Fast-paced and filled with pulse-pounding, heart-wrenching suspense, the final instalment of the beloved Knox and Sheppard Mysteries brings the journey of P.I. Madigan Knox and Detective Grace Sheppard to a dramatic and emotional conclusion.

Two sisters with a troubled past.
A murderer with a kill list. How long until he gets to them?

Grace was seven years old when her sister told her she saw a dead body in their childhood foster home. Between that and the drug trafficking her foster father was eventually arrested for, it's no surprise that Grace wound up a detective.

But Grace's world is turned upside down when she discovers her current homicide investigation is connected to similar murders in the neighbouring city of Amherst. Is she chasing a serial killer? Going back to the city where she began her career is complicated to say the least—her old colleagues seem hellbent on jamming her up.

Grace's sister Madigan isn't a detective in the official sense, but that doesn't stop her from answering a call for help from John Talbot, another child who spent time in the same foster home. John believes someone is after him…and it might be related to a crime their foster father committed—one that was never pinned on him. It's not the first time John has dragged Madigan into a dangerous situation, but her loyalty knows no bounds.

And after a shocking discovery, the sisters shift their goal to staying alive. It seems that anyone with a connection to their past is in danger. Someone is tying up loose ends…and fast.

In this race against time, it will take more than the bonds they've forged to survive.

    Holy moly! This finale is just action-packed, full of secrets, and fraught with peril! I read it in one sitting because I couldn’t bear to put it down. This ties up all the loose ends and even exposes ones that were not obvious. I really enjoyed how things wrapped up for Grace and Madigan. They truly deserve to be happy. I have loved reading this series and am sorry to have it end. I do look forward to reading whatever Emerald O’Brien writes next. She is a wildly talented author.
