Darn Dickens! The deeper I go into the Christmas Carol text, the more irregularities I find.
When Marley’s ghost tells Scrooge to expect the three ghosts, he says:
“Expect the first tomorrow, when the bell tolls One. Expect the
second on the next night at the same hour. The third upon the next
night when the last stroke of Twelve has ceased to vibrate.”
But in the next stave, when the Ghost of Christmas Past appears, Scrooge says:
“Twelve? It was past two when I went to bed. Why, it isn’t
possible that I can have slept through a whole day and far into
another night? It isn’t possible that anything has happened to the
sun, and this is twelve at noon. “
The next two ghosts arrive “on time”..but this one was apparently a bit early…
