Title: The Saint (novel)
Content:  The Saint is a mystery novel by Burl Barer published by Pocket Books in 1997. It was based upon the screenplay for the film The Saint, which in turn was loosely based upon the character Simon Templar, created by Leslie Charteris. Val Kilmer portrayed Templar and is pictured on the book's front cover. This was the first book featuring Templar since Salvage for the Saint ended the original series of books (which began in 1928) in 1983. It is also the first Saint story to be published since Charteris' death in 1993 and the first to not be published by either Hodder & Stoughton (UK) or The Crime Club (US). Barer wrote the book based upon the screenplay by Jonathan Hensleigh and Wesley Strick. Barer himself 
Title: The Saint (Simon Templar)
Content:  Most Saint books were collections of novellas or short stories, some of which were published individually either in magazines or in smaller paperback form. Many of the books have also been published under different titles over the years; the titles used here are the more common ones for each book. From 1964 to 1983, the Saint books were collaborative works; Charteris acted in an editorial capacity and received front cover author credit, while other authors wrote these stories and were credited inside the book. These collaborative authors are noted. (Sources: Barer and the editions themselves.)
Title: Vendetta for the Saint
Content:  The novel is credited to Leslie Charteris, who created the Saint in 1928, but the book was actually authored by Harry Harrison, a noted science fiction author who also wrote the syndicated Saint comic strip. Although Harrison wrote the majority of the book as a ghost writer, he indicates in an interview that Charteris did contribute to the final book (albeit in a very minor way).. The reference work The Saint: A Complete History by Burl Barer, however, indicates that Charteris was heavily involved in editing the book. Vendetta was the first Saint volume published after Charteris chose to step back from actively writing the adventures, and were followed by a number of books credited to Charteris but actually written by other authors. Charteris remained as editor of the books, approving stories and revising material when needed. These books were mostly based upon teleplays from the TV series or scenarios from the comic strip; the next wholly original Saint literary stories were not published until the novella collection Catch the Saint more than a decade later.

Many of these stories were ghostwritten by Madeleine Michel-Tyl and credited to Charteris (who exercised some editorial control). The French books were generally novelisations of scripts from the radio series, or novels adapted from stories in the American Saint comic strip. One of the writers who worked on the French series, Fleming Lee, later wrote for the English-language books.
