If you search for [queens of crime] you’ll turn up four names: Agatha Christie, Dorothy L. Sayers, Ngaio Marsh, and Margery Allingham. They’re all leading lights from the Golden Age of Detective Fiction.
I’ve known about and read Christie and Sayers since grade and high school, respectively. I’d seen Ngaio Marsh’s name many times over the years but don’t recall ever seeing Allingham’s. Recently I’ve worked through Marsh’s oeuvre. Now I’m exploring Allingham’s.
I’m also working through another queen: Ellery Queen.
