In the eight-page story, Agatha, aided by Krosp, is doing the "Lady Adventurer" thing, tracking down problems and trying to fix them. She has come across the activities of a gang of "rogue constructs" — Zon, Garon, Luilla, and Torsti Lechwa, whose creators have died or abandoned them. They are surviving by working as confidence artists, and the "Electric Coffin" of the title is an integral part of their audacious plan to avoid detection and pursuit. The end of the story portends some interesting developments for Agatha's future career.
