Dombey and Son by Charles Dickens

Time, sure of foot and strong of will, had so pressed onward, that the year enjoined by the old Instrument-maker, as the term during which his friend should refrain from opening the sealed packet accompanying the letter he had left for him, was now nearly expired, and Captain Cuttle began to look at it, of an evening, with feelings of mystery and uneasiness.

The Captain, in his honour, would as soon have thought of opening the parcel one hour before the expiration of the term, as he would have thought of opening himself, to study his own anatomy. He merely brought it out, at a certain stage of his first evening pipe, laid it on the table, and sat gazing at the outside of it, through the smoke, in silent gravity, for two or three hours at a spell. Sometimes, when he had contemplated it thus for a pretty long while, the Captain would hitch his chair, by degrees, farther and farther off, as if to get beyond the range of its fascination; but if this were his design, he never succeeded: for even when he was brought up by the parlour wall, the packet still attracted him; or if his eyes, in thoughtful wandering, roved to the ceiling or the fire, its image immediately followed, and posted itself conspicuously among the coals, or took up an advantageous position on the whitewash.
