Rick estimated that Tony and Zircon would arrive about sundown, two hours hence. The boys had flown over the Water Witch en route from St. Thomas. Apparently the scientists were enjoying the trip. Zircon had been sprawled in the cockpit while Tony trolled for fish.

"I'm a little surprised there wasn't something wrong with the plane," Rick observed. He and Scotty had gone over the Sky Wagon from propeller hub to rudder, fearful that the unknown enemy might have sabotaged the plane. But there was no sign of any tampering. However, the inspection had taken so long that it was late afternoon before they got away. It was significant and perhaps a little ominous that Steve and Jimmy Kelly had assigned a pair of husky Shore Patrol men with .45-caliber sidearms to stay with them until the plane actually took off.

"Maybe the two men who came after us were acting without orders," Scotty replied. "Maybe the real brains of the gang aren't even interested in us."

"I hope that you're right. See any coral heads?"

Although most coral growth was limited to the reef area, outcroppings of coral called "heads" had grown up toward the surface in some places. There were none in the stretch of water before the beach house where Rick planned to land.

"The water's clear. Pick your direction. There's not enough wind to make any difference."

"I'll land parallel to the beach."

Rick turned south down the center of the island. When he had reached the right position he cut the throttle, and the nose of the Sky Wagon dropped. He banked tightly, reversing course, until the plane was headed north a hundred yards out from the beach. He let the plane feel its way toward the water, then felt the first bump as the pontoons touched. In a moment they were down, and Rick swung the plane to taxi in toward their new home.

Scotty was already stripping off his shoes and socks. As the pontoons touched bottom a few yards from shore, Scotty climbed out. Rick cut the gun while his pal pulled the plane up on the beach.

Rick got out and waited until Scotty slipped his shoes on again, then they walked to the cottage.
