No sister could view him now without concern. There was an expression she had heard her husband James Schoonmaker use to describe an acquaintance of whose mentality his opinion was low, which seemed to her to fit the ninth Earl of Emsworth like the paper on the wall. It was the expression, "He has not got all his marbles." What had occurred in the past few days, and particularly what had occurred tonight, had left her with the conviction that, whatever the ninth Earl's merits, he offered an open target for her James's criticism. He was amiable, he was clean, sober and obedient, but the marbles in his possession were virtually non-existent.
