Surrounded

switched off and the pool's surface permitted to resolve itself, they would be caught.
        However, while that was his greatest worry, it was not Tucker's only concern. He worried that their air supply- three hours which might be stretched to three hours and ten minutes by their relative inactivity-might not be sufficient to last them through the search of the mall. They might be forced to go up before the police had left; and their cleverness and planning would not count for anything.
        He was also worried that some lucky cop, in searching Surf and Subsurface, would accidentally discover the empty containers that had once held the scuba suits and aqualungs that he, Meyers, and Bates were now using. Meyers had said that after removing the gear, he had placed the boxes back on the shelves where he had found them, leaving no traces. He had done the same with the boxes that had contained the bright-yellow waterproof sacks in which they now stored the money, jewels, and clothing; and he had made certain that the pressurizing equipment that had charged the scuba tanks was turned off and left just as he had come across it. Nevertheless…
        Tucker worried. He wondered if he should have removed the sign board that had stood beside the fountain and had carried a notice of the following week's novelty diving act. If Kluger saw the sign and took the time to read it, would he then realize that the pool, being deep enough to accommodate a diving act, was deep enough to conceal three desperate men?
        When the three of them had slipped into the pool with the two plastic-encased bank bags and the waterproof sacks full of clothing, had they appreciably raised the water level? Would that be noticed by anyone up there who was familiar with the mall? Had they raised the water level so far that tens of gallons had poured over the rim and onto the lounge floor?
        Were the rising bubbles from their aqualungs really concealed in the surface turmoil caused by the fountain? Or were they quite evident, awaiting a keen eye and quick mind to be properly interpreted?
        He worried.
        Every ten minutes he raised his wrist to his face, put the dial of his watch against the view plate of his snugly fitted diving mask, and checked the time. With as much humor as he was capable of at the moment, he thought that this would all make an excellent television commercial for the watch company, a convincing demonstration of the durability of their fine product. The slender, luminous hands crawled slowly but inexorably around the glowing green numerals, while the equally phosphorescent sweep second hand just whirled and whirled and whirled…
        

    2:30.
        
        The rubber mouthpiece that fitted past his teeth and fed air to him had a foul taste. His tongue seemed to be coated with a bitter fluid, and his saliva grew thick and rank. It was gradually making him sick to his stomach. The tanked air itself was stale, flat, unpleasant, and yet too oxygen-rich. He worked his lips around the device in his mouth, trying to make it fit more comfortably than it did, and he saw that both Frank Meyers and Edgar Bates were similarly occupied.
        

    3:00.
        
        He had the curious sensation of being both hot and cold at the same time. Inside the tight rubber scuba suit he was slick with nervous perspiration, yet was simultaneously aware of the unrelenting cold that seeped through to him from the water.
        

    3:30.
        
        He leaned back against the wall of the pool and tried to think about Elise and about all they had done and would do together. Staring at the shimmering green-blue water in front of him, he attempted to picture the Edo shield and spear, several other more minor treasures that he possessed… But he could not make himself feel better. His eyes continually drifted to the trails of fat bubbles rising from Meyers and Bates, then followed the bubbles to the shimmering, foaming surface…
        

    3:40.
        

    3:50.
        

    4:00.
        
        He worried.
        There was really nothing else to do.
        And his anxiety seemed justified when, at 4:40, the fountain was shut off. The surface of the pool stopped shimmering. The milkiness gave way to light. The film of spume fizzed and dissolved. In two minutes the surface was fully transparent. Tucker could look up and see the peaked ceiling, the fake rocks at the edge of the water… He figured it
