A World War II thriller by a multimillion-selling, Edgar Awardwinning author.

As plans for D-Day loom large, the agents of Department Z-a secret detective unit within British intelligence-are working overtime to halt the leaking of intelligence to Berlin. Meanwhile, three cousins undertake their own covert operation: meeting in a cottage in Guildford to discuss a dark family matter in secret.

As these two seemingly unrelated events collide, the cousins are drawn along a secretive trail that leads to a powerful spy ring. The team faces a race against the clock, as they fight to infiltrate this tight-knit organization-or risk devastating consequences ...

"Following closely on the heels of history, and sometimes a little ahead of it, Mr. Creasey and Department Z are busy preventing someone from putting a spoke in the wheels of the Allied invasion of Europe." -Evening Chronicle
