“And your experiment has shown you——?” David asked in a low voice.
“It confirms the theories of Tarchanoff and Jung,” he replied pedantically. “It proves the intimate connection existing between mental and physical phenomena. The personal result is still incomplete. On that side I must know more.”
“I will tell you what I can,” said David resolutely. “But first—what has Raoul written about me?”
“Merely a reference. Read it after you have told me your story. Our experiment is still unfinished, you know.”
“Unfortunately, I can’t tell you the very thing you want to know. The series of words in your test seemed to revive some forgotten nightmare; and the horror of it was that this nightmare kept just beyond my reach—as it always does—its riddle unsolved. This, with your strange knowledge of what had happened, surprised me into this ridiculous weakness.”
“So I thought,” said Leighton. “Now, what do you remember?”
“I’ll have to go back a little. But—you probably know it all, you know so much of my history.”
“Never mind. I want you to prove the truth of what I know.”
David looked at Leighton doubtfully.
“Very well,” he said, “I’ll do what I can.”
