In which Dickens novel does Stephen Blackpool appear?

Stephen Blackpool is Charles Dickens' tragic character in "Hard Times".

He is a worker at one of Bounderby's mills. Stephen has a drunken wife who no longer lives with him but who appears from time to time. He forms a close bond with Rachael, a co-worker, whom he wishes to marry. After a dispute with Bounderby, he is dismissed from his work at the Coketown mills and, shunned by his former fellow workers, is forced to look for work elsewhere. While absent from Coketown, he is wrongly accused of robbing Bounderby's bank. On his way back to vindicate himself, he falls down a mine-shaft. He is rescued but dies of his injuries.

"Hard Times" is the tenth novel by Charles Dickens, first published in 1854. The book surveys English society and satirises the social and economic conditions of the era.

"Hard Times" is unusual in several respects. It is by far the shortest of Dickens' novels, barely a quarter of the length of those written immediately before and after it. Also, unlike all but one of his other novels, "Hard Times" has neither a preface nor illustrations. Moreover, it is his only novel not to have scenes set in London. Instead, the story is set in the fictitious Victorian industrial Coketown, a generic Northern English mill-town, in some ways similar to Manchester, though smaller. Coketown may be partially based on 19th-century Preston.
