Michael Robotham has written a complex and enthralling mystery novel. He has given the amnesia story line a new and captivating twist which kept me turning the pages. Though the story is complex the author thinks enough of the reader to provide all the information needed to solve the mystery before he reveals it. The story is highly suspenseful, but the author keeps the reader interested enough in the process of reaching the solution that you are not tempted to skip to the end.For a British author Robotham has a light touch and a fast pace. He is very adept at giving us the feel of London without heavy handed descriptions. He also has a simple and sure touch when filling out the characters in his tale.If cop dramas are your thing, you should read this book.
