The sequel to The Guns of Navarone. Keith Mallory, Andrea and Dusty Miller are parachuting into war-torn Yugoslavia on a mission to ostensibly rescue a division of trapped partisans. In fact, it is to convince the Germans that a major Allied assault on Yugoslavia is imminent and thus draw troops from the Italian front.  Helped – and sometimes hindered – by a trio of Commando sergeants and a blind folk singer and his sister, the three need all the courage, darling and special techniques to accomplish their dual objective.
