Lady Georgiana “Georgie” Rannoch is just like any other new mother, balancing responsibilities such as being 34th in line for the British throne and solving the mysterious deaths of several young men, in the newest case from the queen of historical mystery, Rhys Bowen.

Georgie may not have much in common with your average new mother, but she does have one thing: a new nanny she despises. Knowing she must find a nanny more suited to her young son, Georgie travels to London to see her old friend ZouZou, only to find her about to depart for a funeral, after the unexpected death of a young man. It quickly becomes clear there’s more than one mysterious death around town, when another friend, Georgie Gormsley, reveals he’s just returned from the funeral of a school friend, who seemingly drowned while swimming. And then Georgie's best friend, Belinda, receives a telegram informing her that the son of family friends has died tragically. It begins to seem like too much of a coincidence to Georgie. Yet the victims didn’t seem to have any connection to one another.

Georgie returns to ZouZou, who puts the final nail in the coffin—she’s sure that the deaths were not an accident and begs Georgie to solve the case. As Georgie begins investigating, she can’t help worrying that her own husband, Darcy, may be next. She begins to suspect there might be a serial killer at work and as she delves deeper into the case, realizes that the young men may all share a link to a crime many years ago. Will Georgie solve the murders before it’s too late for Darcy, and manage to find the perfect nanny all at the same time?
