The other was a wrecked gun safe standing against the wall in the corner of the loft. Something comprehensively bad had happened to it. Its finish had been burned away in a line that went all the way around its top, as though it had been attacked with a thermonuclear can opener. The entire top of the safe had been sliced off and thrown on the floor, where hot metal edges had burned into the wood. Instinctively Richard scanned the ceiling for smoke detectors and noted that they were all dangling open, their batteries removed.
