After her bruising encounter with the law, Angela Marchmont has vowed to give up detecting, and is doing her best to forget the events of last winter and the terrible lie she told to save herself. So when a letter arrives from beyond the grave requesting her help and reminding her of the past, she is anything but pleased. Drawn reluctantly into one final case and spurred on by her guilty conscience, Angela soon discovers a viper's nest of family betrayals and hidden enmities which have lain undisturbed for years, and which may have led to the deaths of more than one person. Despite her unwillingness to reopen old wounds, Angela knows she must put aside her own feelings and solve the mystery if she is ever to find peace. Can she get to the heart of the matter, right the wrong she has done and be happy at last?
