A foolproof method for earning a fortune in a short space of time is discovered by some enterprising young men. But they haven't bargained on finding themselves involved in blackmail and then murder. It falls to Inspector French to unravel the threads with his usual flair. Rip-roaring mystery and suspense from the author of Mystery on Southampton Water and Antidote to Venom. Freeman Wills Crofts was born in Dublin and worked in railway engineering before turning to detective fiction. To his plots he brought a mind trained in mathematics, specialising in the seemingly unbreakable alibi and transport timetables. His best-known character is Inspector Joseph French, who appears for the first time in Inspector French's Greatest Case. French achieves his results through dogged persistence. Raymond Chandler praised Crofts' plots, calling him 'the soundest builder of them all'.
