Meg's paternal grandfather has hired Stanley Denton to find her grandmother Cordelia. Stanley has found a trail to his long-lost love in a small town a short drive away. He convinces Meg to come with him to meet her, but unfortunately, the woman they meet is Cordelia's cousin - Cordelia died several years ago, and the cousin suspects she was murdered by her long-time neighbor. Stanley and Meg agree to help track down the killer. Grandfather even has perfect cover: he - along with most of Meg's family and friends in Caerphilly - will stage a rescue of the feral emus and ostriches that infest this town. But then the neighbor is murdered, and not only Cordelia's cousin but also the entire contingent of emu-rescuers are suspects.
