Murder stalks the halls of Ballantyne Manor... September 1926: When flapper Clara Camden arrives uninvited to Charles Ballantyne's 60th birthday celebration, she becomes entangled in a web of deadly secrets. As a violent storm cuts off all escape from the gothic mansion, a series of murders rock the estate's very foundation—and Clara discovers she may be the killer's final target. Detective Alexander Rios must race against time to unmask the murderer among them. But nothing at Ballantyne Manor is quite what it seems. Each guest harbors their own dark secrets, from bootleggers and blackmailers to exiled nobles and Jazz Age starlets. As bodies pile up and family scandals emerge, Clara uncovers a shocking truth: her connection to the Ballantyne family runs deeper than anyone suspected. In this atmospheric tale of murder and inheritance, speakeasies and sapphires, love and betrayal, author G. Robert Cartier weaves an intricate mystery worthy of Christie herself. With period-perfect details and unforgettable characters, "Poison in the Blood" transports readers to the glittering yet dangerous world of the American Jazz Age, where old money meets new crime and even the most trusted servant may prove deadly.
