Cleek of Scotland Yard by Thomas Hanshew

Hanshews best-known creation was the consulting detective Hamilton Cleek, known as the man of the forty faces for his incredible skill at disguise. The central figure in dozens of short stories that began to appear in 1910 and were subsequently collected in a series of books, Cleek is based in Clarges Street, London, where he is constantly consulted by Inspector Narkom of Scotland Yard. Hamilton Cleek is laughably unrealistic, at least to the modern reader, not only for his ability to impersonate anyone but for his physical derring-do and his frequent melodramatic encounters with Margot, Queen of the Apaches, and her partner-in-crime Merode.
