"Don't add another to the list of your crimes; that would be foolish."

Dixon's lips had assumed an ashen hue, and he had evidently to make a tremendous effort to stand steady.

"Oho, so it was you, Mr. Wallion," he said with some bitterness in his tone. "Well, I give in, I have got into deep water. Corman, my boy, it wasn't written in the stars that this was the way we were to get rich...." Then, looking at Wallion, he said: "And what do you intend to do with us?"

"You are my prisoner, Dixon, and you too, Corman. Go shares and then dissolve partnership, that was your program, wasn't it? Well, the six millions will be shared, but not with you, and the partnership will be dissolved, though not quite in the way you intended."

Toroni, whom Wallion had kept well under observation, stood as if glued to the spot, his piercing black eyes fixed on the "Problem Solver."

The five bargemen and the diver were huddled together in a frightened heap. Toroni looked round.

"Don't expect you'll get any help," said Wallion sternly. "Come here, Toroni.... What? ... You would? ... Look out, Tom."

Quick as lightning Toroni had taken refuge behind the gold chests, pulled out his revolver and fired; the bullet made a hole in the wall of the hut. Wallion stooped and took aim, but he could not sight his adversary. Tom caught a glimpse of Toroni's right hand as he again raised his weapon between two of the chests and fired at random without any particular aim. A flash and a bang followed; Tom felt something like the sting of a whip on his left temple. He put up his hand; his fingers were wet and smeared with blood. He let fall his Browning and believed he heard himself call out: "I am wounded"; but in reality no sound passed his lips. He took a few steps without knowing where he was going, staggered and fell forward unconscious.

Toroni had dropped on his knees. He was grinning and showing his teeth like a wild beast. Under cover of the gold chests, he shot time after time at Wallion, who promptly returned the fire, and knew he had not missed his mark, but Toroni seemed possessed of an evil spirit.

"Give in," shouted Wallion. "I want to take you alive."
