The Da Vinci Code
The Da Vinci Code is a 2003 mystery-detective novel by Dan Brown.
 It follows symbologist Robert Langdon and cryptologist Sophie Neveu after a murder in the Louvre Museum in Paris, when they become involved in a battle between the Priory of Sion and Opus Dei over the possibility of Jesus Christ having been a companion to Mary Magdalene.
 The title of the novel refers, among other things, to the finding of the first murder victim in the Grand Gallery of the Louvre, naked and posed similar to Leonardo da Vinci's famous drawing, the "Vitruvian Man", with a cryptic message written beside his body and a pentacle drawn on his chest in his own blood.
Bestseller
A bestseller is a book that is included on a list of top-selling or frequently-borrowed titles, normally based on publishing industry and book trade figures and library circulation statistics; such lists may be published by newspapers, magazines, or book store chains.
 Some lists are broken down into classifications and specialties (number one best selling new novel, nonfiction book, cookbook, etc.).
 An author may also be referred to as a bestseller if their work often appears in this category.
 Well-known bestseller lists in the U.S. are published by "Publishers Weekly", "USA Today", "New York Times" and the "Washington Post".
 Most of these lists track book sales from national and independent bookstores, as well as sales from major internet retailers such as Amazon.com and Barnes & Noble. Tad Hills

The One Ring is an artefact that appears as the central plot element in J. R. R. Tolkien's "The Lord of the Rings" (1954–55).
 It is described in an earlier story, "The Hobbit" (1937), as a magic ring of invisibility.
 In the sequel, "The Lord of the Rings", Tolkien ascribes to the Ring a darker character, with malevolent power going far beyond conferring invisibility: it was created by Sauron the Dark Lord as part of his design to win domination over Middle-earth.
 "The Lord of the Rings" concerns the quest to destroy the Ring to keep Sauron from fulfilling his design. Alfred Kropp series
