The Fisherman's Son and the Gruagach of Tricks
He forgot his son's warning.
That minute the Gruagach na g-cleasan called out: "I'll take the worth of my money out of your son now;" and away he went with the hound.
The old man walked home alone that night, and it is a heavy heart he had in him when he came to the old woman without the son. And the two were lamenting their lot till morning.
Still and all, they were better off than the first time they lost their son, as they had plenty of everything, and could live at their ease.
The Gruagach went away home, and put the fisherman's son in a cave of concealment that he had, bound him hand and foot, and tied hard knots on his neck up to the chin. From above there fell on him drops of poison, and every drop that fell went from the skin to the flesh, from the flesh to the bone, from the bone to the marrow, and he sat there under the poison drops, without meat, drink, or rest.
In the Gruagach's house was a servant-maid, and the fisherman's son had been kind to her the time he was in the place before.
On a day when the Gruagach and his eleven sons were out hunting, the maid was going with a tub of dirty water to throw it into the river that ran by the side of the house. She went through the cave of concealment where the fisherman's son was bound, and he asked of her the wetting of his mouth from the tub.
"Oh! the Gruagach would take the life of me," said she, "when he comes home, if I gave you as much as one drop."
"Well," said he, "when I was in this house before, and when I had power in my hands, it's good and kind I was to you; and when I get out of this confinement I'll do you a turn, if you give me the wetting of my mouth now."
The maid put the tub near his lips.
"Oh! I can't stoop to drink unless you untie one knot from my throat," said he.
Then she put the tub down, stooped to him, and loosed one knot from his throat. When she loosed the one knot he made an eel of himself, and dropped into the tub. There he began shaking the water, till he put some of it on the ground, and when he had the place about him wet, he sprang from the tub, and slipped along out under the door.
