The Hollow Man

From the hilltop he could see London, stretched towards the hills of Kent and Surrey. The sky was beginning to pale at the edges. The city itself looked numb as a rough sleeper; Camden and then the West End, the Square Mile. His watch was missing. He searched his pockets, found a bloodstained serviette and a promotional leaflet for a spiritual retreat, but no keys, phone or police badge.
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 Bishop's Avenue, one of the most expensive streets in the city. Belsey sees a chance for a new life.
But someone else got there first.
