A Treachery of Spies is an espionage thriller to rival the very best, a high stakes game of cat-and-mouse, played in the shadows, which will keep you guessing every step of the way.

An elderly woman of striking beauty is found murdered in Orleans, France. Her identity has been cleverly erased but the method of her death is very specific: she has been killed in the manner of traitors to the Resistance in World War Two.

Tracking down her murderer leads police inspector Ines Picaut back to 1940s France where the men and women of the Resistance were engaged in a desperate fight for survival against the Nazi invaders.

To find answers in the present Picaut must discover what really happened in the past, untangling a web of treachery and intrigue that stretches back to the murder victim's youth: a time when unholy alliances were forged between occupiers and occupied, deals were done and promises broken. The past has been buried for decades, but, as Picaut discovers, there are those in the present whose futures depend on it staying that way - and who will kill to keep their secrets safe...
