“And you thought the rooms were watched?”
“I knew that they were watched.”
“By whom?”
“By my old enemies, Watson. By the charming society whose leader lies in the Reichenbach Fall. You must remember that they knew, and only they knew, that I was still alive. Sooner or later they believed that I should come back to my rooms. They watched them continuously, and this morning they saw me arrive.”
“How do you know?”
“Because I recognized their sentinel when I glanced out of my window. He is a harmless enough fellow, Parker by name, a garroter by trade, and a remarkable performer upon the jew’s-harp. I cared nothing for him. But I cared a great deal for the much more formidable person who was behind him, the bosom friend of Moriarty, the man who dropped the rocks over the cliff, the most cunning and dangerous criminal in London. That is the man who is after me to-night Watson, and that is the man who is quite unaware that we are after him.”
