"You are wrong," Cartwright reminded him. "There are four."

Both of them looked at West.

"Of course," decided Nevin. "There are four of us."

Cartwright spread the napkin in his lap. "Perhaps, Louis, we might as well let Mr. West see the painting."

Nevin hesitated. "I'm not quite satisfied, Cartwright...."

Cartwright clucked his tongue. "You're too suspicious, Louis. He had the creature, didn't he? He knew about your painting. There was only one way that he could have learned."

Nevin considered. "I suppose you're right," he said.

"And if Mr. West should, by any chance, turn out to be an impostor," said Cartwright, cheerfully, "we can always take the proper steps."

Nevin said to West: "I hope you understand."

"Perfectly," said West.
