Murder on the Flying Scotsman

In the spring of 1923, the Honourable Daisy Dalrymple boards the Flying Scotsman to research an article, only to find herself amidst a family feud. An old schoolfellow, Anne Breton, and her relatives are rushing to the deathbed of their notorious miser uncle, Alistair McGowan, each hoping to sway his will. When Albert McGowan is found murdered on the train, Daisy, already occupied with a runaway child, is surrounded by a train full of suspects.
