Zack Tripler, a psychiatrist treating a psychotic patient, descends into madness and finds himself at the nexus of a deadly plot.

The only clue is a coded message on the patient’s computer. When his patient Youssef is found dead, either by suicide or murder, Zack becomes entangled with Youssef’s widow Jamilah in her effort to solve the mystery of her husband’s death. But nothing in Zack’s world is as it appears as he swings between concern for Jamilah’s safety and suspicion that she is responsible for Youssef’s death and is part of the terrorist plot that he suspects.

Can he trust anyone in his struggle to survive and to hang onto the last remnants of his sanity? Can you guess who murdered his patient and what drove Zack mad? Share his hallucinations and terror through his eyes and try to unravel the mystery.

If you enjoyed the twists in The Silent Patient by Alex Michaelides or the big reveal at the conclusion of The Sixth Sense, you’ll delight in the diabolical twists that will tease and challenge you in Shared Madness.
