'So you would threaten me,' Laputa said very gently. Then in a burst of wrath he shouted, 'They will follow me to hell for my own sake. Imbecile, do you think my power is built on a trinket? When you are in your grave, I will be ruling a hundred millions from the proudest throne on earth.'

He sprang to his feet, and pulled back a shutter of the window, letting a flood of light into the hut. In that light I saw that he had in his hands the ivory box which had contained the collar.

'I will carry the casket through the wars,' he cried, 'and if I choose never to open it, who will gainsay me? You besotted fool, to think that any theft of yours could hinder my destiny!' He was the blustering savage again, and I preferred him in the part. All that he said might be true, but I thought I could detect in his voice a keen regret, and in his air a touch of disquiet. The man was a fanatic, and like all fanatics had his superstitions.

'Yes,' I said, 'but when you mount the throne you speak of, it would be a pity not to have the rubies on your neck after all your talk in the cave.'

I thought he would have throttled me. He glowered down at me with murder in his eyes. Then he dashed the casket on the floor with such violence that it broke into fragments.

'Give me back the Ndhlondhlo,' he cried, like a petted child. 'Give me back the collar of John.'

This was the moment I had been waiting for.

'Now see here, Mr Laputa,' I said. 'I am going to talk business. Before you started this rising, you were a civilized man with a good education. Well, just remember that education for a minute, and look at the matter in a sensible light. I'm not like the Portugoose. I don't want to steal your rubies. I swear to God that what I have told you is true. Henriques killed the priest, and would have bagged the jewels if I had not laid him out. I ran away because I was going to be killed to-day, and I took the collar to keep it out of Henriques' hands. I tell you I would never have shot the old man myself. Very well, what happened? Your men overtook me, and I had no choice but to surrender. Before they reached me, I hid the collar in a place I know of. Now, I am going to make you a fair and square business proposition. You may be able to get on without the Snake, but I can see you want it back. I am in a tight place and want nothing so much as my life. I offer to trade with you. Give me my life, and I will take you to the place and put the jewels in your hand. Otherwise you may kill me, but you will never see the collar of John again.'

I still think that was a pretty bold speech for a man to make in a predicament like mine. But it had its effect. Laputa ceased to be the barbarian king, and talked like a civilized man.

'That is, as you call it, a business proposition. But supposing I refuse it? Supposing I take measures here—in this kraal—to make you speak, and then send for the jewels.'
