This is a lot of 11 vintage Travis McGee novels written by John D. MacDonald, along with a science fiction novel. The books are in paperback format and were published by Fawcett. The novels are action-packed crime and thriller stories, set in the 1960s, and intended for adult readers. The lot includes titles such as "The Quick Red Fox," "The Scarlet Ruse," and "The Green Ripper."  Great reading for those who enjoy detective, action novels.
