Here was the excuse that I had made for her (when she forgot herself before Superintendent Seegrave, on the previous day) being made for her over again, by a man who couldn't have had my interest in making it—for he was a perfect stranger! A kind of cold shudder ran through me, which I couldn't account for at the time.
