The murder of a personal fitness trainer draws DCI Bill Slider and his team into a baffling investigation where nothing is as it first appears. Fitness trainer Erik Lingoss is found dead in his west London flat, his head smashed by one of his own dumbbells. His heartlessly-dumped girlfriend, blood on her clothes and hands, is the prime suspect. She had means, opportunity, and motive. But is the case as clear-cut as it seems? Handsome Erik Lingoss had clients in high places; and he seemed to engender powerful emotions. If it was a crime of passion, there was plenty of that to go round: love strong as death, jealousy cruel as the grave. Who did he let in to his flat that evening? Where is his missing mobile phone? Why is seven hundred pounds in cash stuffed under his pillow? The deeper Slider and his team dig, the clearer it becomes there's far more to this case than meets the eye.
