The Moros could face cold steel or hot lead without a qualm, but the fierce, stinging tacks were too much, and too unexpected. They failed to press the attack at the crucial moment and the _Swift Arrow_ slipped through the line.
As Zircon had predicted, one engine gave them enough speed to get clear, once the Moros had lost the advantage of a favorable wind. Scotty fired a few more shots at the vintas within range, then dropped to the deck.
The fight was over.
The four gathered in the pilothouse and the three boys stared at Zircon with mixed admiration and amus.e.m.e.nt.
"It"s nothing," the big physicist said modestly. "You see, in my lifetime I have been an avid reader. At one time, while at the university, I read of some round-the-world traveler using tacks in a signal gun. So I disclaim originality."
"My "Worrold Alm-in-ack" not saying about this," Chahda said, grinning.
"Is pretty lucky you have good memory for other books, Professor!"
Rick looked back at the vintas, rapidly falling astern. The pirates were well beyond gunshot now. "Victory at Sea," he proclaimed. "Thanks to the professor"s college education!"
CHAPTER XI
The Dancing Pirates
The _Swift Arrow_ rode at anchor in the gathering dusk, inside a snug bay formed by a U-shaped island of the Kinapusan Group. The island was very small, and uninhabited. It was surrounded by larger islands that formed a kind of screen.
"Let"s hope we can spend the night undisturbed," Zircon boomed as he finished the last of his coffee. "I could use a good night"s sleep."
"We all could," Rick agreed. He helped himself to more of the stew Scotty had concocted. "Funny about a fight. That one was over in a few minutes, but I feel as though I"d done a day"s work at hard labor."
"A perfectly normal reaction," Zircon replied. "Our minds and bodies are wonderful things. When we face danger our whole system goes into high gear, our endocrines pumping fluids that get our bodies ready for fast action, or for wounds. We operate at top physical efficiency. Then, when the danger is past and our minds signal that it"s time to get back to normal, we show the effects of our overstimulation by a kind of la.s.situde."
That was true, Rick knew from his own experience. It seemed that he was always scared stiff before a fight, cool as could be during it, and limp as boiled lettuce when it was over.
Zircon changed the subject. "Scotty, when you first spotted the pirates, from what direction were they coming?"
The boy thought it over. "From about due south," he said at last. "But when they spotted us the line shifted to the east, on an interception course. They came from south originally, though."
"Not from southwest?" Zircon persisted.
"No. If anything, it was a little east of south, not west."
"Uhuh. That was my impression, but I wanted to be sure. Now, according to the chart, most of the scattered islands of the Tawi Tawi Group lie more westerly than south of here. If the pirates came from due south, it means they swung wide to miss the inhabited islands."
Chahda asked, "What means this to you, sir?"
"I"m not sure. I think it means we had better search the seas to the eastward of the main Tawi Tawi chain. The pirates would certainly have come from a westerly direction if their headquarters were anywhere near Tawi Tawi."
The big scientist rose. "I don"t know about the rest of you, but I"m for bed. Who has the first watch?"
"I"m on the eight-to-midnight," Rick replied. "It"s after eight now, so I"ll stand by. Chahda relieves me at twelve, you come on at four, and Scotty finishes the night."
They had arranged the anchor watches that way because a single guard would be enough while at anchor, and it would allow each of them a good night"s sleep.
Zircon and Chahda retired at once, but Scotty lingered. The two sat on the afterdeck and watched the stars for a few moments.
"How are we doing?" Scotty asked quietly.
Rick knew what he meant. "I"m scared," he said. "It"s a big ocean, and we could miss easily. Also, I"m thinking about what Chahda said. Even if we find Shan, we won"t get Tony and Shannon back without a fight. There must be hundreds of pirates, if the fleets we"ve seen are a sample." He was sure that the northern attack had been made by a different group than the one that attacked earlier in the day.
"Do you think they"re still alive?" Scotty asked.
"We have to a.s.sume they are. What else can we do?"
"Nothing," Scotty replied sensibly. "Except say our prayers faithfully."
"Amen," Rick said. "Go on to bed. You must be tired."
"I am. See you in the morning."
After Scotty had gone below, Rick sat quietly, depending more on ears than eyes to keep watch. Again and again he reviewed every bit of information they had obtained, re-examining it to see if any nugget of value might have been overlooked. At last he decided they had done everything possible. The rest would be persistence, and luck.
His thoughts turned to home, and he wondered what his folks were doing.
It was nine o"clock, Manila time. At Spindrift it was eight this morning. The family would be gathering for breakfast, and Barby would be slipping Dismal, the family pup, sc.r.a.ps of bacon under the table.
Rick resolved to send a cable from Tawi Tawi, if they should stop there.
He knew the family would be anxious to know how things were going.
The watch ticked away without incident. A few minutes before midnight Rick woke Chahda and joined the Hindu boy in a gla.s.s of cold c.o.ke. Then he went to bed and drifted off to sleep immediately.
Some inner instinct awakened him. For a moment he lay quietly, his heart pounding, eyes blinking in the darkness. Then he heard the pad of bare feet as Scotty got to his feet.
"What"s up?" Rick whispered.
"Just restless, I guess," Scotty whispered back.
Rick was wide awake now. He slipped into shoes and trousers while Scotty did the same. A few minutes in the cool air on deck would make him sleepy again, he thought.
"On deck!" Chahda gave a wild yell. "Come quick!" The words were punctuated by gunfire.
Instantly Zircon leaped to his feet and ran for the door.
Rick emerged into the lesser darkness of the deck in time to see Chahda fire at moving shapes on the water. The Hindu boy"s shot was answered by a dozen rifles, and Rick heard Chahda gasp.
"Pirates!" Chahda yelled. "Where is light?"
For answer, Scotty switched on the boat"s searchlight and swiveled it.
Rick shouted. A dozen vintas were closing rapidly, propelled by paddles.
Fleetingly he thought that some sound or sense of danger must have awakened him, then he grabbed for Shannon"s bow, realized in the same instant that it would do little good in the darkness, and put it back.
Zircon took the pistol from Chahda while Scotty found his rifle. The two started a steady fire that was returned in ragged volleys as the pirates tried to shoot out the light. They came close, but the light stood undamaged. Rick thanked his guardian angel that they were poor shots.
