As this was no business of Mr Swiveller's, the person not ringing the office bell, he pursued his diversion with perfect composure, notwithstanding that he rather thought there was nobody else in the house.
In this, however, he was mistaken; for, after the knock had been repeated with increased impatience, the door was opened, and somebody with a very heavy tread went up the stairs and into the room above.

Mr Swiveller was wondering whether this might be another Miss Brass, twin sister to the Dragon, when there came a rapping of knuckles at the office door.

The business will get rather complicated if I've many more customers.
