Sir Hugo was an easy-tempered man, tolerant both of differences and defects; but a point of view different from his own concerning the settlement of the family estates fretted him rather more than if it had concerned Church discipline or the ballot, and faults were the less venial for belonging to a person whose existence was inconvenient to him. In no case could Grandcourt have been a nephew after his own heart; but as the presumptive heir to the Mallinger estates he was the sign and embodiment of a chief grievance in the baronet's life--the want of a son to inherit the lands, in no portion of which had he himself more than a life-interest.
