The Beiderbecke Affair by Alan Plater

Two unconventional schoolteachers in northern England — a laconic, jazz-loving man and his idealistic, politically minded colleague — accidentally become amateur sleuths when a routine encounter uncovers missing documents and a small-scale conspiracy involving local officials and businessmen. Their low-key investigations, driven more by curiosity and a sense of decency than by thrills, peel back layers of bureaucratic hypocrisy and petty corruption while introducing a cast of eccentric characters and comic mishaps. The story blends gentle mystery, social commentary and warm, dry humor, often underscored by a love of jazz and everyday human decency.
