This sparkling second novel by the highly regarded author of The Thirteenth Life of Frank Finnigan revolves around three main characters who each narrate the novel's three sections. Adrian is a musician in a percussion group, he's a bit of an obsessive; music is his life, and he is becoming enamoured with Cara, who is married. An affair looms. Michael is Cara's husband. He's a psychotherapist and a thinker, a bit of a bore, it seems; he has a difficult client called Vincent, who is stalking him. There's a threat of danger in the air. Cara herself is flattered by Adrian's attentions and is drawn to the music, the dancing and the sheer vitality of the world he inhabits. It's while Cara is telling her story that the novel produces an unexpected twist. A simple story becomes complicated. Violence suddenly explodes, and a big surprise is revealed. Things have definitely not been at all that they seemed. As the reader we find ourselves reviewing what we've read; were there any clues? Palmer tells a technically adroit story with a thriller twist. Rhythm is an entertaining example of the literary thriller genre.
