It was noisy. The hollow resonance of sound filled the cave like the inside of a drum but he didn't notice. He lay on the rocks and sand, his mind spiraling toward unconsciousness, and let his body make its own recovery.
Presently he regained awareness and looked about him. The cave was dim, with only a filtered greenish light to pick out black wall's and slowly swirling water. Nobody could see much below the surface—good. He studied himself. Lacerated clothes, bruised flesh and a long bleeding gash in one side. That was not good. A stain of blood on the water would give him away like a shout.
Grimacing, he pressed the edges of the wound together and willed that the bleeding stop. By the time a good enough clot was formed for him to relax his concentration the guards were scrambling down to find him. He didn't have many minutes left. Now he had to do the opposite of energizing. He had to slow metabolism down, ease his heartbeat, lower his body temperature, dull his racing brain.
He began to move his hands, swaying back and forth, muttering the autohypnotic formulas. His incantations, Tighe had called them. But they were only stylized gestures leading to conditioned reflexes deep in the medulla. Now I lay me down to sleep....
Heavy, heavy—his eyelids were drooping; the wet walls receding into a great darkness, a hand cradling his head. The noise of surf dimmed, became a rustle, the skirts of the mother he had never known, come in to bid him goodnight. Coolness stole over him like veils dropping one by one inside his head. There was winter outside and his bed was snug.
When Dalgetty heard the nearing rattle of boots—just barely through the ocean and his own drowsiness—he almost forgot what he had to do. No, yes, now he knew. Take several long, deep breaths, oxygenate the bloodstream, then fill the lungs once and slide down under the surface.
He lay there in darkness hardly conscious of the voices, dimly perceived.
"A cave here—a place for him to hide."
"Nah, I don't see nothing."
Scrunch of feet on stone. "Ouch! Stubbed my damn toe. Nah, it's a closed cave. He ain't in here."
