Savage Magic — Lloyd Shepherd

It's 1814 and the streets of London's Covent Garden are at the centre of a dark trade, enticing rich and poor alike with a cocktail of gin and beer and sex. Behind their own fashionable private doors in the surrounding parishes a group of aristocratic young men are found murdered, all of them wearing the mask of a satyr, all of them behind locked doors with no signs of entry. Constable Charles Horton's investigation into these violent crimes begins, quite by chance, at Thorpe Lee House in Surrey, where accusations of witchcraft have swept the village. What connects these broken London men, savage with the pursuit of pleasure, and a country village awash with folklore and talk of burning witches? The answers lie, yet again, under lock and key, in a madhouse for the deranged, where Horton's wife Abigail seeks refuge from her disordered mind.
