A missing woman. A surprising suspect. A curious conundrum.

The senior sleuths have a knack for sniffing out trouble, but when a missing woman cold case falls in their laps, all hands must be on deck to solve it. Unfortunately, this case hits a little too close to home, and quickly becomes an active case with dire consequences if they're not careful.

To complicate matters, Eunice is planning an authentic barn dance for the residents of Greener Pastures Convalescent Center. She needs the senior sleuths' help, and that means they must forgo their investigation.

The group will have to employ their best tactics to stay under the radar to root out the true culprit and avoid a barn dance disaster.
