One day was spent in undergoing the most searching physical he had ever experienced. And after the doctors had poked and pried he was faced by a series of other tests no one bothered to explain. Thereafter he was introduced to solitary, that is, confined to his own company in a cell-like room with a bunk that was more comfortable than it looked and an announcer in a corner of the ceiling. So far he had been told exactly nothing. And so far he had asked no questions, stubbornly keeping up his end of what he believed to be a tug of wills. At the moment, safely alone and lying flat on his bunk he eyed the announcer, a very dangerous young man and one who refused to yield an inch.

“Now hear this . . .” The voice transmitted through that grill was metallic, but its rasp held overtones of Kelgarries’ voice. Ross’s lips tightened. He had explored every inch of the walls and knew that there was no trace of the door which had admitted him. With only his bare hands to work with he could not break out, and his only clothes were the shirt, sturdy slacks, and a pair of soft-soled moccasins that they had given him.

“ . . . to identify . . .” droned the voice. Ross realized that he must have missed something, not that it mattered. He was almost determined not to play along any more.

There was a click, signifying that Kelgarries was through braying. But the customary silence did not close in again. Instead, Ross heard a clear, sweet trilling which he vaguely associated with a bird. His acquaintance with all feathered life was limited to city sparrows and plump park pigeons, neither of which raised their voices in song, but surely those sounds were bird notes. Ross glanced from the speaker in the ceiling to the opposite wall. What he saw there made him sit up, the instant response of an alerted fighter.

The wall was no longer there! Instead, a sharp slope of ground cut down from peaks where the dark green of fir trees ran close to the snow line. Patches of snow clung to the earth in sheltered places, and the scent of those trees was in Ross’s nostrils, real as the wind touching him with its chill.
