Death Among the Marshes is quite short — more a novella than novel — and essentially a modern take on the Golden Age staple of a country house mystery. The detective, Freddie, bears some resemblance to Sayers’ Lord Peter, in his aristocratic ties, his war-buddy turned valet, etc, and indeed Ramage references Freddie reading Dorothy Sayers’ work, which made me smile.
Unlike the Golden Age country house mysteries, though, this novella is quite frank about the existence of gay people; one couple come under suspicion as their family tries to put a wedge between them and persuade them to be more socially appropriate, and there are possible hints that Billy, Freddie’s manservant, might have feelings for him. All the characters are well-drawn and, if not exactly likeable, understandable in their support of each other, their squabbles, their faultlines.
I found Death Among the Marshes enjoyable and well-structured, and I’ll definitely read any other books by Ramage which feature these characters. This review does more justice to it than mine, I think!
