Plot

Allied spies and Nazi Agents insinuate themselves at a Scottish cottage (converted to a wartime hospital) with interests on an inventor's nearly perfected bomb sight.

A wartime cottage on a Scottish estate becomes a focus of attention when not only the new tenant but a London evacuee and a downed fighter pilot all move in. The interest may not be unconnected with the fact that the landowner is also a key British military inventor. For a start, the butler is obviously a Scotland Yard flatfoot.—Jeremy Perkins {J-26}
