She liked to fly out over the Pacific all by herself. I don't know why; she just liked to flirt with danger, maybe. One time she came in a couple of hours over-due. Figuring she was down in the drink, I was about to rouse out the Navy to hunt for her when she came in." He paused.

Mercedes was silent. In the front of the raft, Retch said nothing. His eyes were still searching the skyline.

"She was wildly excited," Parker went on. "She said she had made a forced landing on an island somewhere off the coast of Southern Cal. She also said there were a lot of strange people living on the island." He shook his head. There was a feeling in him he did not like.

His eyes came to focus on a ripple in the water. A shark. It made him think of Dr. Yammer.

"What 'appened then?" Mercedes asked softly.

"I helped her look for the island," Parker said. "We spent months looking in our spare time. We flew over more ocean than I ever knew existed. But we didn't find it."

"No?"

"That island was awfully important to her. She thought something wonderful was there, what it was, she could not tell me, just that it was there. When we could not find it, she began to doubt herself, to think perhaps she had not seen it, that she had not landed there. She reached the conclusion then--well, she went to see one of these fancy mental specialists who know everything about nothing and nothing about anything."

Under the water, he could see the eyes of the shark. They reminded him of the expression in Dr. Yammer's eyes, except that the shark's eyes looked more honest.

"And then?" Mercedes said, very softly.

"She--vanished," Parker said. "Yammer was going to stick her into a hospital, use something that he called 'shock' on her, maybe operate.

She ran away."

"Did you try to find her, Beel?"

"For asking that question, Mercedes, I ought to choke you!" Parker said hotly. "I hunted high and low. All we knew for certain was that her plane was missing. I think she decided she would simply fly out to the sea she loved, and never come back." Again his voice sank to a whisper as he visualized Effra of the Green Eyes flying out over this wilderness of waters.

"I am sorry, Beel," Mercedes said gently. "Will you remember one thing, Beel?"

"Sure. What is it?"

"You saved my life back there. I will not forget it. If the time ever comes, I will pay my debt."

"Thank you," Parker said. "But there is no debt."

"You think this island we are hunting might be the same island your girl claimed she found?" Retch spoke from the front end of the boat.

"And if it is the same island?" Mercedes said.

Anger came boiling up in Parker. "If it is that island, and if I ever get back to Los Angeles, I am going to hunt up a psychiatrist by the name of Yammer and take care of him!" Parker dug the water savagely.

Gradually, his anger subsided. "Where did you run into the rumor about this island?"

Retch shrugged. "It was just one of those things you hear." He studied the landscape. "We should spot a boat soon."

"We are not exactly on the well-traveled ocean lanes," Parker pointed out. "Does it happen that there are any other little things about this island that you forgot to tell me when you chartered my ship to fly you down here?"

Retch flushed. "Such as--"

"Such as how it happened that my 'copter threw a vane just after we sighted the place?"

Retch did not answer.

"Seemed as though somebody shot at us."

"Oh h.e.l.l no! The loss of the vane was accidental."

"Accidents like that can happen but they usually don't. I checked the ship before we took off." Parker turned silent. There was no proof that the wrecking of the 'copter had been anything but an accident. "What do you expect to find on this island?"

"I told you--"

"Just before the 'copter started down, Miss Valdar was yakking about how we were all going to be rich," Parker interrupted.

The glance Retch gave Mercedes had no love in it. "Sometimes she's got her mouth open when she ought to have it shut."

Mercedes was silent. "I see," Parker said. "When you chartered my ship, you told me you were a scientist and that you wanted to investigate certain phenomena on this island. You said your investigation would take only a few hours. I was to fly you here and wait for you. You said you might want me to fly you back to the mainland, or might not, depending on what you found here. Is this correct?"

"Certainly," Retch answered. "I'm sorry you lost your ship but the insurance will take care of it."

"Insurance will take care of the 'copter but not of my neck. _Are_ you a scientist?"

"Of course. Didn't I tell you--"

"What kind of a scientist are you?"

"I--ah--What do you mean?"

"What's your specialty? Are you a biologist, a physicist, or what?"

"I--"

"I don't believe you are a scientist at all. You don't talk like one."

"d.a.m.n it, I told you what I am and that's what I am!" Retch's face showed sullen and his hand moved toward the gun. Parker tensed. Retch stopped the movement of his hand. He glared at the big pilot.

"Okay," Parker said. "It doesn't make any difference anyhow." He resumed paddling.

The sun slid down the western sky. Retch and Mercedes huddled in the front end of the raft and whispered to each other. From time to time, the woman glanced at Parker. He paid no attention to her.

The sea was calm. In the distance, a school of flying fish skittered over the surface. A dozen gulls played near the surface. A high-riding fin cut the water. Shark, sensing food.

The sun reached the horizon and wallowed in the sea like a fat, round shining pig on fire.

Mercedes screamed, pointed, jerked a terror-stricken face toward Parker.

"Beel! Beel!" She scuttled across the raft, threw herself into his arms.

"Look, Beel, look!"

Terror and panic almost beyond understanding were in her words.
