The Wicked Cometh will take readers on a heart-racing journey through backstreets swathed with fog to richly curtained, brightly lit country houses; from the libraries and colleges of gentlemen, to sawdust-strewn gin palaces where ne'er-do-wells drink and scheme, all told through the eyes of a heroine with nothing to lose.

The year is 1831.

Down murky alleyways and in filthy hovels, acts of unspeakable wickedness take place and vulnerable people begin to disappear from the streets. Out of these shadows comes Hester White, a young woman who is desperate to escape the slums by any means possible.

When Hester is thrust into the world of the aristocratic Brock family, she leaps at the chance to improve her station in life under the tutelage of the mysterious Rebekah Brock. But both she and Rebekah are lured into the most sinister of investigations as whispers from Hester's old life return to poison the present. Something is lurking in the black heart of their city, and it is more depraved than either of them could ever imagine . . .
