One clue in particular hints that Edward Hyde, her father's former friend and a murderer, may be nearby, and there is a reward for information leading to his capture...a reward that would solve all of her immediate financial woes. 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.

Gower Street, London, 1882: Sidney Grice, London's most famous personal detective, is expecting a visitor. He drains his fifth pot of morning tea, and glances outside, where a young, plain woman picks her way between the piles of horse-dung towards his front door. Sidney Grice shudders. For heaven's sake - she is wearing brown shoes. The Mangle Street Murders is for those who like their crime original, atmospheric, and very, very funny.

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.

And of course Dr. John Watson is by his side (mostly) but not quite as useful as he once was.... 

London, 1875. At Lady Cornford’s famous soiree (sugared almonds and tittle-tattle) everyone is gossiping about Henry Ellis Margam’s latest hit, The Widow’s Secret. Only a few people know that one of Lady C’s guests, the enigmatic Bella Wallis, is in fact the best-selling novelist.
