From Super Detective Picture Library #181, September 5, 1960.
In the early days of WWII as the Germans rapidly approached France, The British Expeditionary Force was racing to Dunkirk to flee back to England. A few brave men stayed behind to mount a delay and most died doing so. A couple were captured and held as POWs. One was actually a Czech who was the son of the main Resistance leader in that country and unfortunately knew the names of all the key players. It is John Steel's job to free the man before the Germans learn his real identity and knowledge.
