''Mr Chartwell'' is so startlingly original that's it's difficult to recommend further reading. Books which look at mental illness are not usually so hilariously funny and books with a large talking dog as the main character are not generally quite so thought-provoking. For a factual look at the way a large dog turned one man's life around we can recommend [[I Have Heard You Calling In The Night by Thomas Healy]]. For the true story of someone else who encountered the black dog have a look at [[Shoot the Damn Dog by Sally Brampton]].
