When you're fighting organised crime, you need a detective who is willing to use unconventional methods. So when a slew of counterfeit clothing coupons threatens the stability of the wartime economy, the British government turns to Len Wyatt, an unscrupulous private sleuth, who is tasked with infiltrating London's criminal underworld. But as Wyatt comes to grips with the racket he has been assigned to uncover, he soon realises that this is no ordinary ring of privateers, but a plot so underhand and sinister as to shock even his cynical philosophy.
Originally published in 1944, this gritty crime thriller is memorably set against the background of Blitz-torn London.
