Poppy receives the gift of a London Season from her distant father; he hopes she might make a suitable match. Although she would prefer to spend time with her beau, Sergeant Dyngley, Poppy's uncle will only agree if she also sees the odious Mr. Terrence Terrell.

Henry Dyngley is thrilled to be promoted to Sergeant. As a favor to the judge who arranged his promotion, he agrees to escort the man's daughter for the Season. But he soon learns the judge's family has chosen him as a desirable son-in-law and will do anything to achieve this, regardless of what feelings Henry may have for another girl.

In London, Poppy's new debutante friends are surrounded by scandal due to a past incident that left one man dead. Now they are stalked by suitors who want answers, and someone has decided that only death will right a past wrong.

One of Poppy's new friends begs her to help find the culprit. But if Poppy is to succeed, she will have to decide: are they innocent friends or deadly debutantes?

Can Poppy find the killer in time? Will she and Sergeant Dyngley ever be together, or will she be forced to marry Mr. Terrell?
