“Very well, sir.”

“Now, Louis,” remarked Mr Carrados briskly, when the door had closed again, “you have had a good opportunity of studying Parkinson. What is he like?”

“In what way?”

“I mean as a matter of description. I am a blind man—I haven’t seen my servant for twelve years—what idea can you give me of him? I asked you to notice.”

“Five feet nine,” murmured Carrados. “Slightly above the mean.”

“Scarcely noticeably so. Clean-shaven. Medium brown hair. No particularly marked features. Dark eyes. Good teeth.”

“His clothes?”
