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.
Books in the Cthulhu Mythos Many fictional works of arcane literature appear in H.P. Lovecraft's cycle of interconnected works often known as the Cthulhu Mythos. The main literary purpose of these works is to explain how characters within the tales come by occult or esoterica (knowledge that is unknown to the general populace). However, in some cases the works themselves serve as an important plot device. Thus, in Robert Bloch's tale "The Shambler from the Stars", a weird fiction writer seals his doom by casting a spell from the arcane book "De Vermis Mysteriis".
