In the sordid streets of Victorian London, unwanted desire flares between two bitter enemies brought together by a deadly secret.
Crusading journalist Nathaniel Roy is determined to expose spiritualists who exploit the grief of bereaved and vulnerable people. First on his list is the so-called Seer of London, Justin Lazarus. Nathaniel expects him to be a cheap, heartless fraud. He doesn’t expect to meet a man with a sinful smile and the eyes of a fallen angel—or that a shameless swindler will spark his desires for the first time in years.
But Justin and Nathaniel are linked by more than their fast-growing obsession with one another. They are both caught up in an aristocratic family’s secrets, and Justin holds information that could be lethal. As killers, fanatics, and fog close in, Nathaniel is the only man Justin can trust—and, perhaps, the only man he could love.
