The False Inspector Dew
Peter Lovesey
 It is 1921, and Alma Webster, a reader of romances, is passionately in love with her dentist, Walter Baranov. There is only one foreseeable outcome: the murder of his wife. Inspired by the real-life Dr Crippen case, they plot a way to achieve it perfectly aboard the ocean liner, Mauretania. The dentist takes on the identity of Inspector Walter Dew, Crippen’s nemesis, but then a murder occurs aboard the ship and the captain invites "Inspector Dew" to investigate.
