At last Sansum went and Igraine made a face at his retreating back. ‘Tell me, Derfel,’ she said when the saint was out of earshot, ‘what should I do for the birth?’

‘Why on earth do you ask me?’ I said in amazement. ‘I know nothing about childbirth, thank God! I’ve never even seen a child born, and I don’t want to.’

‘But you know about the old things,’ she said urgently, ‘that’s what I mean.’

‘The women in your caer will know much more than I do,’ I said, ‘but whenever Ceinwyn gave birth we always made sure there was iron in the bed, women’s urine on the doorstep, mugwort on the fire, and, of course, we had a virgin girl ready to lift the newborn child from the birth-straw. Most important of all,’ I went on sternly, ‘there must be no men in the room. Nothing brings so much ill-luck as having a man present at a birth.’ I touched the protruding nail in my writing desk to avert the evil fortune of even mentioning such an unlucky circumstance. We Christians, of course, do not believe that touching iron will affect any fortune, whether evil or good, but the nailhead on my desk is still much polished by my touching. ‘Is it true about the Saxons?’ I asked.

Igraine nodded. ‘They’re getting closer, Derfel.’

I rubbed the nailhead again. ‘Then warn your husband to have sharp spears.’

‘He needs no warning,’ she said grimly.

I wonder if the war will ever end. For as long as I have lived the Britons have fought the Saxons, and though we did win one great victory over them, in the years since that victory we have seen more land lost and, with the land, the stories that were attached to the valleys and hilltops have been lost as well. History is not just a tale of men’s making, but is a thing tied to the land. We call a hill by the name of a hero who died there, or name a river after a princess who fled beside its banks, and when the old names vanish, the stories go with them and the new names carry no reminder of the past. The Sais take our land and our history. They spread like a contagion, and we no longer have Arthur to protect us. Arthur, scourge of the Sais, Lord of Britain and the man whose love hurt him more than any wound from sword or spear. How I do miss Arthur.
