The teaberry strangler

After a particularly successful evening of sales, Charleston's Theodosia Browning discovers the body of map store owner Daria. Locals have shown interest in buying her shop--but enough to kill? Plus there's been a customer hell-bent on acquiring a not-for-sale 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.
