"On the contrary, I know exactly how you must feel, and am very glad you have spoken," rejoined Mostyn Scarth, cordially enough in all the circumstances of the case. "But the cloud is none of my making, Doctor Dollar, though I naturally feel rather strongly about the matter. But for Schickel, the chemist, I might be seeing a coffin to England at this moment! He's the man who found out the mistake, and has since made all the mischief."

"Are you sure it was a mistake, Mr. Scarth?" asked Dollar quietly.

"What else?" cried the other, in blank astonishment. "Even Schickel has never suggested that Doctor Alt was trying to commit a murder!"

"Even Schickel!" repeated Dollar, with a sharp significance. "Are you suggesting that there's no love lost between him and Alt?"

"I was not, indeed." Scarth seemed still astonished. "No. That never occurred to me for a moment."

"Yet it's a small place, and you know what small places are. Would one man be likely to spread a thing like this against another if there were no bad blood between them?"

Scarth could not say. The thing happened to be true, and it made such a justifiable sensation. He was none the less frankly interested in the suggestion. It was as though he had a tantalizing glimmer of the crime doctor's meaning. Their heads were closer together across the end of the table, their eyes joined in mutual probation.

"Can I trust you with my own idea, Mr. Scarth?"

"That's for you to decide, Doctor Dollar."

"I shall not breathe it to another soul—not even to Alt himself—till I am sure."
