This was the first book I'd read by Frances Fyfield, so I'm grateful to a reviewer who pointed me in the right direction. An intriguing, slightly creepy little tale of a girl who went wild and burned her boats, ran off to London and got in worse trouble. And comes home to the village of Pennyvale, a village by the sea, described as a perfect place, but which seems to me to have shadows over it. You can never see all of it from anywhere. It has secrets - including the life of Jessica's father who dies when she was 14.
Jessica's friend, Sarah - clearly a woman with a Past - comes to Pennyvale at Jessica's prompting, rents a cottage and promptly becomes tangled up in Jessica's story, Jessica's mystery. And she ends up trying to avenge her friend's death. This book has one of the oddest conclusions of any detective story I've read for a long time, and I'll now have to go back and read the earlier ones (it's great to find a series you can hoover up!) before - hopefully - any sequels are published.
