“Before the service was over -- one cd. wish these things came more seasonably -- I was struck by an idea for a book wh. I think might be both useful and entertaining. It wd. be called As one Devil to Another and would consist of letters from an elderly retired devil to a young devil who has just started work on his first ‘patient’.”
Letter to his brother Warnie, July 20th 1940
"I was often asked or advised to add to the original ‘Screwtape Letters’, but for many years I felt not the least inclination to do it. Though I had never written anything more easily, I never wrote with less enjoyment. The ease came, no doubt, from the fact that the device of diabolical letters, once you have thought of it, exploits itself spontaneously... it was not fun, or not for long. The strain produced a sort of spiritual cramp."
