Then he saw it again. It was a little closer. A round dark patch on the water, like a big mole, rising and falling on the mild waves. When he had first seen it the patch had been maybe forty yards from the raft. Now it was only half that distance.
"Pancho, you ees some kine of beeg asshole," Deke said happily. He pulled Randy up.
"Cold enough for you? You sober yet?"
"I'm sober! I'm-sober!" He began to jump around as Deke had done, clapping his arms across his chest and stomach in an X. They turned to look at the girls.
Rachel had pulled ahead of LaVerne, who was doing something that looked like a dog paddle performed by a dog with bad instincts.
"You ladies okay?" Deke bellowed.
"Go to hell, Macho City!" LaVerne called, and Deke broke up again.
Randy glanced to the side and saw that odd dark circular patch was even closer—ten yards now, and still coming. It floated on the water, round and regular, like the top of a large steel drum, but the limber way it rode the swells made it clear that it was not the surface of a solid object. Fear, directionless but powerful, suddenly seized him.
"
"Ow!
"LaVerne!
LaVerne looked up, maybe not hearing the terror but at least hearing the urgency. She looked puzzled but she dog-paddled faster, closing the distance to the ladder. "Randy, what's wrong with you?" Deke asked. Randy looked to the side again and saw the thing fold itself around the raft's square corner. For a moment it looked like a Pac-Man image with its mouth open to eat electronic cookies. Then it slipped all the way around the corner and began to slide along the raft, one of its edges now straight.
"Help me get her up!" Randy grunted to Deke, and reached for her hand. "Quick!" Deke shrugged good-naturedly and reached for LaVerne's other hand. They pulled her up and onto the raft's board surface bare seconds before the black thing slid by the ladder, its sides dimpling as it slipped past the ladder's uprights.
"Randy, have you gone crazy?" LaVerne was out of breath, a little frightened. Her nipples were clearly visible through the bra. They stood out in cold hard points.
"That thing," Randy said, pointing. "Deke? What is it?" Deke spotted it. It had reached the left-hand corner of the raft. It drifted off a little to one side, reassuming its round shape. It simply floated there. The four of them looked at it.
"Oil slick, I guess," Deke said.
"You really racked my knee," Rachel said, glancing at the dark thing on the water and then back at Randy. "You—"
"It's not an oil slick," Randy said. "Did you ever see a round oil slick? That thing looks like a checker."
"I never saw an oil slick at all," Deke replied. He was talking to Randy but he was looking at LaVerne. LaVerne's panties were almost as transparent as her bra, the delta of her sex sculpted neatly in silk, each buttock a taut crescent. "I don't even believe in them. I'm from Missouri."
"I'm going to bruise," Rachel said, but the anger had gone out of her voice. She had seen Deke looking at LaVerne.
"I saw one on the Cape, four years ago," he said. "We all pulled birds out of the surf and tried to clean them off—"
"Ecological, Pancho," Deke said approvingly. "Mucho ecological, I theenk." Randy said, "It was just this big, sticky mess all over the water. In streaks and big smears.
It didn't look like that. It wasn't, you know,
