“ We were talking about crime detection one night when Annie was in his best form. We sat in my room over our pipes; I was endeavoring to draw him out. “Crime in this country is Easy Money,” he said, and shook his head regretfully. “If a burglary is committed you search for certain characteristics. If a ladder is used to effect an entrance, you lock for A. B. or C. D.; if an entrance is gained by the butler's pantry you arrest E. F. or G. H. Criminals classify themselves in well defined groups, and the police have only to probe one group long enough and deep enough to come upon the criminal.” ”
