The Sixth Wicked Child: A 4MK Thriller Book 3, Hardcover

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.
