An act of kindness

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. A woman, Nasreen, spends much of her time working alone on the house, her husband Abdullah preoccupied with his job. John Sawyer is a homeless war veteran. 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. 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.
