Regency widow Lily Adler is looking forward to spending the autumn away from the social whirl of London. When she arrives in Hampshire with her friends, the Carroways, she doesn’t expect much more than a quiet country visit and the chance to spend time with her charming new acquaintance, Matthew Spencer. But something odd is afoot in the small country village. A ghost has taken up residence in the Belleford manor, a lady in grey who wanders the halls at night, weeping and wailing. Half the servants have left in terror, but the family seems delighted with the notoriety that their ghost provides. Intrigued by this spectral guest, Lily and her party immediately make plans to visit Belleford. They arrive at the manor the next morning ready to be entertained–only to find that tragedy has struck. The matriarch of the family has just been found killed in her bed. The dead woman’s family is convinced that the ghost is responsible. Lily is determined to learn the truth before another victim turns up–but could she be next in line for the Great Beyond?

New York, 1924. Vivian Kelly’s days are filled with drudgery, from the tenement lodging she shares with her sister to the dress shop where she sews for hours every day. But at night, she escapes to The Nightingale, an underground dance hall where illegal liquor flows and the band plays the Charleston with reckless excitement. With a bartender willing to slip her a free glass of champagne and friends who know the owner, Vivian can lose herself in the music. No one asks where she came from or how much money she has. No one bats an eye if she flirts with men or women as long as she can keep up on the dance floor. At The Nightingale, Vivian forgets the dangers of Prohibition-era New York and finds a place that feels like home. But then she discovers a body behind the club, and those dangers come knocking. Caught in a police raid at the Nightingale, Vivian discovers that the dead man wasn’t the nameless bootlegger he first appeared. With too many people assuming she knows more about the crime than she does, Vivian finds herself caught between the dangers of New York’s underground and the world of the city’s wealthy and careless, where money can hide any sin and the lives of the poor are considered disposable…including Vivian’s own.

But anyone who might have profited from the old man’s death seems to have an alibi… until Lily receives a mysterious summons to speak with one of the Wyatts’ maids, only to find the young woman dead when she arrives. Mr. Page believes the surviving family members are hiding the key to the death of both Sir Charles and the maid. To uncover the truth, Lily must convince the father who doesn’t trust or respect her to help catch his friend’s killer before anyone else in the Wyatt household dies.
