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. Master Humphrey appears as the first-person narrator in the first three chapters of The Old Curiosity Shop but then disappears, stating, "And now that I have carried this history so far in my own character and introduced these personages to the reader, I shall for the convenience of the narrative detach myself from its further course, and leave those who have prominent and necessary parts in it to speak and act for themselves."
