“Smith,” he said, “I should like to see you alone for a moment. Mr. Downing might I trouble—? Adair, Jackson.”

He made a motion towards the door.

When he and Psmith were alone, there was silence. Psmith leaned back comfortably in his chair. The headmaster tapped nervously with his foot on the floor.

“Er—Smith.”

“Sir?”

The headmaster seemed to have some difficulty in proceeding. He paused again. Then he went on.

“Er—Smith, I do not for a moment wish to pain you, but have you—er, do you remember ever having had, as a child, let us say, any—er—severe illness? Any—er—mental illness?”

“No, sir.”

“There is no—forgive me if I am touching on a sad subject—there is no—none of your near relatives have ever suffered in the way I—er—have described?”

“There isn’t a lunatic on the list, sir,” said Psmith cheerfully.
