'I'm glad you liked 'The Lion'. A number of mothers, and still more, schoolmistresses, have decided that it is likely to frighten children, so it is not selling very well. But the real children like it, and I am astonished how some very young ones seem to understand it. I think it frightens some adults, but very few children ...'
CS Lewis in Walter Hooper (Ed.), The Collected Letters of CS Lewis Vol III, p.93.
