“How so?” asked Tristan, growing the keener as he listened.

Ogier edged his horse round a fallen tree.

“Before Lententide,” he said, slouching lazily in the saddle, “I was sent by ship with certain priests to a northern province to treat with Blanche the Bold, who is a duchess there. Ha, but she would have none of our treaties. Sailing home with a good west wind, we ran by an island—Purple Isle, as my sea-dogs said, far out to sea. Our casks were low, so we landed to win water. By a spring near the shore my fellows caught a chit of a girl with as pert a face and as trim a body as I ever saw in Agravale. ‘So ho,’ thought I, ‘here is good merchandise to please the Bishop.’ Ha, brother, but I sold her to Jocelyn for two hundred silver crowns.”

Tristan, with a sudden grimness in his eyes, twitched at his bridle and drew a yard nearer to the man on the white stallion. So tightly were Tristan’s lips pressed together that they formed a pouting line above his chin. The muscles were knotted about the angle of his jaw. He would not trust his tongue for the moment, lest the truth should out.

“A good bargain, comrade,” he said, grinding his teeth, every sinew of him taut as the fibres of a wind-rocked tree, “a good bargain. And the girl, what of her?”

Ogier laughed. His great red mouth gaped above his beard, and there was an unclean glint in his wolfish eyes.

“She was good food,” he said. “I had my fill before she came to the Bishop’s table. Bah! we soldiers have our turn.”

Tristan’s hand was on his sword. The muscles of his arm tightened, then relaxed. He shut his eyes for the moment, saw blood against the sun. Yet, from mere molten wrath, his vengeance hardened to metal at white heat.

“What of the girl?” he asked again.

Ogier puffed out a deep breath, wiped his mouth on the back of his hand.
