In his most thrilling mystery yet, private investigator Henry Walsh dodges bullets, bombs, and married women to help find a friend's missing fiancé...

Just as he's about to begin the search, an explosion rocks the marina where his friend was staying. When divers from the Sheriff's Office come up out of the water empty handed, Henry can only fear the worst.

But he keeps his promise, and leaves no stone unturned as he continues his search for his friend's fiancé. And as he hunts for those responsible, it's Henry who soon becomes the hunted.

The target on his back only grows, and he must fight to keep those around him out of harm's way.

His normally hard-shelled partner Alex is worried they're in way over their heads. She pleads with him to leave it in the hands of the Sheriff's Office.

But walking away was never Henry's thing. And he knows once he has all the pieces, he'll have no problem making them fit.

As long as he can stay alive...

When Henry finally discovers the one thing everyone's been after, getting it into his hands is his only option.

Apparently, it's a treasure worth killing for...
