Will frowns thoughtfully. "If you mean by when I was able to get out of bed, it was only about a week."

He tries to think back. "Mum didn't want to talk about it much. I think it worried her. But she said I kept insisting I had lost something important. And I said some things like lines from a poem. On the day of the dead when the year too dies. On Cadfan's Way where the kestrel calls. Something like that."

He frowns."I suppose so," he says doubtfully."Perhaps I'm just being impatient. But it is a terrible feeling to constantly feel like I've just forgotten something."
