The Best of Our Spies by Alex Gerlis
In the Pas de Calais, Nathalie Mercier, a young British Special Operations Executive secret agent working with the French Resistance, disappears.
In London, her husband Owen Quinn, an officer with Royal Navy Intelligence, discovers the truth about her role in the Allies' sophisticated deception at the heart of D-Day.
Appalled but determined, Quinn sets off on a perilous hunt through France in search of his wife. Aided by the Resistance in his search, he makes good progress. But, caught up by the bitterness of the war and its insatiable appetite for revenge, he risks total destruction.
Based on real events of the Second World War, this is a thrilling tale of international intrigue, love, deception and espionage, perfect for fans of Robert Harris, John le Carre and Len Deighton.
