Haunted House by Charles Dickens?
Please be more specific about the information you need.
Charles Dickens didn't work at a poor house. He worked at a blacking factory owned by Charles Lamert while his father was imprisoned at Marshalsea Debtor's Prison (a poor house). Charles' father, mother and four of his siblings lived at Marshalsea with John Dickens, while Charles continued to work at the blacking factory while living in a rented attic space a few miles away.
Bleak House is the Charles Dickens' ninth novel, published in installments between March 1852 and September 1853. The setting lies mainly in the fictional Chesney Wold of London. The plot is about a long-running legal dispute with consequences for all involved; it is doubly a critical analysis on the British judicary system by Dickens.
