Malachy is probably best known as the brother of Frank McCourt, who wrote the bestselling Angela's Ashes about their dirt-poor Irish Catholic upbringing. They (and their other brothers) have gotten a fair amount of media attention and a couple of documentaries about them have been broadcast recently.
The contributor notes: "Malachy came out with a book of his own called A Monk Swimming, and although I haven't finished it, he has so far referred twice to the fact that he is an atheist."
