I don’t quite understand people who like Marsh’s books as much as, say, Dorothy L. Sayers’. Alleyn just doesn’t have the same depth of characterisation as Wimsey, and while the character of Troy is quite fun, she doesn’t seem to have come into it as much as Harriet. It is true that Wimsey books go buy without Harriet, though usually there’s Parker and Bunter, the Dowager Duchess and plenty of other supporting characters who pop up repeatedly. In these books, it seems to often be just Alleyn and Fox, and the possibilities of that partnership are limited.
The mystery itself is… okay. It takes some time to build up a set of characters to theorise about first (though I hope they’re not intended to be likeable as such, because most of them are not), which at least adds a bit of interest; I do like the way crime/mystery stories can be used as a character study. I found the ending ridiculously drawn out; enough red herrings, let’s have the culprit, please.
I think Ngaio Marsh’s books, properly spaced out, will keep me entertained well enough, but I’m probably going to avoid reading them back to back. They’re just too dry, and Alleyn isn’t enough of a person to me.
