Annie Abbott is a busy woman. As well as attempting to create her grandchildren's best ever Christmas and helping her police detective daughter Tina juggle work, kids and Christmas preparations, she's been roped in to run a pottery shop after a shopkeeper friend was injured in a robbery.

But this is Annie Abbott, which means a mystery isn't far away.

Why did the thief steal the ugliest trinket in the shop? Why does the same trinket, a kitsch pottery reindeer, keep turning up in unexpected places? And is it all related to the state of the drains running along the back of the shop, at Lyme Regis's Old Mill?

Christmas doesn't stop Annie and the swimming club gang from interfering in another case in this gripping festive mystery set on the Jurassic Coast.
