Could I speak to you for a moment, madam?' said Nannie to Agnes. It was at moments of crisis like this that Mary chiefly envied her Aunt Agnes's imperturbable disposition. Most mothers feel a hideous sinking at the heart when these fatal words are pronounced, but Agnes only showed a kindly and inactive interest. In anyone else Mary might have suspected unusual powers of bluff, hiding trembling knees, a feeling of helpless nausea, flashes of light behind the eyes, storm in the brain, and a general desire to say 'Take double your present wages, but don't tell me what it is you want to speak to me about.' But Agnes, placidly confident in the perfection of her own family and the unassailable security of her own existence, was only capable of feeling a mild curiosity and barely capable of showing it.
