had been blanketed out. The ground was white. The sea was white. It was difficult to tell where one ended and the other began, and standing in the fields you felt like a single letter on a blank page in an envelope waiting to be posted.
There was no central heating at Groosham Grange. Instead, huge logs burned in open fireplaces, crackling and hissing as if they were angry at having to share their warmth. All the windows had steamed up and the plumbing shuddered, groaned and gurgled as the water forced its way through half-frozen pipes. A colony of bats that inhabited one of the northern towers migrated downstairs for warmth and ended up in the dining-room. Nobody complained. But David found mealtimes something of a struggle with about a hundred eyes examining his rhubarb crumble upside down from the rafters.
Apart from the bats and the weather, nothing else had changed at the school. At first David had been surprised that nobody seemed to care about Christmas. Later on he had glumly accepted it. Captain Bloodbath came to the school once a week, on Tuesdays, but he never brought any letters or took any so there were no Christmas cards. There were no Christmas decorations either. David had seen Mrs Windergast with an armful of holly and that had raised his spirits – at least until lunchtime, when he had had his first taste of holly soup. There was no Christmas tree and, of course, no Christmas presents. Despite the snow, nobody threw any snowballs and the only snowman turned out to be Gregor, who had dozed off on his gravestone just before the heaviest fall and had to be thawed out the next day.
Only one teacher even mentioned Christmas, and this was Mr Creer in religious studies. Mr Creer was the only normal-looking teacher in the whole school. He was the youngest too, about thirty, short with curly hair and a neat moustache. His full name was Ronald Edward Creer. David had been a little unsettled to see the same name on a tombstone in the school cemetery – “Drowned off Skrull Island: 1955-1985” – but he had assumed it was a relative. Nonetheless, Mr Creer did smell very strongly of seaweed.
“Christmas, of course, has very little to do with Christianity.” Mr Creer gave the class a ghostly smile. All his smiles were rather ghostly. “There were festivals at the end of December long before Christianity appeared; the Roman ‘Saturnalia’ and the Persian ‘Birth of the Sun’, for example. In the north it is a festival of the dark spirits, for it is at Christmas that the dead return from their graves.”
This was all news to David. But he had to admit that living in London and being surrounded by tinsel, department-store Santas, last-minute shopping, mince pies, puddings and too many old films on TV, Christmas had never had much to do with Christianity there either.
Christmas Day began like any other day: baths, breakfast, three lessons, then lunch. For some reason, however, the lessons in the afternoon had been cancelled and David and Jill found themselves free to wander as they pleased. As usual, all the other pupils went to bed. That was what they did whenever they had any free time. Then, late at night, they would go to the library. And then they would disappear.
David and Jill had tried to follow them several times, determined to get to the bottom of the mystery, but without success. The trouble was that there was no way they could follow the others into the library without being seen, and by the time they opened the door everyone had gone. One afternoon they searched the room thoroughly, certain that there must be a secret passage. But if there was a secret passage, it must have had a spectacularly secret entrance. All the walls seemed to be made of solid brick. A fireplace with a stone mantelpiece dominated one of them, and there was a full-length mirror in a frame decorated with bronze flowers on the other. But though David pressed and prodded all the animals while Jill fiddled with the mirror and
