Between the years 1843 and 1848, every Christmas (with the exception of 1847), Dickens released what he called a "Christmas Book". These five books are all short works with a "Christmasy" theme and (with the exception of one) a "supernatural" element. The only one well-known today is "A Christmas Carol", but it may surprise people to learn that, until the start of the 20th century "The Cricket on the Hearth" was at least as popular as "A Christmas Carol", if not more so.
The five books are:
A Christmas Carol (1843)
The Chimes (1844)
The Cricket on the Hearth (1845)
The Battle of Life (1846)
The Haunted Man (1848)
