Ravenscroft's book sent my synapses smoking. It also confirmed my suspicions that the Swastika was a very ancient symbol (having once spied it on a temple in India). This fascinating, frightening book is a must-read. Now I know where film maker Phil Kaufman (who wrote the original story for "Raiders of the Lost Ark" which became a Larry Kasdan screenplay) got the name for the female lead in the picture...remember Marion RAVENwood?
