A group of foreign delegates visiting a fog-bound London for an international disarmament conference are lured to their deaths by a killer imitating the Victorian mass murderer, the Gaslight Ghoul. Never caught, the ghoul has inspired a number of professional men to start their own Gaslight Ghoul club, one of whom aims is to unmask the original killer. Steed joins the club to discover the identity of the latter-day culprit.
