Guy got acquainted with the local boys a week after arriving.
… On the first day off, when Tolik did not need to go to the laboratory, they went to Chersonesus. They wandered among gray walls and towers, among buried and overgrown ancient quarters, among the columns of ruined temples, along yellow rocky cliffs and stony beaches where the waves rolled large pebbles.
Tolik would either grab Guy by the shirt when he tried to dive into the black opening of an underground passage or climb the sheer wall of a tower, or urge him on if he lingered too long over a hidden crab or a flat stone with half-erased incomprehensible letters.
