Submarine Jim – J. S. Lome

The Shark they Hunted had a Map inside . . .

Miles the Mutineer is trying to stay out of trouble and when a gang of convicts track a shark to his door, he can’t help shying away . . . until the shark proves to be hiding a map to the largest treasure in the South Seas. Taking a bag of sea-darts and a shark-whistle, Miles joins an old pirate buddy in the hunt for treasure through a network of shipwrecks, where the key to survival may be joining their enemies. But will joining the shark-hunters mean encountering greater dangers than cut-throat convicts? Will it mean fighting the giant sea beast that guards the treasure?
