December, 1940. Christmas is coming, but the season of goodwill is overshadowed by the death and destruction of the Blitz. In London's Covent Garden, where the glamour of theatreland rubs shoulders with the bustle of the capital's biggest fruit and vegetable market, the war has closed the theatres and ruined the market trade. When a daylight air raid hits the Prince Albert Theatre in Drury Lane, rescuers find a man dying in the wreckage. But it wasn't the bomb that's ending his life - he's been stabbed, and with his dying breath he whispers what sounds like a fragmented confession. As Detective Inspector John Jago begins to investigate, there's an underlying question he must grapple with: was the murdered man himself a killer?

As dawn breaks on a chilly morning in November 1940, a car is found ablaze in an abandoned builder's yard a stone's throw from the Regent's Canal in Camden Town, north London.

He liked to be known as Lucky Les, but it seems his luck has finally run out. DI John Jago discovers among Latham's belongings a mysterious photograph and some suspicious-looking petrol ration books that set Jago off on a murky trail of deceit, corruption and murder.
