Set in the same 1850s London society that gave rise to Jack the Ripper, this British detective drama features a fearless, independent heroine played by Kate Phillips (Peaky Blinders). With her inquisitive mind, Miss Eliza Scarlet has always been more interested in running her late father's detective agency than behaving like a proper lady, much to the chagrin of family friend Inspector William Wellington of Scotland Yard (Stuart Martin, Jamestown), also known as The Duke. But nothing has prepared her for the dangers she is about to face as a woman in the murder investigation trade.
