Thursdale stood perplexed. He had seen, on the previous day, no trace of jealousy or resentment in his betrothed: he could still hear the candid ring of the girl's praise of Mrs. Vervain. If she were such an abyss of insincerity as to dissemble distrust under such frankness, she must at least be more subtle than to bring her doubts to her rival for solution.

It therefore affords a fair field for a discussion of the general principles of liability for unintentional wrongs at common law. For it can hardly be supposed that a man's responsibility for the consequences of his acts varies as the remedy happens to fall on one side or the other of the penumbra which separates trespass from the action on the case. And the greater part of the law of torts will be found under one or the other of those two heads.英文原著 · 《The Common Law》
