I read an amusing anecdote about him this morning:

When he was awarded the $236,000 MacArthur “genius” grant in 1981, he carried on cutting his own hair and preparing meals on a hot-plate. And he only ever signed 250 copies of his Pulitzer Prize-winning 2006 novel The Road, all of which he gave to his youngest son John. When the boy turns 18, McCarthy said, “he can sell them and go to Las Vegas or whatever”.

I enjoyed The Road. Couldn't get on with any of his others though.
