"I should imagine this was murder, too, because it would be very difficult to build yourself into a heap of sandbags and then die..." In the blackout conditions of a wintry London night, amateur sleuth Agnes Kinghof and a young air-raid warden have stumbled upon a corpse stowed in the walls of their street's bomb shelter. As the police begin their investigation, the night is interrupted once again when Agnes' upstairs neighbour, Mrs. Sibley is terrorised by the sight of a grisly pig's head at her fourth-floor window. With the discovery of more sinister threats mysteriously signed "Pig-sticker," Agnes and her husband, Andrew?unable to resist a good mystery?begin their investigation to deduce the identity of a villain living amongst them in their block of flats. A witty and light-hearted mystery full of intriguing period detail, this rare gem of Golden Age crime returns to print for the first time since its publication in 1943. This edition includes an Introduction by award-winning author Martin Edwards.
