Many of the members of the Inklings wrote regular book reviews for publishing and literary journals. They frequently wrote glowing reviews for each others works to help them along. C.S. Lewis praised Tolkien. Tolkien pulled strings for Lewis, and so forth. From Charles Williams though, he was sometimes more likely to find a review like this one for The Screwtape Letters:
My dearest Scorpuscle: It is a dangerous book, heavenly-dangerous. I hate it, this give-away of hell.’ He signed the review ‘Your sincere friend, Snigsozzle’, and added as a postscript: ‘You will send someone to see after Lewis? – some very clever fiend?’
