Portland P.I. Billie Bly doesn’t want a Facebook Page. She has no tolerance for clients who expose every movement of their day on social networks. Her assistant, Angel, convinces her she needs it as a new marketing tool since Billie’s been turning away business because of a recent depression over her brother’s death. Billie’s first Facebook client asks her to track down burglars who robbed her home when she posted about her vacation in Paris. While hunting two burglars who use Facebook to find unattended homes, Billie stumbles upon a serial killer she suspects may also using Facebook to troll for victims. Billie’s cop boyfriend won’t take her seriously, the damn killer, known as Trixie on Facebook, has friended her, and two women are kidnapped right under her nose. Now she has hours to put together the few clues her misfit team of operatives has developed and find Trixie’s victims before they are tortured and killed.
