In the shadowy depths of 1819 London, journalist Ezra Geldart leads a double life alongside his aristocratic cousin, Lord Cameron Sinclair, as they excavate the bodies for the surgeon Mr. Bennett. On his birthday – a day meant for celebration – a surprise invitation brings Ezra's estranged twin sister, Eliza, back into his life, just as the air around them thickens with tension.

At Lady Griswold and Bartholomew's engagement ball, unspoken feelings smolder beneath finery and laughter.

As the cousins dig deeper into the remains of London’s secrets, Eliza stumbles upon Ezra's hidden truth, igniting her curiosity and joining the macabre job as a decoy.

However, as revelations unfold, ambitions darken. Bartholomew’s infatuation with Eliza turns obsessive, leading him to unleash a determined pursuit that tests the bonds of family and friendship. As their lives unravel, the siblings must navigate the murky waters of love, ambition, and betrayal. Can Ezra and Eliza unearth the skeletons of their past—and survive Bartholomew's relentless obsession—before it consumes them all?
