A skeleton with broken fingers—a boy alone in the cold Maine woods—a father too terrified to come out of hiding.

Why does a carpenter get fatally assaulted at architect Iris Reid's new museum project? And why was a man's tortured body hidden under the floorboards in the very same spot twenty years before?

Now the media is calling the site "the museum of horrors" and Iris must uncover the link between the two crimes before the killer curates his next victim. Can she stay ahead of this adversary who will stop at nothing to keep his shocking secret hidden?
