Suspiciously inconspicuous disappearance

March 1941. Britain is at war and the Ministry of Unladylike Activity has begun training children as agents. Among the new recruits are our three fearless and cunning heroes: May, Eric, and Nuala. In the cellar of a house damaged by a bomb, they make a gruesome discovery – a dead body. A body that wasn't there after the air raid that destroyed the house. Could it belong to the ministry's missing agent? Or someone else entirely – perhaps one of the residents of the little street, whom someone tried to silence?
