“As you say,” said Dick, in sprightly fashion, “the best thing is to forget the whole incident. Lenox, if you will give me those papers, I must be off.”

“Our lines lie parallel,” said the Swami. “Will you permit that I walk with you?”

The four who remained stood awkwardly during the departure, and with the closing of the door, Mr. Lenox gave an inarticulate ejaculation.

“Miss Elton,” he said, “I think your problem is solved.”

“You mean it was Mrs. Percival?”

“You are as sure as I.”

“And Dick knew,” said Ellery. He blushed as he spoke.

“Oh no, Mr. Norris!” cried Madeline in sharp distress. “That would he unendurable. And besides, he said he didn’t.”

“Dick lied,” Ellery stated calmly.

“I will never believe that Dick would lie.”
