According to a quote from Madeleine L'Engle found in Madeleine L'Engle Herself, C.S. Lewis was noted to work on two books at a time, one fictional and one theological in genre. Does anyone know which theological manuscript he was working on at the same time as Prince Caspian? I have looked at several bibliographies of his works, however publishing dates are not necessarily indicative of when he was actually writing the manuscript.
Thank you for your help,
