'Well, gentlemen,' said he, in a velvety voice with only the least trace of a foreign accent, 'you have come, as I understand from our short chat over the wires, in order to learn more of the Nemor Disintegrator. Is it so?'

'Exactly.'

'May I ask whether you represent the British Government?'

'Not at all. I am a correspondent of the Gazette , and this is Professor Challenger.'

'An honoured name – a European name.' His yellow fangs gleamed in obsequious amiability. 'I was about to say that the British Government has lost its chance. What else it has lost it may find out later. Possibly its Empire as well. I was prepared to sell to the first Government which gave me its price, and if it has now fallen into hands of which you may disapprove, you have only yourselves to blame.'

'Then you have sold your secret?'

'At my own price.'

'You think the purchaser will have a monopoly?'

'Undoubtedly he will.'

'But others know the secret as well as you.'

'No, sir.' He touched his great forehead.

'This is the safe in which the secret is securely locked – a better safe than any of steel, and secured by something better than a Yale key. Some may know one side of the matter: others may know another. No one in the world knows the whole matter save only I.'

'And these gentlemen to whom you have sold it.'

'No, sir; I am not so foolish as to hand over the knowledge until the price is paid. After that it is I whom they buy, and they move this safe' he again tapped his brow 'with all its contents to whatever point they desire. My part of the bargain will then be done – faithfully, ruthlessly done. After that, history will be made.' He rubbed his hands together and the fixed smile upon his face twisted itself into something like a snarl.
