Like Tom and Sophy Traddles, Charles and Catherine Dickens often had relatives living with them. Dating from the end of their honeymoon, they almost never lived alone. A succession of relatives came to reside with them, including Catherine’s sisters and Charles’ younger brother, Frederick Dickens. It's a wonder Dickens ever got any work done!

Many of Dickens' characters seek to distil time by keeping rooms as they were at some desired point in the past. Nurse Peggotty keeps a room for David just as he left it, as does Agnes. Most famously, of course, Miss Havisham keeps the reception room as it had been prepared just prior to her wedding.

From the Book of Genesis. The Tower was said to have been built in Babylon for the glory of man; God, displeased by this intent, confused all the languages of its people so that communication between them became a confused and raucous affair. Click here to read more.
