Detective Sam Porter has taken time off from work as Lead Investigator on the 4MK case to heal emotionally after suffering a personal tragedy, but is called back to duty when a notebook believed to have been written by the Fourth Monkey Killer is found on the body of a man who was hit by a bus and killed. Has the 4MK Killer’s reign of terror finally come to an end? Also found at the scene is a white box tied up with black string containing the ear of an as yet unknown victim, meant to be delivered to the address of a prominent local businessman.
As the box is the first in a series of boxes usually delivered to the families of previous victims, it stands to reason that there is a girl somewhere who is still alive, and the race is on to find her before she succumbs to her wounds.
Porter and his team must use the notebook to solve the case that has baffled them for over five years and prevent further loss of life.
Masterfully written, this page-turner will keep you guessing right up to the end.
I read an uncorrected proof ARC of this book, and the opinions expressed in this review are my own and are unbiased.
