How many ghosts show up in "A Christmas Carol?"

The four ghosts who appear in the Charles Dickens are Jacob Marley, the ghost of Christmas Past, Present, and Christmas yet to come. The four all visit Ebenezer Scrooge on Christmas Eve.

Marley was Scrooge's business partner and friend who died seven years ago. He appears to his friend as a ghost and tells him there are three spirits who will pay him a visit. Due to Marley's life of greed and selfishness, he's found himself in a bad fate even in death.

The Ghost of Christmas Past takes Scrooge back to his childhood, the Ghost of Christmas Present shows him all the happy people at the market buying food for Christmas dinner and other holiday celebrations when he is alone, and finally The Ghost of Christmas Yet to Come shows the grumpy man his own grave and how no one mourns his loss. But by the end, Scrooge learns to become a kinder person.
