Up to the end of chapter 10 now, and we've moved into the territory also covered by Edward's short story anthologies: Serpents in Eden (countryside crimes), Murder at the Manor (country house crimes), Capital Crimes (London mysteries) and Resorting to Murder (detectives solving crimes while on vacation), and finally, Making Fun of Murder (books satirizing the genre -- so far, not also the topic of a short story anthology).
I'd been planning to create one single "other books mentioned" list for all five of these chapters, but it turns out Edwards really went overboard on this one ... so I ended up with an 80+ book list just for chapters 6 and 7 (the two countryside chapters):
-- with further lists to be created for the next chapters separately.
