"Jack-of-Smiles. The murderous buffoon, plaything of the press, and London's most notorious killer."


The only existing depiction of Jack.

Jack-of Smiles is London's most prolific murderer. He (she? it?) mostly targets humans and clay men; he has been stopped many times, but still manages to haunt the city. Perhaps because there is more than one Jack...

Who is Jack? (Spoilers for the Jack-of-Smiles Case storyline)
Jack is a set of Polythremean knives made by Mr Spices in a halfhearted attempt to create more love stories for the Bazaar through murder.
