When Heather Shepherd gets a call from her husband, Detective Ryan Shepherd, she's sure she's about to be called up to consult on yet another case.
Heather's right of course, but the victim is someone she's never heard of before. A new, and seemingly innocent, librarian who didn't have any enemies. Or did she? Heather's determined to get to the bottom of this one, and sets off on another sleuthin' adventure armed with a box of her Pecan Nut Crunch Donuts, the help and hindrance of her bestie, Ames, and the drive to do the right thing for the residents of Hillside. But the victim's past is shady, and the suspects are thin on the ground and all seem to have alibis, apart from one - a mysterious stranger who hangs out in the library too often.
Heather's on the case, lack of evidence aside, and she has to solve the case or risk the killer escaping Hillside and moving on to terrorize parts unknown.
