A diplomat shoots his mistress, then himself, in a Nice hotel room, leaving behind only a confessional letter and a vow of vengeance from his closest friend. So begins William Le Queux's intoxicating 1927 mystery, where secrets fester beneath the polished surface of British high society like wounds that will not heal. Leonard Lydon, a modest radio engineer, inherits his friend Hugh's final wish: to expose the blackmailers who drove him to this desperate act. But Leonard soon discovers that truth is a dangerous currency in a world where every handshake conceals a blade and every smile masks calculation. When Leonard falls for Gloria Stormont, a charming heiress from a wealthy but faltering family, he inches closer to the rot at the heart of things. Her uncle Howard Stormont moves through London's finest circles with ease, yet his business dealings grow increasingly suspect. As Leonard pieces together the blackmail network that destroyed Hugh, he must confront an agonizing question: how can he honor his friend's memory when doing so means destroying the woman he loves? Le Queux weaves class tension, romantic intrigue, and moral ambiguity into a tapestry that feels remarkably modern despite its Edwardian trappings. For readers who crave Golden Age mysteries where the stakes are not merely whodunit, but what price will be paid for knowing.
