But when he came over the brow of the hill and began the steep descent, he saw something in the sea below that made him give an exultant yell.

It was a motorboat, and one that he recognized immediately. The boat was none other than the Napoli, and in it were three figures. Even at that distance he knew them for Tony Prito, Phil Cohen and Jerry Gilroy. Behind the motorboat were two other craft, being towed.

He had not been seen as yet, for he saw that the Napoli was cruising leisurely around the island. He shouted hoarsely to attract attention.

He saw Tony look up, then speak excitedly to his comrades. They waved frantically in reply. Then the bow of the Napoli began to head in toward the shore.

Could they reach the boat in safety? Biff was thundering down the slope only a few feet behind Chet. Rocks and pebbles went bouncing and bounding along in front of them; sand and gravel flew from about their boots. And, coming in swift pursuit, were the two gangsters who had so nearly captured them in the thicket. These men were shouting hoarsely to them to stop.

But the two chums had no intention of stopping. They saw safety in sight. Could they reach the shore and gain the boat before the two gangsters overtook them?

Then, out from among the rocks along the beach emerged three figures. Chet's heart sank. They were the other gangsters and they were directly in the path. At the same time, he saw that Tony Prito was bringing the Napoli around, and away from the shore.

Spent and exhausted, he tried to dodge the three men ahead, but the effort was short-lived. One of the three leaped forward and grappled with him. They fell struggling into the sand. The other two leaped at Biff.

The boys fought bravely and desperately. Chet struck out and his fist crashed into the face of the man who had tackled him. The fellow sagged back for a second and Chet tried to free himself from the grasp around his waist, but as he did so one of the other two gangsters came rushing up and launched himself on him.

Biff battled with equal ferocity, but he was powerless against the three rascals. He kicked and struggled, but they had him down and they dragged him back behind the rocks, where the others soon brought Chet.
