England, 1925. After years shut away from the world, former detective Lord Edgington of Cranley Hall plans a grand ball to celebrate his seventy-fifth birthday. But when someone starts bumping off members of his scheming family, the old man enlists his teenage grandson to help find the killer, before one of them is next.

Determined to support her mother and sisters after her father's untimely death, Charlotte Mandeville covertly crafts satirical caricatures of high society. It not only puts money in her family’s bare pockets, but ensures the haut-ton cannot guard all the power and the secrets. Anthony Yorke has a guilty conscience and a brother to exonerate. When the key piece of evidence to clear his brother's name falls into the hands of a headstrong young woman, he is willing to do whatever is required to obtain it from her.

At twenty-two, Rosalie Harrow is unmarried and near destitute. She has two choices: snag a wealthy gentleman, or take work as a governess. Neither option appeals to headstrong Rosalie. When Rosalie receives an invitation to Alcott Hall, she believes she's there to meet the Dowager Duchess of Norland. Instead, Rosalie is thrust in the middle of a house party of eligible high society ladies all desperate to win the hand of the new, conveniently single duke.

Hours later, the man’s cold body lies in the city mortuary, alongside the woman he couldn’t save. And his sister, unconventional nurse Gemma Tate, tracks down troubled police inspector Sebastian Bell to unravel the truth. Sebastian has enough pressure to solve the murder of an aristocratic heiress without Gemma meddling in his case. But the cryptic sentences she brings him from her brother’s notebook could be a crucial lead. If only they knew what “milky way” meant.

The Halifax Hellions are the most scandalous, outrageous, ungovernable ladies in London. From the day of their debut—in which Matilda smoked a cheroot and Margo tied a cherry stem in a knot with her tongue—they’ve turned the ton upside down. But when Matilda elopes with a dangerous aristocrat, Margo must stop her twin before this new misadventure becomes a permanent marriage. For help, Margo turns to her brother’s best friend—because if anyone can get them to Scotland in time, it’s starchy solicitor Henry Mortimer.
