Luckily, Gabriella finds unexpected help in Crooked Pass Security's unique investigative team. Expert tracker Diego Rodriguez and his faithful K-9, Poppy, go searching for clues from the ground up. But when the killer focuses on Gabriella, Diego---and Poppy---must keep her safe from the killer's dangerous grasp.
