The Wailing Octopus: A Rick Brant Science-Adventure Story. Goodwin Harold Leland
his aqualung and explore the reef from top to bottom. And if they should really find the wreck of the Maiden Hand, there was every chance that the exploration of the wreck and the sea life it had acquired would more than compensate for the treasure none of them really hoped to find anyway. What a vacation!
He was suddenly conscious of a throb in his ears. He listened and tried to identify it. A motorboat of some kind, but it didn't sound like a very powerful one. He lifted his head and searched for it.
Scotty, too, had heard the boat. He began to tread water, lifting his mask, then rinsing it because it had fogged a little.
Rick spotted the boat. It looked like a large row-boat, powered with an outboard motor, and it was headed in their direction.
Scotty took his snorkel out of his mouth. "Better stay topside and watch. We don't want to start our vacation by getting run over."
"Too true," Rick said. "Isn't this great? I've never seen so many kinds of small fish in one place in my life. Wait until we get out to the reefs where the big ones are."
Scotty patted his spear gun. "I'll keep us supplied with fresh sea food. Wonder if there are any lobsters around?"
But Rick had stopped listening. "Scotty, that guy is heading right for us!"
The boat was getting close, and through his face plate Rick could make out the figure of a single occupant.
Scotty suddenly gripped his arm. "Rick! It's our shadow!"
Rick started. "Are you sure?"
"Yes. I don't like this. What would he come out here for? Get ready to dive." Scotty pulled his mask into place and molded it to his face, then gripped his snorkel between his teeth.
Rick followed suit and leveled off in the water in diving position, but he hesitated, waiting to see what the boat would do.
It didn't take long to find out. The boat stayed on a perfectly straight course, headed directly for them. Rick waited. Perhaps the shadow intended to sheer off when he got close. He might have come out to talk with them.
Scotty hooted four times, their signal for danger! Then he went under. Still Rick hesitated, until it was clear that the boat did not intend to swerve. He saw the shadow's face, set in grim lines, then his legs went up and he slid under, using his hands as well as his legs to pull himself down to safety. He thought incredulously, "He tried to run us down!"
A dozen feet under he turned over on his back and saw the bright circle of the propeller and its trail of foam. The boat was past. He shot to the surface and filled his lungs with air, waiting for the next move.
The boat spun around in a tight turn and headed back.
Scotty surfaced next to Rick, pulled the snorkel from his mouth, and gritted, "Swim away. Let him use you for a target. I'm going to get that son of a spiny sea walrus."
Rick saw from the position of the spear in Scotty's gun that his friend had charged the weapon during the dive. He nodded, then turned and swam away, flippers flailing as though trying to hurry. He watched over his shoulder and saw the boat head for him.
He was breathing hard from the excitement now, but he took a deep breath and got ready to dive. But still he swam, leading the rapidly overtaking boat until it was almost on him. Only then did he shoot downward, twisting as he went. He looked back in time to see Scotty sight the spear gun and fire as the boat went past.
At first Rick thought his pal had missed, then he realized what Scotty had done. The spear shaft was attached to a long wire leader, and the leader to a safety line coiled around a spool just ahead of the pistol grip. Scotty had deliberately fired ahead of the propeller, knowing that the wire leader would be caught and would wrap around the shaft.
Rick saw the spear stop short as the wire caught, saw it hauled back against the propeller and drop free as the prop blades cut it loose. Scotty shot up for a breath, then dove instantly, toward the rapidly falling spear.
Rick had to breathe himself. He surfaced, caught a quick breath, then went under again. Scotty was picking up the spear. Rick saw him place it in the gun barrel, swing the loader over the razor-sharp harpoon head, and shove down on the spring. In a moment the gun was loaded again. Luckily the spear had not bent when the prop blade hit it.
The boat had come to a halt, the engine dead. The propeller could no longer turn against the wrapping of wire and heavy fishline. Scotty hooted twice, their signal to surface, and Rick followed him up. Near the surface they separated, Rick taking the side of the boat away from his friend. He longed for a weapon, even a hand spear. But he was helpless. Scotty would have to get in the first blow with the gun. But, Rick thought, that might give him time to get over the gunwale to grapple with the shadow.
His head broke water. He pulled the snorkel from his mouth and let it hang. As luck would have it, the shadow saw him first. He stood up, oar in hands, poised for a swing at Rick's head.
Scotty's voice stopped the swing. "Don't do it or you'll get three feet of steel through you!"
The man turned and faced the needle point of Scotty's spear. The oar dropped from his hands.
Rick gulped his relief. Apparently the shadow had no weapon.
"Jump overboard!" Scotty ordered.
The man hesitated. Scotty thrust the spear gun forward. "Jump, I said!"
The shadow did, and sank in a flurry of bubbles. When he rose to the surface again, the point of the spear was against his back. "Hang on to the boat with both hands," Scotty directed.
Rick got to his side with a kick of the flippers and ran his hands over the man's clothing. He found a switch knife, which he put in his belt. "He's clean," he said. "No other weapons."
"Take a look in the boat," Scotty suggested.
Rick did so, lifting himself up on the gunwale. There was nothing in the boat but oars and a can of gasoline.
"Want to tell us why you tried to run us down?" Rick asked.
The shadow merely stared.
"Talk," Scotty ordered, "or I'll put this spear through you."
The man spoke, and his accent was the soft speech of the island. "No, you won't. I could explain running down swimmers by accident, but you could never explain putting a spear through a man in a boat. You don't want that kind of trouble."
Scotty grinned at the truth of it. "Okay," he said. "Just one thing. Don't push us too far. Stay in the water until we're ashore, and don't try to overtake us."
"Better heed that advice," Rick warned. "Come on, Scotty. Let's go." He put his snorkel in place.
Scotty moved to his side. "Welcome to the hospitable waters of St. Thomas," he said. "What say we look up some friendly sharks before we go ashore?"
CHAPTER IV
Visitors by Night
Rick and Scotty stood on the pier and watched their erstwhile shadow row slowly toward another pier some distance away.
"We probably should have tied him up and called the police," Rick remarked.
"It wouldn't have gotten us anything," Scotty disagreed. "He could always claim he didn't see us in the water. After all, it wouldn't be the first time divers had been run over by motorboats."
"It's too late now, anyway. Let's dress, then go to the hotel and tell Zircon and Tony about this."
As they dressed in the small cabin of the Water Witch, Rick spoke aloud the question that had been bothering him. "What did he have to gain by running us down? That's what puzzles me. It was a stupid thing to try, because he didn't really have much chance of getting both of us, or even one, once he failed to catch us by surprise."
"He wasn't very well prepared for murder, either," Scotty added. "No weapons except a switch knife."
Rick nodded agreement. "He was desperate," he concluded. "Suddenly he had to take a chance on getting us. He must have known it wasn't much of a chance. Either he lost his head, or he wasn't very bright. What could have made him try?"
