About this book

The Sixth Wicked Child concludes the 4MK trilogy. Detective Sam Porter confronts buried memories when the words "Father, forgive me" resurface from his past. For Anson Bishop, these same words connect his childhood to present events as he reveals a truth hidden for decades. Multiple victims are discovered in Chicago and South Carolina with "See No Evil" written on cardboard near each body. The victims are found within minutes of each other and appear connected despite the geographical distance between them. Chicago Metro and the FBI face mounting chaos: a hospital lockdown, a rogue officer, and corruption within their ranks. When Anson Bishop, the prime suspect in the 4MK serial murders, turns himself in, he provides an unexpected account that fundamentally alters the investigation and affects everyone involved. The novel unravels the past at rapid pace, revealing the Four Monkey Killer's motive in this final installment of the series.
