The second thrilling adventure in the new World War Two mystery series from the million-copy-bestselling author of Murder Most Unladylike.

'Robin Stevens is Agatha Christie for children' Katherine Rundell

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: brave, smart, and the Ministry's newest recruits.

May's big sister Hazel has arranged for them to stay on a quiet street close to the Ministry. And it is in the bombed-out house at the end of that street that they discover something mysterious. Something that was not there when the Blitz wreckage was first combed through. 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 . . . ?
