He discovered Thorvald standing on the upper bluff, looking out toward the waiting mountains. The officer turned as Shann urged the wolverines to the raft, and when he jumped down the drop to join them, Shann saw he carried a map strip unrolled in his hand.
"The situation is not as good as we hoped," he told the younger man. "Well have to leave the river to cross the heights."
"Why?"
"There're rapids—bending in a falls." The officer squatted down, spreading out the strip and making stabs at it with a nervous finger tip. "Here we have to leave. This is all rough ground. But lying to the south there's a gap which may be a pass. This was made from an aerial survey."
Shann knew enough to realize to what extent such a guide could go wrong. Main features of the landscape would be clear enough from aloft, but there might be unsurmountable difficulties at ground level which were not distinguishable from the air. Yet Thorvald had planned this journey as if he had already explored their escape route and that it was as open and easy as a stroll down Tyr's main transport way. Why was it so necessary that they try to reach the sea? However, since he had no objection to voice except a dislike for indefinite information, Shann did not question the other's calm assumption of command, not yet, anyway.
As they embarked and worked back into the current, Shann studied his companion. Thorvald had freely listed the difficulties lying before them. Yet he did not seem in the least worried about their being able to win through to the sea—or if he was, his outer shell of unconcern remained uncracked. Before their first day together had ended, the younger Terran had learned that to Thorvald he was only another tool, to be used by the Survey officer in some project which the other believed of primary importance. And his resentment of the valuation was under control so far. He valued Thorvald's knowledge, but the other's attitude chilled and rebuffed his need for something more than a half partnership of work.
Why had Thorvald come back to Warlock in the first place? And why had it been necessary for him to risk his life—perhaps more than his life if their theory was correct concerning the Throgs' wish to capture a Terran—to get that set of maps from the plundered camp? When he had first talked of that raid, his promised loot had been supplies to fill their daily needs; there had been no mention of maps. By all signs Thorvald was engaged on some mission. And what would happen if he, Shann, suddenly stopped being the other's obedient underling and demanded a few explanations here and now?
Only Shann knew enough about men to also know that he would not get any information out of Thorvald that the latter was not ready to give, and that such a showdown, coming prematurely, would only end in his own discomfiture. He smiled wryly now, remembering his emotions when he had first seen Ragnar Thorvald months ago. As if the officer ever considered the likes, dislikes—or dreams—of one Shann Lantee. No, reality and dreams seldom approached each other. Dreams....
"On any of those shoreline maps," he asked suddenly, "do they have marked a mountain shaped like a skull?"
Thorvald thrust with his pole. "Skull?" he repeated, a little absently, as he so often did in answer to Shann's questions unless they dealt with some currently important matter.
