“Alan Campbell opened one eye.

From somewhere in remote distances, muffled beyond sight or sound, his soul crawled back painfully, through subterranean corridors, up into his body again. Toward the last it moved to a cacophony of hammers and lights.

Then he was awake.

The first eye was bad enough. But, when he opened his second eye, such as rush of anguish flowed through his brain that he hastily closed them again.”
