Kenneth Gregory listened quietly, at times interrupting with rapid-fire questions.

"When was he last seen?"

"Three days ago."

"You knew nothing of his plans?"

"Nothing definite," Blair evaded. "He might have gone out with the fishermen scouting for albacore. One of Lang's boats turned up missing the next morning. Lang himself is missing, too."

"Who is Lang?"

"Your father's fishing captain. He recently bought him a number of new boats. They might have gone to try one of them out."

"Nothing has been heard of them since?"

"Not yet. You see it has been very foggy lately all along the coast. That has handicapped our search."
