A Killer's Mark

The only way to stop him is to chase him — and chasing him is exactly what he wants.

FBI Special Agent Aidan O'Reilly is haunted by the one that got away — a madman responsible for over fifty brutal murders. It's the case that consumes him. The one he can't close. The one that took a close family friend and left the agent with a promise he's desperate to keep.

Every anniversary, another woman is found posed in a black dress, white carnations in her hands, and a note with Aidan's name on the body. Ritualistic. Deliberate. An infamous butcher who wants the world to know he's untouchable.

But now the killer has found an audience. After slipping a birthday card to an ambitious, reckless reporter chasing the headline, the sociopathic fiend isn't just taunting the embattled agent anymore. He's performing. And a man who wants the world watching isn't interested in staying hidden — he's interested in a finale.

With a psychopath operating just out of reach and a reporter hellbent on glory, Aidan scrambles to stay ahead of a clock counting down to a very intimate death.
