Fog occurs naturally in San Francisco: fog not unlike fog that engulfs San Francisco's Alcatraz Island, where Rodrigo Garcia Olza mysteriously arrives underwater. Many so-called vampires worldwide are really demons. At least for this island, many theologians propose that that demons created vampires by entering and animating corpses the Ohlone Indians buried on Alcatraz Island. When Spain's explorers intruded upon the ancient burial grounds the natives avoided, many of the dormant evil spirits were awakened and have yet to be quieted - despite valiant efforts through the centuries. To compound an already looming festering problem, after the Spaniards desecrated the Ohlone burial grounds, the village chief cursed Alcatraz Island so no white man can ever live there. (It is no coincidence that the Alcatraz Federal Penitentiary was abandoned in 1963 after only 30 years.) Vampire Rodrigo Garcia Olza initially realizes he landed in San Francisco to eradicate one of the Earth's most ancient and powerful demons (a vampire) born out of sorcery in ancient Mesopotamia/Rome, summoned into this earthly plane from some other realm. A morgue on Alcatraz Island has no history of use but appears to harbor secrets, including a mysterious possible connection to Purgatory. A world renowned San Francisco independent filmmaker casts Rodrigo in a film adaptation of Federico Garcia Lorca's "The Butterfly's Evil Spell," with Alcatraz Island as its location. Later Rodrigo discovers his more complicated purpose: freeing Spain's greatest poet and dramatist, Federico Garcia Lorca from Purgatory. In the process of solving two separate profound mysterious, he discovers both are linked. Rodrigo collaborates with two companions to solve the missing pieces of two puzzles of related phenomena -- foremost San Francisco fashion photographer Liam Mannering, and Audrey Hepburn "Breakfast At Tiffany's" doppelganger, Holiday Dampiere.
