People love a good mystery. When I worked at the library, we had patrons who literally devoured mystery books, one after another. I myself confess to being a Trixie Belden fangirl in the '70s (Nancy Drew was a bit too uppity for me). The recent "CSI" craze is just a more grotesque manifestation of this same phenomenon.
So there's good news for aspiring editors who love mysteries: A mystery editor has a blog and is talking about what his job is like. Mysterious Matters: Mystery Publishing Demystified has begun a series on "The Days and Nights of an Editor." The writer/editor of this blog is kind of a mystery himself because his "About" page doesn't work. He goes by "Agatho," though. There's great information and excellent writing here. Check it out!
