The Burglar by Thomas Perry

Elle makes a living burglarizing wealthy homes in Los Angeles. Abandoned by her family as a teen, it's the only way she knows how to survive. One day, she stumbles upon three people dead in a triple murder and is accidentally recorded at the scene. Even though she erases the footage, someone is after her and wants her dead. The Burglar recounts Elle's story as she tries to stay one step ahead of the those who want to do her harm. While I really enjoyed the first half of the story and had a hard time putting the book down, the ending was not as satifying as the set up.
