After eleven straight months of discovering a dead body a month, librarian Mira James thinks she's finally broken her bad luck streak. That is until she finds a disturbing note in a book, a clue that could lead to breaking open one of Minnesota's biggest crime syndicates. She follows the trail and is horrified to discover that it leads to her father, who died 13 years earlier. To make matters worse, Mira catches wind that her sexy Adonis boyfriend, Johnny, is planning a surprise for her. Problem is, she doesn't know if it's a marriage proposal or an intervention. As Mrs. Berns and Mira take on their final case together, Mira discovers it's more personal than she could have imagined, and that she holds the fates of her dearest friends in her hands.
