Following a whirlwind engagement to Viscount "Lyndy" Lyndhurst, Stella Kendrick is finding her footing within an elite social circle in picturesque rural England. Except tea time with refined friends can be more dangerous than etiquette faux pas–especially in the company of Lady Philippa, the woman Lyndy was once set to marry, and her husband, the ostentatious Lord Fairbrother …

Outrage erupts and accusations fly after Lord Fairbrother's pony wins best in breed for the seventh consecutive year. The man has his share of secrets and adversaries, but Stella and Lyndy are in for a brutal shock when they discover his body floating in the river during a quiet morning fishing trip …

Suddenly unwelcome around hardly-grieving Lady Philippa and Lyndy's endlessly critical mother, Stella faces the bitter reality that she may always be an outsider–and one of her trusted new acquaintances may be a calculating killer. Now, Stella and her fiance must fight against the current to catch the culprit, before they're the next couple torn apart by tragedy.
