He turned the nose of the boat southward, a hazardous proceeding, for he ran into clear water, and had only just got back into the shelter of the providential fog bank when the white beam came stealthily along the edge of the mist. Presently it died out, and they saw it no more.

"They're looking for us," said Marcus again.

"You said that before," said the girl calmly.
