Master Humphrey's Clock was a weekly periodical edited and written entirely by Charles Dickens and published from 4 April 1840 to 4 December 1841. It began with a frame story in which Master Humphrey tells about himself and his small circle of friends (which includes Mr. Pickwick), and their penchant for telling stories. Several short stories were included, followed by the novels The Old Curiosity Shop and Barnaby Rudge. It is generally thought that Dickens originally intended The Old Curiosity Shop as a short story like the others that had appeared in Master Humphrey's Clock, but after a few chapters decided to extend it into a novel.
