I think this was done very tastefully, lists a select group of culprits (in alphabetical order) yet didn't get too bogged down with details. It included a nice list at the back, books for reference and some trivia.
Marie Antoinette--front and center--but no Anne Boleyn or Mary Queen of Scotts. Oh well.
Since the stories were so summarized, I looked them up on Wikipedia and was promptly directed to Murderpedia.org. This website included contributions by Geoffrey Abbott, as well as much more well-known, modern culprits. Wonderful source of this kind of morbid, juicy information . . . .. . . . . .
