Guy met the local boys a week after his arrival....On the first day off, when Tolik did not have to go to the laboratory, they went to Chersonesos. We wandered among the gray walls and towers, among the buried and overgrown ancient quarters, among the columns of ruined temples, along yellow rocky cliffs and rocky beaches, where the waves rolled large pebbles. Tolik then grabbed Guy by the shirt when he tried to dive into the black hole of the dungeon or climb along the plumb line of the tower, then he would hurry up if he froze for a long time above a lurking crab or a flat stone with half-erased incomprehensible letters.
