The Teaberry Strangler by Laura Childs, 303 pages

It was the Dickensian evening Theodosia Browning had been hoping for. Charleston shop-owners dressed in cloaks of yore threw open their back doors to visitors, who took advantage of bargains and Theodosia's delicious teas.

But later, the alleys clear except for one body- which a horrified Theodosia discovers. It's Daria, the map store's owner. Locals have shown interest in buying her shop-but enough to kill? Plus there's been a customer hell-bent on acquiring a not-for­sale map. Most alarming of all theories, however, is Detective Tidwell's: the killer mistook Daria for Theodosia. And if that theory holds, the killer's work isn't done.
