Who killed this wealthy couple? It doesn't take a clue-sniffing Golden Retriever's sense of smell to know something is up. For semi-reformed computer hacker Steve Levitan, his long-time girlfriend, Lili, is acting out of character, and he's eager to figure out why and how he can help her. But that gets delayed when Steve and his golden Rochester are brought onto investigate a double homicide in a posh neighborhood of Stewart's Crossing. Boris and Natalya Krimsky were both murdered in their mansion, and Steve's early forays into their personal data reveals a plethora of suspects. There are people cheated out of millions and people betrayed out of their American dream, each with a motive to kill the couple. But as Steve and Rochester delve deeper, they find that the motive to kill the couple might have a far more disturbing origin, and catching the killer requires Steve to bend all of the rules as a semi-reformed hacker. With wit, heart, and canine antics, the team goes nose to the ground to bring a killer to justice, and to give Steve a new perspective on what makes a family.
