Sybil, or the Two Nations by Benjamin Disraeli

At the end of a court in Wodgate, of rather larger dimensions than usual in that town, was a high and many-windowed house, of several stories in height, which had been added to it at intervals. It was in a most dilapidated state; the principal part occupied as a nail-workshop, where a great number of heavy iron machines were working in every room on each floor; the building itself in so shattered a condition that every part of it creaked and vibrated with their motion. The flooring was so broken that in many places one could look down through the gaping and rotten planks, while the upper floors from time to time had been shored up with props.

This was the Palace of the Bishop of Wodgate, and here with his arms bare and black, he worked at those locks, which defied any skeleton key that was not made by himself. He was a short, thickset man, powerfully made, with brawny arms disproportionately short even for his height, and with a countenance, as far as one could judge of a face so disfigured by his grimy toil, rather brutal than savage. His choice apprentices, full of admiration and terror, worked about him; lank and haggard youths, who never for an instant dared to raise their dingy faces and lack-lustre eyes from their ceaseless labour. On each side of their master, seated on a stool higher than the rest, was an urchin of not more than four or five years of age, serious and demure, and as if proud of his eminent position, or working incessantly at his little file; -- these were two sons of the bishop.
