This was fantastic and had the best ending.
Basically its written in two parts. The 1st being about a 13yr old girl who goes missing from a tiny village around the time of the moors murders 1963. It follows the copper who is in charge of the case, the seach and subsequent trial etc.
The 2nd book is set in 1994 and is about a journalist who is writing a book about the case when some new information emerges.
The ending is absolutely superb and I really really enjoyed this one.
