A floating palace, an unruly appliance, and a killer on the loose . . .

When one of Irma's friends asks for help vetting a potential suitor, she's sure that a little digging into his past will do the trick. But after she discovers that a robotic appliance might be on a rampage in the almost-beau's swanky houseboat community, she sets out to entice Violet into unravelling another technological snafu.

It takes some doing to properly motivate Violet, and even worse, a strange young man has been skulking around Irma's house, alarming Mr. P, her furry sidekick. On top of that, there's a new sheriff in town who's been raising Irma's hackles—along with her curiosity about what's happened to Chief Pickle.

After a loved one is injured and a friend's son is arrested for murder, Irma has to confront her idea of family—and what she's willing to do to protect hers. Will she and her crime-fighting companions join forces to find a killer . . . or die trying?
