At First Sight by Stephen J. Cannell
The subtitle on this new (and non-Detective Sully) novel from Cannell is "A Novel of Obsession", which perfects sums up this new suspense read.
Chick Best is an LA-livin', Porsche driving, internet mogul, well, jackass, who has a trophy wife and a daughter who hates him. He's resigned to spending a miserable Christmas in Maui with his hateful wife and daughter...until he spots Paige Ellis at the pool one day.
What follows is Chick's growing obsession with Paige, which eventually leads to murder...
This is one of those "car wreck" books - you know it's going to end badly, but you can't look away! Chick is really a despicable character, and yet, you can't help but wonder how he's going to get himself out of his dangerous situation. Paige is a lovely character, and when it switches to her point of view, it feels like a breath of normalcy in the story.
This has all the hallmarks of a Cannell novel - great character development, fast-paced plot, a few snickering moments, and a satisfying conclusion. Recommended!
Note: I listened to the audio version, narrated by Scott Brick. I heart the Brickster.
