A Wall Road Journal bestseller

All Detective Mason Callahan wanted was a quiet fishing trip with the guys—an opportunity to escape and unwind before Halloween.

Until he finds your body of his boss, Denny Schefte, near their remote control Oregon cabin. Right now all he desires is to capture the sadist who slit Denny’s throat and protected his face with a mask. Mason was the last person to find out him alive and can stop at nothing to discover his friend’s murderer.

When the FBI learns of the mask still left at the picture, they realize they have a serial killer on their hands—person who is targeting cops. They assign the case to Unique Agent Ava McLane, despite her engagement to Mason. Barely retrieved from her personal nearly fatal injury and her sister’s attempted suicide, Ava expectations she is ready to chase another killer.

But mainly because she delves in to the increasingly disturbing case, the killer could be closer than expected—dangerously close.
