She isn't sure whether to believe the man now and if so, who really killed her father? As she investigates the case of the missing mom, she begins to unravel a bigger mystery. The number of missing people could number in the dozens and they all seem to be connected to the one dating web site.

He confesses to her that it was an accident and that was the reason he left eighteen years ago. As the book ends, the two of them are sitting on the bed, waiting for the next step.
Best part of story, including ending:
The two intertwined cases were very surprising and in both cases, the villains weren't apparent until the very end. That made it a very enjoyable and unpredictable read.
Best scene in story:
The final scene, in which a horrified Kat discovers that her second chance at romance isn't happening, now that she's discovered the identity of her father's killer.
Opinion about the main character:
Kat Donovan might be a great cop, but she struggles in her personal life. And those struggles make her a better policeman and a more interesting character to read.
