"What!"

"Uncle Lester," said John, and his voice made a perfect match for his eye, "before I left Healthward Ho I had a little talk with Mr. Twist and his friend Mr. Molloy. They told me a lot of interesting things. Do you get my meaning, or shall I make it plainer?"

Mr. Carmody, who had bristled for a moment with the fury of a parsimonious man who sees danger threatening his cheque book, sank slowly back into his chair like a balloon coming to rest.

"Good!" said John. "Write out a cheque and make it payable to Colonel Wyvern."

"Colonel Wyvern?"

"I am passing the reward on to him. I have a particular reason for wanting to end all that silly trouble between you two, and I think this should do it. I know he is simply waiting for you to make some sort of advance. So you're going to make an advance—of a thousand pounds."

Mr. Carmody gulped.

"Wouldn't five hundred be enough?"

"A thousand."

"It's such a lot of money."
