They all kept quite still, and the fisherman dropped a sail across the entrance, so as to prevent the firelight being seen outside.
The noise was repeated. It sounded like a groan.
"Go, Simon, see what it is," said the knight.
The man passed outside; the other two listened.
A groan, as of some one in pain, could be distinctly heard, and then a few half-uttered words.
"Who can it be, father?" whispered the girl, drawing closer to her father.
She was not a timid child, but the strange sounds in that gloomy chasm recalled the tales she had heard of the place being haunted.
"'Tis the plaint of some one in dolour," said her father.
"Simon, ask who it is."
The moaning ceased as the seaman's voice resounded in the echoing chasm.
