Having narrowly escaped the electrifying machinations of Thomas Edison, Books and Braun are looking forward to a relaxing and possibly romantic voyage home. But when Braun's emergency signal goes off, all thoughts of recreation vanish. Braun's street-wise team of child informants, the Ministry Seven, is in grave peril, and Books and Braun must return to England immediately.

The Ministry has been disavowed, and the Department of Imperial Inconveniences has been called in to decommission its agents in a most deadly fashion. The plan reeks of the Maestro's dastardly scheming.
