"Make believe!" cried Cuckoo, childishly.
"Exactly."
"What about?"
"I want you to 'make believe' that Mr. Cresswell is not himself—is not sane."
"O-oh-h!" said Cuckoo, with a long intonation of surprise.
"I do honestly believe it; you are to pretend to believe it. Now, remember that."
"All right."
"You are not to contradict any more, you see."
"Oh," began Cuckoo, in sudden distress. "Pardon. I didn't—"
"Hush! That's all right. Act with me on the make-believe or assumption that Mr. Cresswell is not himself at present."
