Detective Jack Harney agrees to do an old Army buddy a favor. Curt Noble had some personal business to attend to, he didn't say what. What he did say was he needed someone to temporarily take over his duties as head of security on the struggling cruise ship Forever. Jack hesitates, but he owes Curt his life so agrees. He's told the worst mischief he can expect to encounter will be the occasional shoplifter, or drunk. Instead, one week into the cruise, a beautiful red head and a member of the crew are ruthlessly murdered. Are the two murders connected? It's up to Jack to find out. He must find the killer before the ship returns to Tampa's port, or worse, before another dead body is found. This won't be easy. The ship is old, it's security systems outdated, and clues are few, or so it seems at first

It's not just a sense of obligation that motivates Jack to agree to Curt's request; Jack moved thousands of miles, started over, and still can't get Amy O'Brian out of his heart or mind. When she shows up on the ship, as part of a large wedding party, Jack must fight to stay focused. To make matters worse, Amy isn't his only distraction; a sexy and mysterious woman has made it her mission to seduce Jack.

As the body count rises, and time slips away, Jack has to ask himself, "Did someone commit the perfect crime?"
