Enoch Bale stalked the streets of New York City nearly one hundred and fifty years ago.

He is long dead.

He is long forgotten.

But he is not long gone...

Archaeologist Carrie Norton makes a startling find in a historic New York City site: the remains of a Civil War-era murder victim. Detective Max Slattery sees something more-uncanny parallels to a recent series of brutal slayings. What seems impossible becomes terrifyingly real as Carrie and Max's investigation unearths a conspiracy between the living and the dead nearly two centuries in the making-one that has yet to claim its final victims.
