Hard Justice

When a biotech executive is found murdered in a Boston parking garage, Homicide Detective Sean Malone expects a routine investigation.

He is wrong.

The evidence points to OPUS—a secret neuroscience program that was officially shut down years ago after experiments into human memory and cognition went too far.

But OPUS never died.

Teaming up with Detective Sarah O'Connor, Internal Affairs' most relentless investigator and the one person Malone doesn't trust, he follows a trail of murders that leads from corporate boardrooms to City Hall and deep inside his own police department.

Someone has revived OPUS.

And whatever they created is no longer an experiment.

It is a weapon.

As more bodies surface, Malone discovers a survivor at the center of the killings—a man whose fractured memories may hold the key to every murder. But with powerful people determined to bury the truth, Malone realizes he is no longer solving a case.

He is trying to survive it.

Because the closer he gets to uncovering OPUS, the closer the killer gets to completing a list written years ago… inside a mind that never forgot.

Perfect for fans of Dennis Lehane, Michael Connelly, and Tana French.
