The timeline absolutely doesn't, but I truly believe "I want to marry you, if you can put up with me and all that" / "That makes forty-seven, but I admit I've never been proposed to by a dead man before; that at least has the air of novelty" has legs and if Dorothy had the courage of her convictions she could have run with it! (No offense to Strong Poison as it is, already in and of itself a delightful book of course.)
