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 forward 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, 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 your little fairy-tales? We will see if my three years of absence have entirely taken away my power to surprise you.”
