The Fourth Monkey by J. D. Barker digital book - Fable

Publisher Description

The first in the 4MK Thriller series comes a dark and twisting novel from the author Jeffrey Deaver called "a talented writer with a delightfully delicious mind."

Two days to save her . . .

For over five years, the Four Monkey Killer has terrorized the residents of Chicago. When his body is found, the police quickly realize he was on his way to deliver one final message, one which proves he has taken another victim who may still be alive.

One day . . .

As the lead investigator on the 4MK task force, Detective Sam Porter knows that even in death, the killer is far from finished. When he discovers a personal diary in the jacket pocket of the body, Porter finds himself caught up in the mind of a psychopath, unraveling a twisted history in hopes of finding one last girl, all while struggling with personal demons of his own.

Zero.

With only a handful of clues, the elusive killer’s identity remains a mystery. Time is running out as the Four Monkey Killer taunts from beyond the grave in this masterfully written fast-paced thriller.

“No me gustó mucho, me pareció aburrido la trama, no me atrapó, no sabía que era una trilogía, el tipo anda suelto… hay que seguir leyendo a ver qué pasa. No se si lo haré. De quién era los ojos azules de el final? Ahí quizás me perdí.”
