"I don't calculate I'll get away before it, but I'll be in the water the minute I fire. I won't wait to see whether I hit it or not. However, I'll drop the revolver in the boat, so in case I miss the first time, it will be dry enough to use again."
"But—" began Jack.
Frank stood up in the boat and pointed the revolver directly at the submarine.
"No more words," he said quietly. "Are you ready?"
Jack lowered himself over the edge of the boat, still holding to it with his hands.
"Yes, I'm ready," he said, "but—"
"Then dive!" cried Frank and pulled the trigger.
With a single movement he dropped the revolver into the bottom of the boat, and plunged deep into the sea himself.
