But her hunt leads her to Hyde's daughter, Diana, a feral child left to be raised by nuns.

The year is 1895. The police don't have the resources to deal with everything that goes on in the capital. The rich turn to a celebrated private detective when they need help: Sherlock Holmes. But in densely populated South London, where crimes are sleazier and Holmes rarely visits, people turn to Arrowood, a private investigator who despises Holmes, his wealthy clientele and his showy forensic approach to crime. Arrowood understands people, not clues.

A weekly newspaper dedicated to the weird and the wonderful (but mostly the weird), The Stranger Times is the go-to publication for the unexplained and inexplicable. At least that's their pitch. The reality is rather less auspicious. Their editor is a drunken, foul-tempered and foul-mouthed husk of a man who thinks little of the publication he edits. His staff are a ragtag group of misfits. And as for the assistant editor...well, that job is a revolving door - and it has just revolved to reveal Hannah Willis, who's got problems of her own.

Yet hidden away in a barely used top-floor room, she finds he had secretly kept a cupboard full of her possessions. Sifting through the ancient papers, Ruth discovers the diary and letters written by her ancestor from the 18th century, Thomas Erskine.

Odin has a challenge for Conrad: Sign up to protect England from wild magick and get a commission in the King’s Watch. All he has to do is find a missing witch.
