Lizzy and Darcy are on their honeymoon in Bath when her mother and Kitty show up to surprise them. They have hardly recovered from that shock before they find a dead body in the women's changing room. The waters at Bath might heal, but they can't solve the mystery of who killed Lady Longe, or why they desired the cantankerous old woman's death. Lizzy and Fitzwilliam are the only ones interested enough to investigate the murder by hemlock and find answers. They have a knack for the endeavor, but Lizzy worries Fitzwilliam will lose patience with her undertaking, since it happens to be their honeymoon.
