Henri Bencolin

Henri Bencolin is a fictional detective created by John Dickson Carr. He was Carr's first series detective, appearing in five "locked-room" and "impossible crime" mystery novels in the 1930s, and four short stories that appeared even earlier. In later decades, Carr did not return to the Bencolin character, but instead focused on creating English sleuths such as Dr. Gideon Fell and Sir Henry Merrivale.

Biography
Bencolin is a juge d'instruction (examining magistrate) in the Paris judicial system, and occasionally takes private cases. During World War I, he served as a French spymaster. Bencolin has a forbidding appearance. The narrator of the stories, American writer Jeff Marle, describes him as looking "Satanic", and characterizes his manner with witnesses and suspects as sometimes very harsh. He is sophisticated and cultured, and written to appeal to an American audience that would associate France and French people with sophistication.
