When one of her readers asks for advice following a suspected murder, Victorian countess Amelia Amesbury, who secretly pens the popular Lady Agony column, has no choice but to investigate.

Amelia Amesbury—widow, mother, and countess—has a secret. Amelia writes for a London penny paper, doling out advice on fashion, relationships, and manners under the pen name Lady Agony. But when a lady’s maid writes Amelia to ask for advice when she believes her mistress has been murdered—and then ends up a victim herself—Amelia is determined to solve the case.

With the help of her best friend and a handsome marquis, Amelia begins to piece together the puzzle, but as each new thread of inquiry ends with a different suspect, the investigation grows ever more daunting. From London’s docks and ballrooms to grand country houses, Amelia tracks a killer, putting her reputation—and her life—on the line.
