"the infamous novel Chuzzlewit"

 In 1842 Dickens visited America for the first time, spending a month in New York City and meeting with President John Tyler in Washington. The trip resulted in two works, American Notes for General Circulation and Martin Chuzzlewit, which is partly set in America. American Notes was controversial as it strongly condemned slavery, and Martin Chuzzlewit likewise provoked outrage for its portrayal of America as an uncivilised wilderness populated by a range of sly or stupid characters.
