May the best man die! July, 1923, and Daisy has been invited by an American magazine to cover the Henley Regatta. But unknown to her, she steps right into a class war between two members of the Oxford rowing team. Cox Horace Bott - a shopkeeper's son and scholar student - has always hated rower Basil DeLancy - younger son of an earl and all-round cad and bully. And after a particularly brutal public humiliation by DeLancy, Bott swears revenge - so when DeLancy keels over and dies mid-race, it would seem he's made good on his promise. Yet Daisy isn't convinced, and with the help of her fiance Detective Inspector Alec Fletcher of Scotland Yard, she dives into a tangled web of jealousies and secrets, where appearances are everything and good breeding may just be a cover for a killer intent on keeping Daisy mum forever.
