Betrayal: Whitey Bulger and the FBI Agent Who Fought to Bring Him Down

By Robert Fitzpatrick with Jon Land. According to Michael and Dorothy, who gave the book to a previous owner, it's "a great story about how things are not what they seem to be[;] good reading." It's basically the book version of The Departed from the DiCaprio POV.  The paperback's in good shape: uncracked spine, some shelfwear and very mild page toning.
