The 12.30 from Croydon

The 12.30 from Croydon is a detective novel by Freeman Wills Crofts first published in 1934. It is about a murder which is committed during a flight over the English Channel. The identity of the killer is revealed quite early in the book (making it an early example of the inverted detective story or "howcatchem"), and the reader can watch the preparations for the crime and how the murderer tries to cover up his tracks. The final chapters of the novel are set in a courtroom and during a private function at a hotel, where a résumé of the whole case is given in front of a small group of police detectives, solicitors, and barristers.
