Murder on the Flying Scotsman (Daisy Dalrymple Mysteries, Bk. 4)

In the spring of 1923, the Honourable Daisy Dalrymple takes a famous train, the Flying Scotsman, to go to Scotland and research a new article. Once on board, she bumps into an old schoolmate, Anne Breton, who, along with all her relatives, is en route to the deathbed of the family scion and notorious miser, Alistair McGowan. Alistair's will leaves the entire family fortune to his brother Albert, to the great dismay of many others in the extended family.

When presumptive heir Albert McGowan is found dead - murdered - on the train, Daisy is now surrounded by an entire family of suspects, and becomes embroiled in a complex murder investigation.
