Moonraker

The two thirty-eights roared simultaneously. The walls of the underground room took the crash of sound and batted it to and fro between them until there was silence. James Bond watched the smoke being sucked from each end of the room towards the central Ventaxia fan.

He broke the chamber sideways out of the Colt Detective Special and waited, his gun pointing at the floor, while the Instructor walked the twenty yards towards him through the half-light of the gallery.
