It's finally spring in English Village, and local reporter Josie Posey reluctantly agrees to write about the snooty Cleeve Hill Garden Society's annual Garden Tour. When the tight-lipped socialites give her a chilly reception, Josie is determined to unlock the secrets behind their garden walls.

But before she can dig into the story, Josie takes on a cat-sitting job for her favorite bank teller, Maryann Penny, who has enlisted her help. Arriving at Maryann's to check on the cat, Josie is shocked to discover the young woman dead: lying peacefully on a suspicious bed of cash in the antique bathtub of her home.

Suddenly, Josie is a prime suspect in a puzzling murder with no weapon, no motive, and no cause of death. To clear her name, she and her Mahjong Maven buddies are on the trail of a killer again. With her Old English Sheepdog Moe and a fluffy cat named Johnny Depp in tow, Josie checks out a red-haired real estate agent, a handsome dentist, and a Peruvian professor in her search for suspects.

The police chief warns Josie to stay out of his case. The editor of The Village Gazette demands exclusive reports on the Garden Tour and Maryann's murder. And the meddling mavens are digging up dirt to figure out who's making a killing from counterfeit cash.
