They raised the sails and went over the sea toward Erin, till they saw a large ship on one side of them.
"If it's going to help us that ship is," said Fin, "'tis all the better for us, but if 'tis going against us she is, that's the bad part of it."
As the ship came near, Gilla na Grakin looked at her sharply, and said to Fin, "I think it's Lun Dubh that's on that ship."
"Well," said Fin, "maybe he'll not know you in a strange dress."
When Lun Dubh came alongside, he called out: "I know you well, and it's not by your dress that I know you, Césa MacRi na Tulach." Then Lun Dubh sprang on deck, raised his hand, struck Gilla, and stretched him dead.
Fin sailed away with the body of Gilla na Grakin, and when he came in sight of the shore of Erin he raised a black flag; for he had promised Gilla's wife to raise a white flag if her husband was well, but a black one if he was dead.
When he came to the shore, Scéhide ni Wánanan was there before him, and she had a large, roomy box. When she saw Fin she said, "You have him dead with you?"
"I have," said Fin.
"What will you do with him now?" asked she.
"I will bury him decently," said Fin.
