This is the story of Derek Niemann and his family. The author was born and raised in Scotland, and he happened to discover that his grandfather was an SS officer during World War II. He went on a search to find out more about his German heritage and what his grandfather was involved in during the war. This was a very good book. I wonder how many other people are like this author, with their family hiding secrets under the rug or not knowing anything about the past of someone so central in their lives. I would suggest this book to anyone interested in World War II.
