When Kate Rosetti returns from a rare week of vacation in Hawaii, she finds herself immediately immersed in a case more complicated than any she's faced before. A man's body has been stuffed into the back of an ice-cream truck, and it seems like everyone—including his three girlfriends—had a reason to kill him. But when the case blows up into a bigger sensation than Kate could ever have anticipated, she finds herself forced to work side by side with her ex-boyfriend, FBI Agent Jack Russo...and his very new, very attractive female partner. As Kate closes in on a murderer who is quickly racking up a tally of bodies, she realizes she must catch this killer or someone she loves might be dead next.
