Gladdy Gold may have gone from dyed-in-the-wool New Yorker to South Florida retiree, but she’s loving every minute of it. Between poolside gossip, a hot-to-trot boyfriend, and a booming detective business, life couldn’t be sunnier — until a trip back north with her sister Evvie leads to murder and mayhem starring the usual suspects.

Unbeknownst to Gladdy, her fellow detectives are hot on her trail. Sophie, Bella, and Ida no sooner land their tootsies in the Big Apple than trouble promptly finds them. But while the girls go deep undercover, posing as bag ladies to catch a criminal, there’s another surprise awaiting Gladdy. Her boyfriend, Jack, is in town too — and he’s reopening a 47-year-old cold case: the murder of Gladdy’s husband. Can Gladdy and Jack join forces to solve a decades-old crime — and maybe heal some wounded hearts in the process?
