Mary Kay Andrews's The Newcomer is a sultry combination of an unsolved murder, a dangerous ex, and a complex love affair between the protagonist and head police officer. Letty Carnahan's sister is dead; but before her death, she left a scripted message and huge bag of cash with a diamond ring for her sister to find. Which begs the question, did she see her death coming? Letty takes her 4-year-old niece and hits the road, not exactly sure what or who it is she's running from.
