ロンドン聖地巡礼「シャーロック・ホームズ」（準備編）その2

"You never were in it?"
"No, Watson, I never was in it. My note to you was absolutely genuine. I had little doubt that I had come to the end of my career when I perceived the somewhat sinister figure of the late Professor Moriarty standing upon the narrow pathway which led to safety. I read an inexorable purpose in his grey eyes. I exchanged some remarks with him, therefore, and obtained his courteous permission to write the short note which you afterwards received. I left it with my cigarette-box and my stick and I walked along the pathway, Moriarty still at my heels. When I reached the end I stood at bay. He drew no weapon, but he rushed at me and threw his long arms around me. He knew that his own game was up, and was only anxious to revenge himself upon me. We tottered together upon the brink of the fall. I have some knowledge, however, of baritsu, or the Japanese system of wrestling, which has more than once been very useful to me. I slipped through his grip, and he with a horrible scream kicked madly for a few seconds and clawed the air with both his hands. But for all his efforts he could not get his balance, and over he went. With my face over the brink I saw him fall for a long way. Then he struck a rock, bounded off, and splashed into the water."

I had imagined that we were bound for Baker Street, but Holmes stopped the cab at the corner of Cavendish Square（5）. I observed that as he stepped out he gave a most searching glance to right and left, and at every subsequent street corner he took the utmost pains to assure that he was not followed.
Our route was certainly a singular one. Holmes's knowledge of the byways of London was extraordinary, and on this occasion he passed rapidly, and with an assured step, through a network of mews and stables the very existence of which I had never known. We emerged at last into a small road, lined with old, gloomy houses, which led us into Manchester Street, and so to Blandford Street（13）. Here he turned swiftly down a narrow passage, passed through a wooden gate into a deserted yard, and then opened with a key the back door of a house. We entered together and he closed it behind us.
The place was pitch-dark, but it was evident to me that it was an empty house. Our feet creaked and crackled over the bare planking, and my outstretched hand touched a wall from which the paper was hanging in ribbons. Holmes's cold, thin fingers closed round my wrist and led me forwards down a long hall, until I dimly saw the murky fanlight over the door. Here Holmes turned suddenly to the right, and we found ourselves in a large, square, empty room, heavily shadowed in the corners, but faintly lit in the centre from the lights of the street beyond. There was no lamp near and the window was thick with dust, so that we could only just discern each other's figures within. My companion put his hand upon my shoulder and his lips close to my ear.
"Do you know where we are?" he whispered.
"Surely that is Baker Street," I answered, staring through the dim window.
"Exactly. We are in Camden House（15）, which stands opposite to our own old quarters."
"But why are we here?"
"Because it commands so excellent a view of that picturesque pile. Might I trouble you, my dear Watson, to draw a little nearer to the window, taking every precaution not to show yourself, and then to look up at our old rooms -the starting-point of so many of our little adventures? We will see if my three years of absence have entirely taken away my power to surprise you."
