'Sit down, young fellow,' he invited. 'Are you an American?'

'I am,' Lavendale admitted. 'My name is Ambrose Lavendale and I was attached to the Embassy here until last August.'

'That so?' the other replied with some interest. 'Well, mine's Hurn. I don't know a soul in London and you may be useful to me, so if you like I'll answer your question. You thought my laugh abominable, I guess?'

'I did,' Lavendale assented,—'we all did. I dare say you heard some of the comments that followed you out!'

'It was a selfish laugh, perhaps,' the little man continued thoughtfully, 'but it was not an inhuman one. Now, sir, I will answer your question. I will tell you what that piece of information which I heard at the bar, and which I find in the paper here, means to me and means to the world. Hold tight, young man. I am going to make a statement which, if you are sensible enough to believe it, will take your breath away. If you don't, you'll think I'm a lunatic. Are you ready?'

'Go ahead,' Lavendale invited. 'I guess my nerves are in pretty good order.'

Mr. Hurn laid the flat of his hand upon the table and looked upwards at his companion. He spoke very slowly and very distinctly.

'I can stop the war,' he declared.

Lavendale smiled at him incredulously—the man was mad!

'Really?' he exclaimed. 'Well, you'll be the greatest benefactor the world has ever known, if you can.'
