For a time he listened for any sound Ignacio might m ake searching for him。 fore and knew on which side of hunger he stood。 he had several times seen coconuts lying in the sand under the trees. He moved quietly, still a little afraid, trying to think of ways to open the coconut w hen he found it. He imagined himself standing before a large and raggedly faceted stone, holding the coconut in both hands. He raised it and smashed it dow n, but when it struc k it was no longer a coconut but Maya39。 she looked up as she saw him, and smiled. Hello, he said. Hello, Nicholas. I thought I heard you. I wasn39。s probably given up by now. The girl nodded, looking into the dar k waters of they pool, but did not seem to have heard him. He began to wor k his way around to her, climbing across the sna kelike roots of the crowding trees. Why does Ignacio want to kill me, Diane? Sometimes he wants to kill me, too, the girl said. But why? I think he39。 when he was there, there wasn39。t be sick if only there weren39。 and then a turtle and a hedgehog that turned into armadillos for the love of God, Montressor.

Her eyes, as blue as the sky above Madhya Pradesh, the sparkling blue sky of the egg, looked up at him, but he could no longer look into them, they retreated from his own, and it came to him quite suddenly that Lucifer, in falling, must have fallen up, into the fires and the coldness of space, never again to see the warm blues and browns and greens of Earth: 1 was watching Sa tan fall as lightning from heaven.

Faintly water was babbling。 but his stomach revolted at the thought of the raw flesh, and he did not know how he might build a fire, although Ignacio seemed to have done so the night before.
