Mr. Drayton, who used to sit in a room off the front hall, of which the window commanded the garden, went as usual into the hall to see that no one went out or came in, and heard his own name mentioned by a peremptory and loud-voiced man, who demanded instant admission, to see him on urgent business.

"Tell him I have done with business, I refuse to see him."

"But you will be extremely sorry if you do not see me," said the stranger in a still louder tone. "You thought you had made a mess of those chemical work shares, but you have been a far, far cleverer man than we gave you credit for. Those shares Mr. Sandford laughed at...."

"Come in here, come in here," said Mr. Drayton, rubbing his hands with glee. "So I was right, and that old fool was wrong, hah! hah! hah!" and he laughed uproariously.

The stranger walked into the small room; he could hardly believe, he said, that Mr. Drayton's acute intelligence had been laughed at. What shares had he had in those works; what papers had he to show? Perhaps that was a matter of no moment. If the shares had been sold ... why it was a misfortune, unless he could buy them back before the discovery, the great discovery, was made known.

"What discovery?" asked Mr. Drayton, in a moment suspicious.

"That you were right and every one else wrong."

"How has that discovery been made?"

"By experiment."

"Yes; but who made the experiment?"
