My mother cried out: “Let him go! If you hurt him, Vortigern, king or no king, I will never tell you, even if you kill me. Do you think I held the truth from my own father and my brother and even from my son for all these years, just to tell for the asking?”

“You will tell me for your son’s sake,” said Vortigern. At his nod the fellow took his hand from my mouth, and stood back. But his hand was still on my arm, and I could feel the other’s sword sharp through my tunic.

My mother had thrown back her hood now, and was sitting upright in her chair, her hands gripping the arms. Pale and shaken as she was, and dressed in the humble brown robe, she made the Queen look like a servant. The silence in the hall now was deathly. Behind the King’s chair the priests stood staring. I held tightly to my thoughts. If these men were priests and magicians, then no thought of Ambrosius, not even his name, must come into my mind. I felt the sweat start on my body, and my thoughts tried to reach my mother and hold her, without forming an image which these men could see. But the power had gone, and there was no help here from the god; I did not even know if I was man enough for what might happen after she told them. I dared not speak again; I was afraid that if they used force against me she would speak to save me. And once they knew, once they started to question me . . .

Something must have reached her, because she turned and looked at me again, moving her shoulders under the rough robe as if she felt a hand touch her. As her eyes met mine I knew that this was nothing to do with power. She was trying, as women will, to tell me something with her eyes. It was a message of love and reassurance, but on a human level, and I could not understand it.

She turned back to Vortigern. “You choose a strange place for your questions, King. Do you really expect me to speak of these things here, in your open hall, and in the hearing of all comers?”

He brooded for a moment, his brows down over his eyes. There was sweat on his face, and I saw his hands twitch on the arms of the chair. The man was humming like a harp-string. The tension ran right through the hall, almost visibly. I felt my skin prickle, and a cold wolfspaw of fear walked up my spine. Behind the King one of the priests leaned forward and whispered. Then the King nodded. “The people shall leave us. But the priests and the magicians must remain.”
