"I can throw this ship into orbit around the asteroid. We can go down there and settle the thing between us. The winner can jump up here again with the help of a jet of tanked air. The lump hasn't got much gravity."

Lundgard hesitated. "And how do I know you'll keep your end of the bargain?" he asked. "You could let me go through the airlock, then close it and blast off."

Bo had had some such thought, but he might have known it wouldn't work. "What do you suggest?" he countered, never taking his eyes off the planetoid. "Remember, I don't trust you either."

Lundgard laughed suddenly, a hard yelping bark. "I know! Valeria, go aft and remove all the control-rod links and spares. Bring them back here. I'll go out first, taking half of them with me, and Bo can follow with the other half. He'll have to."

"I—no! I won't," she whispered. "I can't let you—"

"Go ahead and do it," said Bo. He felt a sudden vast weariness. "It's the only way we can break this deadlock."

She wept as she went toward the engine room.

Lundgard's thought was good. Without linked control-rods, the converter couldn't operate five minutes, it would flare up and melt itself and kill everyone aboard in a flood of radiation. Whoever won the duel could quickly re-install the necessary parts.

There was a waiting silence. At last Lundgard said, almost abstractedly: "Holmgang. Do you know what that means, Bo?"

"No."
