1st ed., 1979. 365 pp., frontis., + 4 diagrams + 5 maps. D.j., 22 x 14cm. FINE. Many famous escapes from Nazi-occupied Europe were made possible by a hitherto secret British service, MI 9. This small, dedicated and endlessly inventive team constantly exchanged coded letters with prisoners-of-war camps. It sent in money, maps, clothes, compasses, hacksaws; the prisoners sent out invaluable news of what was going on in the enemy's homeland. This book tells the full inside story of MI 9 for the first time.
