Murdoch takes little interest in the sightings of the cloaked, masked 'Lurker', who keeps popping up in a nearby quarter and surprises implicitly flattered ladies including Crabtree's Nina's cabaret staff, while their men cry scandal, one fiance even demands a hanging. Thomas's return from St. Louis with the triumphant world champion team takes first seat, even William is sidetracked in favor of the inspector's travel and pub companion, rich inventor James Pendrick. Later the Lurker becomes prime suspect for the murder of a catering 'saucage king' without enemies and the robbery from Pendrick's new lab of his Panamanian wonder drug, which he had smuggled in by Brackenreid and proves key to a Jeckyll and Hyde twist.
