Detective Nick Belsey needs help. Something happened last night – something with the boss's wife – and Belsey needs to get out of London, and away from the debt and the drink and the deceit. Collecting his belongings back at Hampstead CID on what should be the last day of his career, Belsey sees a missing person's report. But this one's different; this is on the Bishops Avenue, one of the most expensive streets in the city. Belsey sees a chance for a new life.
