From the description:
"Abby Sinclair deals in risk assessment—but it’s lives, not fortunes, that are at stake. The Los Angeles investigator goes undercover to figure out whether a client’s stalker is simply an overzealous fan or a dangerous psychopath. She’s learned the hard way that the difference isn’t always apparent until it’s too late. In Raymond Hickle’s case, however, Abby has no doubts.
The awkward loner’s fixation with gorgeous news anchor Kris Barwood has progressed from creepy to murderous. So Abby befriends Hickle, trying to gauge when and how he’ll strike. Yet her target is as wily as he is unhinged, and Abby has unwittingly made herself a madman’s latest obsession. With her reputation and life on the line, Abby races to save Kris before Hickle eliminates them both."
