Sir Arthur Conan Doyle: Memoirs of Sherlock Holmes

3. Adventure III: The Stock-Broker's Clerk (continued)

"What now?" whispered Holmes. "Is he giving us the slip?"

"Impossible," answered Pycroft.

"Why so?"

"That door leads into an inner room."

"There is no exit?"

"None."

"Is it furnished?"

"It was empty yesterday."

"Then what on earth can he be doing? There is something which I don't understand in his manner. If ever a man was three parts mad with terror, that man's name is Pinner. What can have put the shivers on him?"

"He suspects that we are detectives," I suggested.

"That's it," cried Pycroft.

Holmes shook his head. "He did not turn pale. He was pale when we entered the room," said he. "It is just possible that--"

His words were interrupted by a sharp rat-tat from the direction of the inner door.

"What the deuce is he knocking at his own door for?" cried the clerk.

Again and much louder cam the rat-tat-tat. We all gazed expectantly at the closed door. Glancing at Holmes, I saw his face turn rigid, and he leaned forward in intense excitement. Then suddenly came a low guggling, gargling sound, and a brisk drumming upon woodwork. Holmes sprang frantically across the room and pushed at the door. It was fastened on the inner side. Following his example, we threw ourselves upon it with all our weight. One hinge snapped, then the other, and down came the door with a crash. Rushing over it, we found ourselves in the inner room. It was empty.
