The Screwtape Letters by C. S. Lewis, John Cleese (Read by)
I've lost count of the number of times I've read (or listened to) this priceless book. It is delightful - and I consider "devotional" in how, through the perspective of the demon Screwtape, we poor sinners get a much better picture of the spiritual warfare that is our earthly lives. And, as I've perhaps noted before, I enjoy reflecting on where my father was when he first read it - in a German POW camp.
This audio reading by John Cleese is excellent. His reading - his ACTING - of Screwtape's words is spot on. I've done readings from this myself, but none since hearing Mr Cleese - I'm sure he'll influence me greatly, should I get another opportunity to perform fromt this classic.
(the library links above may not lead you to the unabridged Cleese reading -I'd recommend searching "by words," to find it).
