“Dr. Doyle invariably conceives the end of his story first, and writes up to it. He gets the ‘climax, and his art lies in the ingenious way in which he conceals it from his readers. A story — similar to those which have appeared in these pages — occupies about a week in writing, and the ideas have come at all manner of times—when out walking, cricketing, tricycling, or playing tennis. He works between the hours of breakfast and lunch, and again in the evening from five to eight, writing some three thousand words a day.” –Harry How, Strand Magazine
