Georgette Heyer is a reliable comfort read. Her books are breezy, light, and uncomplicated, typically featuring a murder in a country house. As usual, there are two completely different female characters: one practical and organized, and the other totally bananas; their respective love interests; a host of wacky characters/suspects; one completely nefarious character who is so terrible it's obvious that he is a red herring; and the sensible police detective. Everything gets tidied up in the end - the murder is solved, inheritances are rightly restored, and true love prevails.
