She produced from her pocket a steel ring, with several keys attached to it. “A duplicate of Mr. Farnaby’s key,” she explained, as she chose one, and opened the street door. “Sometimes, when I find myself waking in the small hours of the morning, I can’t endure my bed; I must go out and walk. My key lets me in again, just as it lets us in now, without disturbing anybody. You had better say nothing about it to Mr. Farnaby. Not that it matters much; for I should refuse to give up my key if he asked me. But you’re a good-natured fellow--and you don’t want to make bad blood between man and wife, do you? Step softly, and follow me.” Amelius hesitated. There was something repellent to him in entering another man’s house under these clandestine conditions. “All right!” whispered Mrs. Farnaby, perfectly understanding him. “Consult your dignity; go out again, and knock at the door, and ask if I am at home. I only wanted to prevent a fuss and an interruption when Regina comes back. If the servants don’t know we are here, they will tell her we haven’t returned--don’t you see?” It would have been absurd to contest the matter, after this. Amelius followed her submissively to the farther end of the hall. There, she opened the door of a long narrow room, built out at the back of the house. “This is my den,” she said, signing to Amelius to pass in. “While we are here, nobody will disturb us.” She laid aside her bonnet and shawl, and pointed to a box of cigars on the table. “Take one,” she resumed. “I smoke too, when nobody sees me. That’s one of the reasons, I dare say, why Regina wished to keep you out of my room. I find smoking composes me. What do _you_ say?” She lit a cigar, and handed the matches to Amelius. Finding that he stood fairly committed to the adventure, he resigned himself to circumstances with his customary facility. He too lit a cigar, and took a chair by the fire, and looked about him with an impenetrable composure worthy of Rufus Dingwell himself.
