Amber Knight is London's hottest ticket - pop star, film star, the front-page subject of daily tabloid gossip. Nick Belsey is less celebrated. His decade-long career at Hampstead CID seems to be coming to an end, and his habit of getting into serious trouble is ongoing. He is currently of no fixed abode. But when Belsey is asked by a desperate mother to help find her son, he finds himself infiltrating the entourage of Amber Knight. It is a world of excess, obsession, lust and greed - precisely as Belsey had expected, and perhaps even hoped for. Soon, though, the blood begins to flow, one sickening crime is followed by the next, and Belsey finds himself in a far more deadly world, whose mysteries he must solve and whose grip he must escape.
