Shann had begun contact by cleaning their cages; he ended captivated by these miniature bears with long bushy tails. And to his unbounded delight the attraction was mutual. Alone to Taggi and Togi he was a person, an important person. Those teeth, which could tear flesh into ragged strips, nipped gently at his fingers, closed without any pressure on arm, even on nose and chin in what was the ultimate caress of their kind. Since they were escape artists of no mean ability, twice he had had to track and lead them back to camp from forays of their own devising. But the second time he had been caught by Fadakar, the chief of animal control, before he could lock up the delinquents. And the memory of the resulting interview still had the power to make him flush with impotent anger. Shann's explanation had been contemptuously brushed aside, and he had been delivered an ultimatum. If his carelessness occurred again, he would be sent back on the next supply ship, to be dismissed without an official sign-off on his work record, thus locked out of even the lowest level of Survey for the rest of his life. That was why Garth Thorvald's act of the night before had made Shann brave the unknown darkness of Warlock alone when he had discovered that the test animals were gone. He had to locate and return them before Fadakar made his morning inspection; Garth Thorvald's attempt to get him into bad trouble had saved his life. Shann cowered back, striving to make his huddled body as small as possible. One of the Throg flyers appeared silently out of the misty amber of the morning sky, hovering over the silent camp. The aliens were coming in to inspect the site of their victory. And the safest place for any Terran now was as far from the vicinity of those silent domes as he could get. Shann's slight body was an asset as he wedged through the narrow mouth of a cleft and so back into the cliff wall. The climb before him he knew in part, for this was the path the wolverines had followed on their two other escapes. A few moments of tricky scrambling and he was out in a cuplike depression choked with brush covered with the purplish foliage of Warlock. On the other side of that was a small cut to a sloping hillside, giving on another valley, not as wide as that in which the camp stood, but one well provided with cover in the way of trees and high-growing bushes. A light wind pushed among the trees, and twice Shann heard the harsh, rasping call of a clak-clak--one of the bat-like leather-winged flyers that laired in pits along the cliff walls. That present snap of two-tone complaint suggested that the land was empty of strangers. For the clak-claks vociferously and loudly resented encroachment on their chosen hunting territory.
