The town of Auchnacluchnie is in a guide book with 4 ears. This makes Iain Guthrie very happy and proud this his Inn is in a very quite place. How long will it last? Now that Nuclear Command Bunker no. K553/44FS has a new siren alarm ordered by Flight Lieutenant Harrison. Will the fact North Korean made alarm make the Wing-Commander happy? Will Tench and Harrison install correctly? Will there peace and quiet in Auchnacluchnie?
