His entrance at Harrow was signalized by the perpetration of a practical joke, which might have been attended with serious consequences. On the night of his arrival, he was instigated by young Byron, whose contemporary he was, to throw a stone at a window where an elderly lady, Mrs. Drury, was undressing. Hook instantly complied; but, though the window was broken, the lady happily escaped unhurt. Whatever degree of boyish intimacy he might at this time have contracted with his lordship, it was not sufficient to preserve him from an ill-natured and uncalled-for sneer in the "English Bards and Scotch Reviewers," an aggression amply repaid by the severe strictures which appeared in the _John Bull_ on certain of the noble bard's effusions, and on the "Satanic school of poetry" in general. The acquaintance, such as it was, was broken off by Hook's premature withdrawal from Harrow, and does not appear to have been resumed. In 1802, his excellent mother died, and with her perished the only hope of restraining the youthful Theodore within those bounds most essential to be preserved at his age, and of maintaining him in that course of study, which, if persevered in for a few years more, might have enabled him to reach a position not less honourable than that enjoyed by his more prosperous brother. Mrs. Hook appears, indeed, to have been one of those best of wives and women, who, by the unobtrusive and almost unconscious exercise of a superior judgment, effect much towards preserving the position and respectability of a family constantly imperilled by the indiscretion of its head--one who, like a sweet air wedded to indifferent words, serves to disguise and compensate for the inferiority of her helpmate.
