An invitation. A ghostly spectre. A criminal mastermind.

When Holmes and Watson are invited to visit an old friend of the pipe-smoking detective, they are plunged into the first of three adventures involving the Dark Arts and the supernatural. From the ghostly spectre of a dead sister to the search for an ancient book of spells, the detecting duo learn that each case is connected, leading them into a final showdown with their deadliest adversary yet.

Adult humour throughout.

'The Watson Letters – Volume 6: The Haunting of Roderick Usher' is book #6 in this Victorian comedy adventure series set in a not quite Post-Victorian, steampunk parallel universe.

If you love historical mysteries, buy something else instead, but if you're into murder, fart-gags and innuendo, this'll be right up your Victorian street.
