London's East End has always been a social and racial melting pot and never more so than today. PI Lee Arnold and his assistant Mumtaz Hakim don't mind - it keeps them on their toes. It is November. The days are getting darker and they have a new case on their hands. A young Asian couple moves into a dilapidated house in Upton Park. The woman, Nasreen, spends much of her time working alone on the house, her husband Abdullah preoccupied with his job. John Sawyer is a veteran of the war in Afghanistan. Since his discharge, he has been volatile and is now homeless. An unlikely friendship develops between Nasreen and John, one that her husband would frown upon. When John's body is discovered, Nasreen's suspicions light upon Abdullah. Did he know they were friends? Reluctant to go to the police, Nasreen reaches out to the Arnold Detective Agency. Mumtaz Hakim begins to dig into Abdullah's past and into the house itself which, she finds, holds its own grim secrets.
