Glancing over his shoulder a minute later, Austin saw the Ciga- rette boat speeding back toward land. The helicopter sheared off and rapidly outpaced the boat. He passed the yacht again. The decks were still deserted. He continued along the coast toward a headland shaped like a parrot's beak. A few minutes later, he sighted the Mer- maid's Gate at the bottom of a vertical cliff. It was amazingly sym- metrical for a natural arch. The opening was about twenty feet high and slightly narrower in width. It looked like a mouse hole com- pared to the overpowering wall of rough, brownish-black rock.

Despite its lyrical name, the Mermaid's Gate was far from wel- coming. The sea was relatively calm, but waves pounded the fang- shaped rocks on either side and in front of the arch. Spray flew high in the air. The water in front of the opening boiled and swirled with vicious cross-currents, like a giant washing machine. Over the crash of the sea, Austin heard a hollow soughing issuing from the opening. The hair rose on the back of his neck. The mournful dirge was what he imagined the moans of drowned sailors would sound like. Re- gretfully, he didn't see a single mermaid.

Austin halted the boat a respectable distance from the gate. Any attempt to pass through now would be like trying to thread a needle in a jostling crowd. Austin checked his watch and settled back and munched on the bread and cheese Pia had thoughtfully packed for him. He was finishing his breakfast when he sensed a change in the sea conditions. It was as if King Neptune had waved his trident.

While the water in the immediate vicinity was still restless, the waves no longer exploded against the archway with artillery force. Pia had said that the gate was safely navigable only on either side of a slack current.

He secured all loose objects on the boat, donned his life jacket, spread his legs wide for stability, throttled up and pointed the boat at the gate. Even at slack current, the water around the opening was dimpled by swirling vortexes. He clenched his teeth and prayed that Pia's childhood memory other father's words was accurate. When he was only yards away from the lethal reach of the rocks, he gunned the throttle, aiming slightly to the right, as instructed, although it was dangerously close to the rocks. With inches to spare, the boat slith- ered through the tight opening as easily as an eel.

Making a quick left-hand turn in the domed chamber, he headed toward a narrow cleft in the rocks and entered a canal inches wider than the double-ender. The boat banged against the kelp-covered ledges as it followed the channel in a rough S-course that widened into a circular lagoon the size of a backyard pool. The water's sur- face was black with seaweed, and the smell of the ocean was almost overpowering in the confined space.
