There was the upflashing of a sword, and a hoarse challenge startled the trees.

“Guard, devil, guard!”

Ogier, his great mouth wide, twisted round, saw a furious face glaring dead white front under the shadow of a shield. A sword streaked the sunlight. Ogier blinked at Tristan as at one gone mad.

“Damnation! What’s amiss, my son?”

“By the love of God, I have you now!”

“Fool, are you mad?”

The hoarse voice echoed him; the eyes flashed fire.

“Guard, ravisher, guard!”

“Ten thousand devils! What have we here?”

“Tristan of Purple Isle, avenger of Columbe; Tristan the Heretic, Tristan of the Seven Streams.”
