This supplement expands the setting beyond ghosts who can take mortal form as intelligence agents. It introduces other ghosts, including housekeepers, who can interact with the living and provide useful support. It also adds mortal allies such as Professionals and Specialists, with guidance for how these characters fit into espionage operations and how to play them. Additional rules and options cover situations where a spook’s abilities are not enough.
