Shows like Mystery!: Campion

Albert Campion --a bespectacled aristocrat of many pseudonyms, who moves amongst the high class as easily as the the crime underworld-- loves detection and adventure. Aided by his burglar-turned-manservant Magersfontein Lugg, and his policeman friend Stanislaus Oates, Campion unravels eight mysteries over the course of the series. Set in the 1930s, the series is based upon the works of English crime writer Margery Allingham.
