The Highway curved between great looming walls of cragged old rock, a shadow tunnel with the wind yowling far overhead and the sun a disc of blood. Men's footfalls echoed from the cracked paving blocks to boom hollowly off time-gnawed cliffs and ring faintly in the ice. It was cold, their breath smoked from them and they shivered and cursed and stamped their feet. Donovan walked beside Helena, who was riding Wocha. His eyes narrowed against the searching wind, looking ahead and around, looking for the side track where the ambush waited. Drogobych was very near. Something moved up on the ridge, a flapping black thing which was instantly lost to sight. The Arzunians were watching. There--up ahead--the solitary tree they had spoken of, growing out between age-crumbled fragments of the road. The highway swung west around a pinnacle of rock, but here there was a branch road running straight south into a narrow ravine. _All I have to do is suggest we take it. They won't know till too late that it leads up a blind canyon._ Helena leaned over toward him, so that the long wind-whipped hair blew against his cheek. "Which way should we go?" she asked. One hand rested on his shoulder. He didn't slacken his stride, but his voice was low under the whine of bitter air: "To the right, Helena, and on the double. The Arzunians are waiting up the other road, but Drogobych is just beyond that crag." "Basil! How do you know--" Wocha's long hairy ears cocked attentively, and the little eyes under the heavy bone ridges were suddenly sharp on his master. "They wanted me to mislead you. I didn't say anything before for fear they'd be listening, somehow." _Because I hadn't decided_, he thought grayly. _Because Valduma is mad, and I love her._ Helena turned and lifted her arm, voice ringing out to rattle in jeering echoes: "Column right! Forward--charge!" Wocha broke into a trot, the ground booming and shivering under his huge feet. Donovan paced beside, drawing his sword and swinging it naked in one hand, his eyes turned to the canyon and the rocks above it. The humans fell into a jogging run. They swept past the ambush road, and suddenly Valduma was on the ridge above them, tall and slim and beautiful, the hair like a blowing flame under her helmet. "Basil!" she screamed. "Basil, you triple traitor--" The others were there with her, men of Drogobych standing on the heights and howling their fury. They had chains in their hands, and suddenly the air was thick with flying links. One of them smashed against Donovan and curled itself snake-like around his waist. He dropped his sword and tugged at the cold iron, feeling the breath strained out of him, cursing with the pain of it. Wocha reached down a hand and peeled the chain off, snapping it in two and hurling it back at the Arzunians. It whipped in the air, lashing itself across his face, and he bellowed.
