Recently unemployed, Faye Burner talks her retired sister Barbara into opening a detective agency. Their first few months are disappointing, since no one in their small Michigan town believes two fifty-something women can (or should) be private investigators. Faye wants to ask their well-connected sister Retta for help, but Barb insists she's too bossy to be included in the business. Without telling Barb, Faye lets Retta in on some details when they get their first real case: locating a man accused of murdering his wife and brother-in-law. Retta is helpful, as Faye knew she would be, but since she and Barb are both interested in the town's handsome new police chief, things become uncomfortable when they're all in the same room. When the sisters find the man they're looking for, bad things begin to happen, escalating from scare tactics to assault to murder. Someone doesn't want the old case stirred up, and that person is willing to kill. If the three Sleuth Sisters don't learn to work together, they'll be less one sibling!
