The Sixth Wicked Child : A 4MK Thriller Book 3

In the riveting conclusion of the 4MK trilogy, Barker takes the thriller to an entirely new level. Don't miss a single word of the series James Patterson called "ingenious."

Hear No Evil

For Detective Sam Porter, the words “Father, forgive me” conjure memories long forgotten; a past intentionally buried. For Anson Bishop, these three words connect a childhood to the present as he unleashes a truth concealed for decades.

See No Evil

Found written on cardboard near each body, these words link multiple victims to a single killer—discovered within minutes of each other in both Chicago and South Carolina—clearly connected yet separated by impossible miles.

Speak No Evil

Chicago Metro and the FBI find themselves caught in chaos—a hospital on lockdown, a rogue officer, and corruption at the highest levels. When Anson Bishop, the prime suspect in the notorious 4MK serial murders turns himself in, he reveals a story completely unexpected, one that not only upends the current investigation, but one that will change the lives of all involved.

Do No Evil

With unrelenting tension and pulse-pounding suspense, the past unravels at breakneck speed as the truth behind the Four Monkey Killer’s motive is finally revealed in this masterfully crafted finale.
