There was something down there. He rolled up onto his feet and tramped 
straight into the ocean. Just as the waves were coming up into his face, his 
feet contacted something hard and smooth that gave way beneath him. He was 
sucked downward as the water plunged into a subterranean void. A hatch slammed 
shut above his head, and suddenly he was breathing air again. The light was 
silver. He was sitting in water up to his chest, but it rapidly drained away, 
drawn off by some kind of a pumping system, and then he found himself looking 
down a long silvery tunnel. The woman was descending it, a stone's throw ahead 
of him.
