When Dodge, a German shepherd police dog, finds himself retired after an accident leaves him deaf in one ear, he's lucky to be adopted by the perfect family. Twelve-year-old Cassie Sullivan, his girl, smells almost as good as a dog, and gets her nose for sleuthing from her police chief mom and coroner dad. Cassie is smart and quick on her feet, and doesn't mind breaking a couple rules to get to the bottom of a mystery. Dodge has forty-two dog years of experience solving crime, as well as a great network of other four-legged colleagues when he needs more intel.
When Verdel Ward, the richest man in town, goes missing, it seems like everyone from the mayor to the housekeeper wants his fortune, which he's left behind with no will. But Cassie and Dodge can smell a mystery from a mile away, and can't help wondering why a miser would go swimming in a dangerous cove, what's up with the suspicious fiancee, who's been sneaking around the mansion, and where a twin brother has come from.
