"While Ellie's away, murder will play . . . Is the death of Ellie's son-in-law really the result of a burglary gone wrong?

Is Evan's death really the result of a burglary gone wrong? Joining forces with her aunt, police officer Lesley Millard, Susan discovers that Diana lied to the police about her movements on the night of the murder, and soon finds herself grappling with betrayal, shady business dealings and her own distrust of Diana as she attempts to solve a chilling conundrum: could Ellie's daughter be a cold-blooded killer?"--Publisher description
