The novels of Charles ens often?

a. ens was very concerned about the conditions of the poor. However, his depiction of life among the poor was usually set in an earlier period than the one he was actually living in. Some of the conditions he wrote about had ceased to exist before he wrote the books. As in Great Expectations for example, where he points out that the conditions in which prisoners are kept in the present (i.e. when he wrote the book) are very different from those portrayed in the novel.
