The man on the rail started.
“Are you going to turn back?” he shouted.
“No!” declared Frank.
“Get ready to fire,” said the scoundrel calmly.
“I guess they’ve got us,” spoke Andy, in a low voice to his brother. “We can’t risk being fired at.”
“No, I suppose not,” answered Frank bitterly. “We’ll have to run back.”
He let the head of his craft fall off in the wind.
“That’s more sensible,” commented the man on the rail. “Good-bye!” he called sarcastically as the vessels separated, the one towing the damaged motor craft forging ahead, while the Gull sailed off on the backward tack.
There were bitter feelings in the hearts of Frank and Andy Racer. They had almost solved the mystery, only to lose at the last moment. But they resolved not to give up.
