1898. Quinn le Blanc, London’s most talented con woman, has five days to pull off her most ambitious plot yet: trap a highly eligible duke into marriage and lift a fortune from the richest family in England. Masquerading as the season’s most enviable debutante, Quinn puts on a brilliant act that earns her entrance into the grand drawing rooms and lavish balls of high society --- and propels her straight into the inner circle of her target: the charismatic Kendals. Among those she must convince are the handsome bachelor heir, the rebellious younger sister, and the esteemed duchess eager to see her son married. But the deeper she forges into their world, the more Quinn finds herself tangled in a complicated web of love, lies and loyalty. The Kendals all have secrets of their own, and she may not be the only one playing a game of high deception.

Mrs. King is no ordinary housekeeper. Born into a world of con artists and thieves, she’s made herself respectable, running the grandest home in Mayfair. The place is packed with treasures, a glittering symbol of wealth and power, but dark secrets lurk in the shadows. When Mrs. King is suddenly dismissed from her position, she recruits an eclectic group of women to join her in revenge. Their plan? On the night of the house’s highly anticipated costume ball --- set to be the most illustrious of the year --- they will rob it of its every possession, right under the noses of the distinguished guests and their elusive heiress host. But there’s one thing Mrs. King wants even more than money: the truth. And she’ll run any risk to get it.
