The house of the harbor-master was a little ivy-covered cottage that stood on the east end of the quay, near the bridge that crossed the river. The harbor-master himself was an unmarried elderly man, who enjoyed the curious distinction of having always worn short petticoats. His full and correct name seems almost to have been lost. He was known as Tommy-Bill-beg, a by-name which had at least a certain genealogical value in showing that the harbor-master was Tommy the son of Little Bill. When Danny reached the cottage he knocked, and had no answer. Then he lifted the latch and walked in. The house was empty, though a light was burning. It had two rooms and no more. One was a dark closet of a sleeping-crib. The other, the living room, was choked with nearly every conceivable article of furniture and species of domestic ornament. Shells, fish-bones, bits of iron and lead ore, sticks and pipes lay on tables, chairs, chests, settles, and corner cupboards. A three-legged stool stood before the fire-place; and with all his wealth of rickety furniture, this was probably the sole article which the harbor-master used.

There was a facetious-faced timepiece on the mantel-piece; and when folks pitied the isolation of Tommy-Bill-beg, and asked him if he never felt lonely, he always replied, "Not while I hear the clock tick." But Tommy-Bill-beg had not heard the clock tick for twenty years. He resembled Jemmy Quark in being almost stone-deaf, and had a further bond of union with the gardener of Balladhoo in being musical. He played no instrument, however, except his voice, which he believed to be of the finest quality and compass. The harbor-master was wofully wrong as to the former, but right as to the latter; he had a voice like a rasp, and as loud as a fog-horn. Printed copies of ballads were pinned up on various parts of the wall of his kitchen. Tommy-Bill-beg could not read a line; but he would rather have died than allow that this was so, and he never sang except from print.

Danny Fayle knew well how often the musical weakness of the harbor-master was played upon by the Peel men; and when he found the cottage empty he suspected that some wags of fisher-fellows had decoyed Tommy-Bill-beg away to the "Jolly Herrings" for the sport of having him sing on this their last night ashore. Danny set off for the inn, which was in Castle Street. He walked along the quay, intending to turn up a passage.

The night seemed darker than ever now, and not a breath of wind was stirring. The harbor on Danny's left was some twenty yards across, and another twenty yards divided the mainland from the island rock, on which stood the ruins of the old fortress. The tide was out, and the fishing-luggers lay at secure anchorage on the shingle, and in six inches of mud. The pier was straight ahead, and there the light should now be burning.

As Danny approached the passage that led up to Castle Street he heard the distant rumble of noisy singing. Yes, it came from the "Jolly Herrings" beyond question, and Tommy-Bill-beg was there airing his single vanity.

Danny was about to turn up the passage when, in a lull in the singing, he thought he caught the sound of voices and of the tread of feet. Both came from the rock outside, and Danny could not resist the temptation to walk on and listen.

There could be no doubt of it. Some people were going up to the castle. What could they want in that desolate place at night, and thus late? In Danny's mind the ancient castle had always been encircled by ghostly imaginings. Perhaps it was fear that drew him to it now. Probably ordinary common-sense would have suggested that Danny should run off first to the harbor-master with the message that he had been charged to deliver, but Danny had neither part nor lot in that ordinary inheritance.

Near the bottom of the ebb tide the neck that divided the pier from the castle could be forded. Danny stole down the pier steps and crossed the ford as noiselessly as he could. A flight of other steps hewn out of the rock went up from the water's edge to the deep portcullis. Danny crept up. He found that the old notched and barred door leading into the castle stood open. Danny stood and listened. The footsteps that he heard before were now far ahead of him. It was darkest of all under these thick walls. Danny had to pass the doorway of the ruined guardroom, terrible with the tradition of the black dog. As he went by the door he turned his head toward it in the darkness. At that instant he thought he heard something stir. He gasped, but could not scream. He stretched his arms fearfully toward the sound. There was nothing. All was still once more; only the receding footsteps dying away. Danny thought he had deceived himself. It was as though he had heard the rustle of a dress, but it must have been the soft rustle of leaves.

Yet there were no trees in the castle.

Danny stepped forward into the courtyard. His feet fell softly on the grass that now grew there. But he stopped again, and his heart seemed to stand still. He could have sworn that behind him he heard a light stealthy tread. Danny dropped to his knees, breathless and trembling.
