'That escutcheon is the best thing of the kind I have yet made,' he said. 'A humour I have, never to be contented to produce any invention the second time, without appearing refined. The lock and key of this are in themselves a marvel, for the little triangle screwed key weighs no more than a shilling, and yet it bolts and unbolts an hundred bolts through fifty staples round about the chest, and as many more from both sides and ends, and at the self-same time shall fasten it to a place beyond a man's natural strength to take it away. But the best thing is the escutcheon; for the owner of it, though a woman, may with her own delicate hand vary the ways of coming to open the lock ten millions of times, beyond the knowledge of the smith that made it, or of me who invented it. If a stranger open it, it setteth an alarm agoing, which the stranger cannot stop from running out; and besides, though none should be within hearing, yet it catcheth his hand, as a trap doth a fox; and though far from maiming him, yet it leaveth such a mark behind it, as will discover him if suspected; the escutcheon or lock plainly showing what moneys he hath taken out of the box to a farthing, and how many times opened since the owner hath been at it.' He then showed her how to set it, left the chest open, and gave her the key off his bunch that she might use it more easily. Ere she returned it, she had made herself mistress of the escutcheon as far as the mere working of it was concerned, as she proved to the satisfaction of the inventor. Her docility and quickness greatly pleased him. He opened a cabinet, and after a search in its drawers, took from it a little thing, in form and colour like a plum, which he gave her, telling her to eat it. She saw from his smile that there was something at the back of the playful request, and for a moment hesitated, but reading in his countenance that he wished her at least to make the attempt, she put it in her mouth. She was gagged. She could neither open nor shut her mouth a hair's breadth, could neither laugh, cry out, nor make any noise beyond an ugly one she would not make twice. The tears came into her eyes, for her position was ludicrous, and she imagined that his lordship was making game of her. A girl less serious or more merry would have been moved only to laughter. But lord Herbert hastened to relieve her. On the application of a tiny key, fixed with a joint in a finger-ring, the little steel bolts it had thrown out in every direction returned within the plum, and he drew it from her mouth. 'You little fool!' he said, with indescribable sweetness, for he saw the tears in her eyes; 'did you think I would hurt you?' 'No, my lord; but I did fear you were going to make game of me. I could not have borne Caspar to see me so.'
