But Tugh was unhurt; he seemed endowed with superhuman strength. The cripple's body seemed padded with solid muscle, and his thick, gorilla-like arm held Larry in the grip of a vise. As though Larry and Tina were struggling, helpless children, he was half dragging, half carrying them across the ten-foot width of the catwalk.
Larry caught a glimpse of a narrow slit in the masonry of the dam's wall—a dark, two-foot-wide aperture. He felt himself being shoved toward it. For all his struggles, he was helpless. He shouted:
"Tina—look out! Break away!"
e forgot himself for a moment, striving to wrest her away from Tugh and push her aside. But the strength of the cripple was monstrous: Larry had no possible chance of coping with it. The slit in the wall was at hand—a dark abyss down into the interior of the dam. Larry heard the cripple's words, vehement, unhurried, as though with all this effort he still was not out of breath:
"At last I can dispose of you two. I do not need you any longer."
Larry made a last wild jab with his fist into Tugh's face and tried to twist himself aside. The blow landed upon Tugh's jaw, but the cripple did not seem to feel it. He stuffed the struggling Larry like a bundle into the aperture. Larry felt his clutching hands torn loose. Tugh gave a last, violent shove and released him.
Larry fell into blackness—but not far, for soon he struck water. He went under, hit a flat, stone bottom, and came up to hear Tina fall with a splash beside him. In a moment he regained his feet, to find himself standing breast-high in the water with Tina clinging to him.
Tugh had disappeared. The aperture showed as a narrow rectangle some twenty feet above Larry's head.
