We watched side by side. Only one. Would he go out? The point of light, like a white star setting in a coal-black firmament, remained uneclipsed. Whoever had entered was in no haste to leave. Moreover, we had no means of telling what another obscuring of the light might mean; a departure or another arrival. There were two men about, as we knew; and it was even possible that they had entered together in one wink of the light, treading close upon each other’s heels. We both felt the sudden great desire to know for certain. But, especially, we needed to find out if perchance this was not Castro who had returned. We could not afford to lose his assistance. And should he conclude, we were out--should he risk himself outside again, in order to find us and be discovered himself, and thus lost to us when we felt him so necessary? And the doubt came. If this man was Castro, why didn’t he penetrate further, and shout our names? He ought to have been intelligent enough to guess.... And it was this doubt that, making suspense intolerable, put us in motion. We circled widely in that subterranean darkness, which, unlike the darkest night on the surface of the earth, had no suggestion of shape, no horizon, and seemed to have no more limit than the darkness of infinite space. On this floor of solid rock we moved with noiseless steps, like a pair of timid phantoms. The spot of light grew in size, developed a shape--stretching from a pearly bead to a silvery thread; and, approaching from the side, we scanned from afar the circumscribed region of twilight about the opening. There was a man in it. We contemplated for a time his rounded back, his drooping head. It was gray. The man was Castro. He sat rocking himself sorrowfully over the ashes. He was mourning for us. We were touched by this silent faithfulness of grief. He started when I put my hand on his shoulder, looked up, then, instead of giving any signs of joy, dropped his head again. “You managed to avoid them, Castro?” I said. “Señor, behold. Here I am. I, Castro.”
