Retired Navy Pilot Angel Warren's sleuthing days are behind her. At least, that's what she tells herself after finding two dead bodies during her first year back in Stonebridge, Pennsylvania. Murders make customers wary and Angel's sales are suffering. With her daughters back in college and the cases behind her, Angel focuses on attracting more customers into her novelty shop.

Hoping to boost local tourism, Angel researches how to create a walking history tour. During a dry run for her inaugural walk, her brother's Pomeranian leads her through the woods and to her third body, the apparent victim of multiple stings from a nearby wasp nest. Angel recognizes the deceased as her sister's cherished employee who was days away from being married.

The scene doesn't sit right with Angel's best friend, Detective Trinity Colson, however, who suspects foul play. When the autopsy reveals a different cause of death, Angel dives into her most dangerous case yet. Soon Angel, along with her eclectic crew featuring two dogs and a feisty parrot, are once again on the hunt for a murderer. But is Angel also being hunted?
