The boys stood one rung above her and could peer into porthole one on either side over her head. Ann found that from where she stood she could just manage to see over the bottom edge of the round window. She could dodge down quickly if Bain happened to glance toward the porthole.

He was coming now. How different his steps sounded from the strange sussh-sussh she had heard that other day when the band visited the wreck. Bain walked lightly but he came steadily with abrupt steps that sounded like those of a human being. The other sound, she felt sure now, could not have been human. But what had made that curious noise? Ann could not bring herself to believe in ghosts.

As Bain entered the captain’s cabin he flashed his light into all the corners and the band dodged out of the glow. The port was so high from the floor that there was no danger of Bain’s seeing anything that was not directly in front of the opening.

In a minute they pulled back where they could see and all three watched the man as he examined the cabin. He gave most attention to the table. He pulled the drawer out, banging it on the floor and listening for some sound that would indicate a secret compartment; then he took out his pocketknife and ran the open blade around the joining of the wood. It was evident that he found nothing. When he began to work he fixed his torch in his belt in such a way as to allow the light to follow his hands and let him see clearly what he was doing. Once in a while he would stop and listen intently, and each time he took up his task again he worked faster than before, as if he expected interruption.

As he searched his dark face was very intent. But it did not appear evil. He looked far more friendly to Ann to-night than when she had seen him at the cove. But in spite of that she had no desire to let him know that Robin Hood’s band were spying upon him.

Under his hands one of the table legs suddenly loosened; apparently it had been screwed together in the middle where the crack was hidden by a line of decoration. The piece in Bain’s hands was hollow and from it he took a roll of paper. He opened it and grunted with satisfaction as he read. Then he slipped the paper into his pocket and replaced the table leg carefully, taking great pains to screw it tight.

He was searching for something more than the paper, for he crossed to the closet and began to shake and finger the clothes hanging there. When he found nothing in them he ran his hands up and down the closet walls, tapping them at intervals. Evidently he found what he wanted; as he latched the door he wore a pleased smile and as he turned away he said, “Stay there, sweet babies, some one will come for you.”

Such a funny thing to say! The words had no meaning for the three listeners.

Bain’s light flashed across the blankets in the berth. Ann could feel Jo start in astonishment, and glancing toward him Ann saw that his eyes, too, were riveted on the berth. She followed them and realized that the blankets were matted down as they were before Jo had shaken them that other day. Some one had been sleeping on them again; some one who had come aboard in spite of their vigilance and walked about the boat without a light. And it was not Warren Bain; that was perfectly evident, for he had taken his flashlight out of his belt and was running it slowly over the blankets.

Suddenly Bain stopped. He was listening intently. Had he heard their breathing or perhaps heard them moving against the side of the ship above his head? Ann was quite prepared to slip from her precarious perch and scamper away to the safe farmhouse.
