Dick Francis Reading Group discussion

I recently read Madeleine L'Engle Herself: Reflections on a Writing Life and was very pleased to read this in part where she talked about what she likes to read:

“I also read English murder mysteries. Dick Francis writes about horse racing. I couldn’t care less about horse racing; however, Francis deals with decency in human nature, and not many writers deal with decency anymore. Then of course I always go back to my great old favorites—Marjorie Allingham, Dorothy Sayers, Ngaio Marsh, and Josephine Tey—because good books are worth reading any number of times."
