The racing motor receded, leaving him in silent darkness. He rolled over into normal swimming position and consulted his wrist compass. The creek entrance ran on a course of 80 degrees. If Scotty had gauged things correctly, that course would take him into the cove. If Scotty hadn't, Rick Brant would end up on the beach like a stranded whale.
Rick considered. The boat was gone, and it was extremely unlikely anyone had seen him leave it. The turn had caused the boat to tilt, lifting the side away from him. He was certain that the guards had not seen the maneuver. That being so, and taking into account his distance from the creek entrance, he thought it would be safe to look and check his course.
He held the compass in front of his eyes, and rose to the surface. He broke through slowly and without a splash. One look was enough. He should have trusted Scotty. He was dead on course.
Rick went to the bottom and began the long swim, counting his leg strokes. He and Scotty had practiced estimating underwater distance by the number and timing of their leg strokes. It wasn't an exact method, of course, but it was practical.
There were no underwater obstacles, and the depth was great enough. Rick remembered from the chart that the entrance into the creek varied from eight to eleven feet, dropping inside the creek mouth to about seven. No bullet could harm him if he stayed on the bottom. If the night watchers fired, the bullet would be slowed by the water.
He heard the sound of a motor and recognized it as the runabout. The sound faded again. Scotty was going through some kind of maneuvers. Then, in a short time, another motor made itself felt, more than heard. The slower beat identified it as Orvil Harris's crab boat. He was nearing the cove!
Like all divers, Rick's ears were sensitive to pressure changes. Sensing when the depth lessened, he knew he had reached the cove itself. Now to find the payload—if it was a payload. His groping hands began the search.
The first foreign object he touched was a cord. It was the wrong thickness for his own line, and he felt along it until he came to a soft, round mass, and knew he was touching one of Orvil's crab baits. He grinned in spite of the mouthpiece. Wouldn't Orvil be surprised if a diver came up hanging to his bait!
He let the crab line drop and continued his search. Once, Orvil passed within a few feet of him, and Rick wondered if the crabber had noticed the air bubbles from his regulator.
Rising ground told Rick he had reached the end of the cove. He turned left and held his course for about twenty feet, then turned left again, heading back toward the cove entrance. His hands never stopped moving, probing the mud for a trace of fish line. He crossed another of Orvil's crab lines, and kept going until pressure change told him he was back in the deeper water at the creek entrance. He turned right again. A check of his compass told him he was on course.
