Gabriel Book is an erudite and unconventional London bookseller married to Trottie, the owner of the wallpaper shop next door. He is also a sleuth who uses the chaotic riches of his stock to crack the puzzling cases that come his way. He does not work alone.

Book's shop is a magnet for waifs and strays - some of whom bring mysteries of their own to his door. There's Nora, sometime bookseller and true crime enthusiast; Dog, the purveyor of ginger biscuits and then Jack, whose arrival to the shop forces Book to confront a loose end from his own past. Clever, endearing and entertaining, Bookish is a warm-hearted and unexpected mystery, about books, murder and the secrets we all keep.
