This is a great book. A thriller that links the past and the present and has a real Britishness to it. It has a similar feel to Prime Suspect with characters that ring true. Nigel the genealogist is an unlikely but brilliant hero. The linking of the past to the present is effortlessly done taking you on a real journey through the past. Brilliantly written, it passed the couldn't put it down until it was finished test, the mark of a good thriller. Much better than the implausible "conspiracy" thrillers that are all the rage at the moment. Great plot, good characters, well written, read it!
