I believe that there's an interview with AF somewhere on the internet - yes, here (http://www.maulu.demon.co.uk/AF/author/interview95.html) in which Sue Simms "mentioned that I'd always felt it to be a slight discrepancy that Patrick seems to be an Anglican in Falconer's Lure (at least, he has a cousin who is a vicar), but emerges as a fully-blown Catholic, complete with aristocratic recusant ancestors, in End of Term. Was this because she had become a Catholic in between the two books? No -- again, I'd failed to take the needs of an author into account. "I actually became a Catholic in 1947, considerably before either of those two books were written. I wasn't thinking about Catholicism in Falconer's Lure; but in End of Term, the Christmas play needed to be described from the point of view of the audience. The trouble was, I didn't know the proper Anglican vocabulary -- so Patrick became a Catholic!"
