I am currently re-reading Sarah Helms' "Vera Atkins, A Life in Secrets" which covers the sending of SOE agents (principally female) to France and Atkins' efforts to discover the fate of those that did not return. Regarding the Low Countries, I have Herman Giskes "London Calling North Pole" and one of his adversary's tales "Inside North Pole" by Peter Dourlein which are both rivetting reads. Other books in a similar vein I have are "Odette" by Jerrard Tickel, "Of Their Own Courage" by Peter Churchill, "Saturday at MI9" by Airey Neave, "The Man Who Saved London" by George Martelli and "The Way Back" by Vincent Brome. Are there any biographies of Marcel Rousset (SOE codename Leopold) and Bernard Guillot (Free France agent), both of whom survived the war and gave lengthy debriefs? How about MRD Foot's "SOE in France" and "SOE in the Low Countries"?
