A thrilling tale of wartime espionage by the acclaimed Alistair MacLean.

During World War II, Yugoslavian rebel forces struggle to resist the German occupation, even as a three-way civil war tears the nation apart. In the mist of this terrible confusion, three compatriots set out across their besieged country to relay the German battle plan and unmask a double agent. But where do their loyalties really lie? On this dangerous journey with dangerous companions, everyone's motives are uncertain—and no one is who he seems.
