"Not till you give in," replied Harry.
"Then——"
Bang! went Mason's pistol.
He did not raise it to aim, but took the young detective unawares, and the ball grazed Harry's skull, and stunned him.
Dropping his pistol, he flung up his hands, reeled back, and fell over the side of the boat upon the mud, unconscious.
At the same moment Sim, electrified, sprang convulsively at Old King Brady and knocked the pistol aside.
It was discharged in the air.
The coon seized the detective's wrists, and in a moment a terrific struggle ensued between the pair.
Old King Brady thought his partner was killed.
It made him frantic with rage.
