I really enjoyed reading this book. It didn't feel like I was reading a book but that I had sat down with Leo Marks and he was telling me stories about his coding work during WWII. This was a fascinating look into the work that SOE did during the war. You can tell that Marks grew close to those he worked with and you could feel his grief when some of his most beloved co-workers were killed. It was heartbreaking reading about those deaths. I loved Leo's sense of humor; even with the seriousness of the war he still managed to make me laugh at odd times throughout the book. I would recommend this book to those wanting to know more about code making during WWII.
