Lucretia, Volume VI by Edward Bulwer-lytton

When Beck woke the next morning, and gradually recalled all that had so startled and appalled him the previous night, the grateful creature felt, less by the process of reason than by a brute instinct, that in the mysterious resuscitation and nocturnal wanderings of the pretended paralytic, some danger menaced his master; he became anxious to learn whether it was really St. John's room Madame Dalibard stealthily visited. A bright idea struck him; and in the course of the day, at an hour when the family were out of doors, he contrived to coax the good-natured valet, who had taken him under his special protection, to show him over the house. He had heard the other servants say there was such a power of fine things that a peep into the rooms was as good as a show, and the valet felt pride in being cicerone even to Beck.

After having stared sufficiently at the banquet-hall and the drawing-room, the armour, the busts, and the pictures, and listened, open-mouthed, to his guide's critical observations, Beck was led up the great stairs into the old family picture-gallery, and into Sir Miles's ancient room at the end, which had been left undisturbed, with the bed still in the angle; on returning thence, Beck found himself in the corridor which communicated with the principal bedrooms, in which he had lost himself the night before.
