Lying Beside You by Michael Robotham

Cyrus Haven and Evie Cormac return in Robotham's latest page-turning, psychological thriller in this "gripping and eerie" (Karin Slaughter) series, reaffirming why Stephen King has proclaimed this author "an absolute master."

If I could tell you one thing about my brother, it would be this. Two days after his nineteenth birthday, he killed our parents and twin sisters because he heard voices in his head. As defining events go, nothing else comes close for Elias, or for me.

As a boy, Cyrus Haven survived a family massacre and slowly pieced his life back together. Now, after almost twenty years, his brother is applying to be released from a secure psychiatric hospital—and Cyrus is expected to forgive Elias and welcome him home.

Elias is returning to a very different world. Cyrus is now a successful psychologist, working with the police, sharing his house with Evie Cormac, a damaged and gifted teenager who can tell when someone is lying. Evie has gone back to school and is working part-time at an inner-city bar, but she continues to struggle with authority and following rules.

When a man is murdered and his daughter disappears, Cyrus is called in to profile the killer and help piece together Maya Kirk's last hours. Police believe she was drugged and driven away from the same bar where Evie is working. Soon, a second victim is taken, and Evie is the only person who glimpsed the man behind the wheel.

But there's a problem. Only two people believe her. One is Cyrus.

The other is the killer.
