The Good, the Bad, and the Emus

Meg's paternal grandfather has hired Stanley Denton to find her grandmother Cordelia. 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 longtime neighbor. Stanley and Meg agree to help track down the killer. But then the neighbor is murdered, and not only Cordelia's cousin but also the entire contingent of emu-rescuers are suspects.
