This is by the author of The Legacy, see below, which won the Channel 4 TV Book Club, last year.
I also loved this book. It had it all, deception, murder, and is a classic time slip novel.
Interwoven with this is a subplot involving the suffragettes and particularly the different treatment/punishment meted out to women dependant on their class.
This would make a superb reading group novel, there is just so much to discuss. An innocent and naive vicar and his wife, theosophy, forgery and an interesting modern story involving the archaeology of the War graves Commission in France - something I had never thought about before. Just how do they identify remains that turn up in a field in Northern France.
All in all I thoroughly recommend this book, it will keep you enthralled and immersed in it up until the end.
