8:00 p.m.
Mallory , who among other things was a time-thief , re-materialized the time-space boat _ Yore _ in the eastern section of a secluded valley in ancient Britain and typed CASTLE , EARLY SIXTH-CENTURY on the lumillusion panel . Then he stepped over to the control-room telewindow and studied the three-dimensional screen . The hour was 8:00 p.m. ; the season , summer ; the Year 542 A.D. Darkness was on hand , but there was a full moon rising and he could see trees not far away -- oaks and beeches , mostly . Roving the eye of the camera , he saw more trees of the same species . The `` castle of Yore '' was safely ensconced in a forest . Satisfied , he turned away .
