Georgette Heyer was my first mystery writer - I got there through her Regency romances (stop it; everyone is a teenager once). It had been a long time since I'd read "Unfinished," and I was delighted all over again by the numerous characters, not one of whom could one mistake for another, the ridiculous house party, the clear-eyed heroine, and the detective, whom we do not meet until far into the book.
