A Cold Day in Hell by Lissa Marie Redmond

Lauren Riley is an accomplished detective who has always been on the opposite side of the courtroom from her nemesis, slick defense attorney Frank Violanti. But now he’s begging to hire her as a private investigator to help clear his client of murder. At first Lauren refuses, wanting nothing to do with the media circus surrounding that case—until she meets the eighteen-year-old suspect.

To keep an innocent teen from life in prison, Lauren must unravel the conflicting evidence and changing stories to get at the buried facts. But the more she digs, the more she discovers that nothing is what it first appears to be. As Lauren puts her career and life in danger, doubt starts to lurk on every corner . . . and so does her stalker.
