It was Jean, the one who had smuggled the diamonds over the border, and Harry was delighted over the discovery.
The young detective was a scientific boxer.
He warded off several heavy swings and gave Jean an upper cut on the mouth that split his lips open.
The man recoiled, but Harry followed him up like a bull dog.
He received a painful blow in the stomach, and caught Jean's foot as he aimed a swinging kick at the boy.
Harry clung to the man's ankle.
Giving it a jerk, he upset the Canadian's balance and Jean fell with a crash, and rolled over.
He was just going to rise when the boy pounced on him, and a fierce struggle began for the mastery.
Old King Brady would have gone to his pupil's aid had not the other wounded man drawn a pistol and opened fire on him.
A bullet whistled past the old detective's head.
