Short but good

The Moors Murderers: Ian Brady and Myra Hindley Serial Killers (British Criminals #3) - Aeternum Designs, Alan R. Warren

I picked this up after reading a book that mentioned the murders. The book gives a pretty good history of the murders, and the murderers are not glorified. It is a good, complete history. It includes transcripts and when the stories conflict, both stories are given.
