Two or three days after Lomas received an invitation to lunch in Wimpole Street.

“I owe you one,” Reggie wrote. “I owe myself one. I want to forget the high tea of Alwynstow. Do you remember the pickles? And the bacon? What had that pig been doing? A neurasthenic, I fear. A student of the Nematoda.”

So naturally when Lomas came his first question was what may Nematoda be.

“Never mind,” Reggie sighed. “It’s a painful subject. A disgusting subject. Same like what we make our living by. They are among the criminals of animal life. Real bad eggs. A sad world, Lomas, old thing. Let’s forget all about crime.”

They did. For an hour and a half. At the end of which Lomas said dreamily, “You’re a remarkable fellow, Fortune. I don’t know how you can retain any brain. You do yourself so well. Yes, most seductive habit of life. I meant to say something when I came. What was it? I believe you have talked of everything else in creation. Ah, yes, did you ever hear of the Kimball case? Well, I think we have combed it all out.”

“Have you, though?” Reggie sat up.

“Yes. We’ve been dealing with a stockbroker or two. I’m really afraid there was a little bullying. We hinted that there might be developments about a certain murder case. And two of them began to talk. We’ve got Rand-Mason’s past.”

“Oh, that!” Reggie said. “Quite obvious, wasn’t it? Kimball meant to use this coal scheme to ruin Sandford. He sent Mason, who had probably been his go-between in other financial things, to give the brokers the tip. It was also Rand-Mason who paid the money into Sandford’s account. Remember the stout man in glasses. Then probably he struck for better pay or they had a row. Anyway, he threatened to give the show away. Kimball couldn’t trust him any more. Daren’t trust him. So he wiped Rand-Mason out. Is that right, sir?”

“I’m not omniscient myself. But certainly Rand-Mason was the man who put the brokers on to it. There is not much doubt he went to Sandford’s bank. By the way, Kimball had several big sticks. His valet says he liked weight.”

“I dare say. Had Kimball any papers?”
