P.R. Reid (1910–1990) was a British Army officer who was held captive at Colditz Castle when it was designated Oflag IV-C during the World War II era. Reid was one of the few to escape from Colditz, crossing the border into neutral Switzerland in late 1942 after two years as a prisoner of war. After the war ended, Reid became a diplomat and administrator before eventually returning to his prewar career in civil engineering. He is the author of several books on his time at Colditz Castle, which together were the basis for movies, television series, and a board game.
"[T]his book is highly recommended reading."
