It was about one o’clock when a boat came into the bay from the sea, and after reaching quiet waters, edged around into the channel. Naturally Leslie did not know that it was their own Swallow, borrowed from Beth and Dalton by Mr. Tudor, though he had not come for it till long after the first party had left the Eyrie. Sarita had gone to sleep, lulled by the gentle rocking of their boat, for the wait seemed long. Her head was on Leslie’s shoulder, but she was startled awake when Peggy clutched Leslie and whispered, “Oh, who is this? One of Bill’s spies?”

“Sh-sh,” Jack warned. But it would not be easy to see them among the shadows of the rocks, and presently they saw the boat no longer as it gently glided farther within the channel, and none too soon for its occupant, for two more boats, rapidly rowed, approached the mouth of the Cove. In one was Tom, who was given final orders and directions by the man in the other boat.

Bay and Cove were comparatively calm. The night, too, was clear so far, bright with stars and a late moon, a condition good for the watchers, but not so favorable to any underhand project. The girls located the dark opening into the cave and watched tensely.

The one boat waited at the rocks which marked the beginning of the Cove. Tom’s boat entered the Cove and went straight across to the mouth of the cave, with only one exception, when Tom avoided a foaming, restless stretch where some hidden rocks lurked like Scylla of old.

“Look! He’s gone right on in,” said Leslie, “without a bit of trouble!”

“Wait till you see if he ever comes out again,” Sarita returned, for she still more than half believed in the old story.

“If he does and they get away all right, let’s go in, too,” Peggy suggested, a wild desire to see the inside of that cave taking possession of her. They could take the same course. That boat had kept steady, unharmed, not tossed about by any current or whirlpool.

“It would be safe enough,” said Jack, looking at his watch, “if we can do it before the tide comes up much. It is not quite low tide now. I looked up the tides before we came out. It will be easier to get in at low tide, though we may have to watch for rocks more. Make up your minds what you want to do, girls.”

“If it were a question of wanting,” said Leslie, “I’d say go at once, but I’m not sure it would be very safe. What do you think, Sarita?”

But Sarita did not answer, for at that moment Tom’s boat shot out from the dark, spray-washed entrance. All had seen the flash of light, presumably from Tom’s flashlight, as he took his bearings before starting out of the cave. Two figures were in the boat this time. Over the legend-cursed waters of Pirates’ Cove Tom’s boat sped, faster than when it was attempting an unknown course. Again they saw him avoid the one tempestuous spot. Again they saw him reach the rocks and the buoy where the other boat waited.
