It also could be revenge.But hardened cop Frank Zimmerman doesn't believe in coincidences.A drowned lawyer, a fatal car accident, a heart attack and a socialite's lethal fall in front of a huge crowd all have his cop antennae pinging - hard.He digs for evidence to support his theory of a trail of bodies that lead into the past.What's going on? And who will die next?
