When Retta's "gentleman friend" is accused of murder, the Sleuth Sisters take on the case. Winston Darrow is a charmer, but his secrets create trouble that spills onto sisters Retta, Barb, and Faye, and even police chief Rory Neuencamp. Someone is out to harm Win, someone he claims committed the crime he is suspected of committing. While Retta admits that Styx, her daffy Newfoundland dog, is more trustworthy than Win, she doesn't think Win is capable of murder. Mysterious men pop up wherever the sisters go, each more threatening than the last. What do they want with their client? As the situation turns more dangerous, they hide Win at Rory's cabin, reachable in a Michigan winter only by snowmobile. In the frozen wilderness, Barb and Retta must ignore their differences and work together to stay alive. Back at home, Faye faces a deadly enemy with only her rescue dog and a couple of horses for help. If they all live through this investigation, it will be due to sister solidarity, doggie instincts, and loyal friends. But really, who could ask for more?
