March 1941. Britain is at war, and a secret agency called the Ministry of Unladylike Activity is training up children as spies - because grown-ups always underestimate them. Enter May, Eric and Nuala: courageous, smart, and the Ministry's newest recruits. They have travelled to London for spy training, and are staying on a quiet street close to the Ministry, home to an unlikely collection of people thrown together by the war. One day, while exploring the bombed-out house at the end of the street, they discover something that should not be there. Something that was not there when the Blitz wreckage was first combed through. Something that has been placed there recently. A body... Could this be the missing Ministry spy that Daisy Wells is on a dangerous mission in France to find? Or could it be someone else - someone a resident of the street wanted silenced . . . ?
