When two impossibly rich oil tycoons are found murdered in their own homes, a matter of life and death becomes one of national security. Jim Burke of Department Z is called in to stop this ambitious murderer from killing again-but it isn't long before Burke's investigation is derailed by an attempt on his own life.

Will he be able to save Britain from this latest threat and escape unharmed? Burke knows that he's up against something big-but is it too big for this new secret service man to handle?

This exciting thriller is part of the classic series starring the agents of Department Z, from the multimillion-selling, Edgar Awardwinning author.
