“Don’t move. I’ll give you another chance. I’m aiming lower this time. You’ll get it bang amidships, between wind and water, so to say, and—it’ll hurt more. You were going to stick to me till I came to your price, were you? But you’ve stuck rather too tight.”

“Oh, but—you’ll swing for this,” says the other, between dry, tremulous lips.

“Not much ‘swing.’ Why, nobody will be any the wiser. Not a soul has seen us together. You disappear, that’s all. Well, are you going to do as I tell you? I’ve got everything here—well-filled fountain pen, and paper; strangely out of place in these surroundings, still, here they are.”

The threatened man does not immediately reply. He is calculating his chances, and in a flash it is borne home to him that he has no chances. Opposite him stands a desperate and determined man dictating terms. These he will have to accept, and will feel anything but safe even then; for well he knows that the other has every motive for sending him out of the world.

“Well? Are you going to do it? I’ll count five.”

But hardly has he begun to do so than the situation changes. The man on the river brink suddenly puts his hand behind him, ducking low as he does so, to avoid the shot that simultaneously whizzes over where his chest had been a fraction of a second earlier. A revolver glints in his hand, but he is not quick enough. Before he can get in a shot the other pistol cracks again, this time with effect. He topples heavily into the water.

Yet he is struggling for his chance of life, but a glance is sufficient to show that he can hardly swim a stroke even if unwounded—which he is not. The other points his pistol for a final and decisive shot. But there is something in the wild appealing scream of the drowning wretch that unnerves him, that shatters his callous desperation. And then—the crocodiles.

“Make for this stump,” he shouts, running down the bank. “I’ll give you a hand out. Now I’m going to fire over your head.”

There is nothing now to fire at. The two motionless objects have disappeared, nevertheless he sends a bullet into the water at the place where they had been.

Splashing, kicking, panting, the drowning man makes for the stump indicated. In a moment he will have seized it and the other is running down to help him. A yard further and he will be safe. His hand is already stretched forth to grasp it, when—with a frightful scream of agony and terror he disappears beneath the surface.
