Jack flung himself into the river as Davis showed his face on deck.
CHAPTER XXI.
AT SEA AGAIN.
Edwards, also about to leap overboard at that moment, paused, raised his revolver, took careful aim at Davis and fired. Davis uttered a hoarse cry, dropped his own weapon, and crumpled up on the deck. Edwards smiled grimly, dropped his revolver and leaped lightly into the water.
He came up a moment later beside Jack, who was treading water while he awaited him.
"Which way, sir?" asked Edwards. "You know where we are. I don't."
"This," said Jack, "is the Thames. We'll have no trouble making shore. Follow me."
Edwards did so and a few moments later both stood dripping on land.
