Brian Freeman, The Night Bird

In this first of a three-book (so far?) series, San Francisco Detective Frost Easton is investigating a string of bizarre deaths. A handful of otherwise happy women have suffered violent psychotic breaks that led to their dramatic deaths. Turns out, they're all one-time patients of a psychiatrist who specializes in rewriting people's memories, and someone is tormenting her through her patients. There's scary stuff here, specifically, a guy in a creepy mask with a creepy voice—either is a problem independently, but in combination they're a nightmare. The main story is interesting, and the characters' back stories add to it. I liked Frost Easton, too. He's a cat lover with a weird living situation and a tragic past, a good anchor for a series. I think this one would make a good TV show
