The Clockmaker's Daughter by Kate Morton

In true Kate Morton fashion, this is a mystery that spans generations but the key difference is that there are so many narrators you might need to keep a pen and paper handy. An artist's retreat to an English manor house in 1862 which began as a lark ended in tragedy with a woman dead, a love affair gone awry, a priceless pendant missing and an artist who was never quite the same again.
Fast forward through all the various owners of the manor and family members and we come to Elodie who is trying to understand her mother and also solve a puzzle which involves the contents of the artist's valise both of which will bring her to the doorstep of Birchwood Manor. We also have a quiet but persistent ghost who must now spend her time trying to guide the inhabitants of the manor. I always enjoy Kate Morton's unique combination of an interesting property, characters that draw you in and a lasting mystery that begs to be solved.
