 I led the way. The blind man and his secretary followed. Mr. Horace Crail was tall, thin, white-haired. His face was heavily lined, but the lines were not those of care or worry. He wore very dark glasses through which he might not have been able to see, even if he had had his sight. Hugh Gaines, the secretary, was in his late twenties. Surprisingly young and surprisingly handsome for the kind of a job he had. I led them into Mr. Wolfe's office, made the introductions, and sat them down. Well, Mr. Crail, what can I do for you?
