The narrator repeatedly emphasises the fact that "Marley was dead", perhaps to heighten the effect of the appearance of his Ghost. Marley's Ghost is described as being chained with "cashboxes, keys, padlocks, ledgers". This is significant as the things that Marley created in his life become the things which keep him trapped in the afterlife. This has a didactic purpose as Dickens is trying to illustrate to the reader, through supernatural means, that the way they live their lives dictates their eternal resting place.
