Operation Stalag (Large print, Paperback, Large Print edition)

Late in 1942 Dutch Underground agents delivered to British Intelligence an insane young RAF pilot - the sole survivor of fifty others, all shot in cold blood. Churchill suspected a massive blackmail threat involving 100,000 Allied POWs in German camps. So B. I. ordered its crack commando squad into action. Under the leadership of Lieutenant Crooke, V.C., they set off on a dangerous mission into Nazi Germany to find the unknown Gestapo killer.
