Brian was trying extremely hard to go to sleep, which, as anybody who has attempted it will tell you, is the most reliable method ever discovered for staying wide awake. He had tried lying still. He had tried counting, and squeezing both eyes shut and being asleep as hard as it is humanly possible to be asleep. Now he lay on his back, staring at the ceiling, as wide awake as a person can be.
And then, at the precise moment Bramble the elf did up the last buckle, something went SNAP. The small silver bell at the very front of the harness came off, bounced twice, and went away down a chute into the building, ringing merrily the whole way, which nobody found nearly as charming as it sounded.
So Brian used his eyes instead, spotted a flash of silver under a bench, and went for it flat out. And he would have had it. He genuinely would have had it. But a rocking horse came swinging past at the very worst moment available, caught the bell on its runner and flicked it up onto a belt carrying boxes to the floor above. Rocking horses have no idea what they are doing. That is rather the trouble with them.
And there, rolling along a bench and minding its own business, was the bell. Brian got both hands round it and held on with everything he had. He had it. He actually, definitely, finally had it. And then a long ribbon of green and pink light came curling past, plucked the bell straight out of his hands, and swept Brian away with it, up through the hatch and out into the sky.
So Brian turned round and ran the other way. Down the ladder, along the deck, all the way back to the sleigh, and got there first, and stood at the harness with the empty strap held up in both hands, breathing hard, waiting. And the bell came down off that roof and arrived like it had been meaning to all along. CLICK. ‘How did you ever get it back?’ said Santa. ‘I stopped chasing it,’ said Brian.
‘Well then,’ said Santa. ‘You had better get in.’ So Brian climbed up beside him, and eight reindeer leaned into the harness at exactly the same moment, and the whole enormous sleigh came up off the deck as though it weighed nothing, up over the roofs and over the cloud, with every bell on that harness ringing together at last, and the whole sky behind them hung with green and pink.
