I really enjoyed this book, and am grateful to Reader's first for sending me an advance copy.
This is the second Tom Wilde book I have read, although I think you could read it as a stand alone without any problems.
In this book, Tom is sent to Scotland to investigate the helicopter crash which killed the King's brother. While there, he discovers that a woman has escaped from the crash, and when he tracks her down he becomes embroiled in a new mystery, which involves discovering Hitler's use of concentration camps.
Although it deals with very serious historical events, it is not a sad book, and there are plenty of light-hearted moments. I think the historical research into this book is very good and adds plenty of detail to the story. The main characters are nicely rounded, and those which have appeared in previous books are well developed in this book.
