was something about his eyes which made me feel very glad that I had it there.
''You evidently don't know me,' said he.
''On the contrary,' I answered, 'I think it is fairly evident that I do. Pray take a chair. I can spare you five minutes if you have anything to say.'
''All that I have to say has already crossed your mind,' said he.
''Then possibly my answer has crossed yours,' I replied.
''You stand fast?'
''Absolutely.'
'He clapped his hand into his pocket, and I raised the pistol from the table. But he merely drew out a memorandum-book in which he had scribbled some dates.
''You crossed my patch on the 4th of January,' said he. 'On the 23d you incommoded me; by the middle of February I was seriously inconvenienced by you; at the end of March I was absolutely hampered in my plans; and now, at the close of April, I find myself placed in such a position through your continual persecution that I am in positive danger of losing my liberty. The situation is becoming an impossible one.'
''Have you any suggestion to make?' I asked.
''You must drop it, Mr. Holmes,' said he, swaying his face about. 'You really must, you know.'
''After Monday,' said I.
