Kama Sutra
From Tardis Wiki, the free Doctor Who reference
The Kama Sutra was a manual of sexual tactics. The original version of the book was written in Sanskrit; it continually hinted at demons which could be summoned by carelessness or malice. The first English translation of the book was produced in Medmenham; it contained no mention of demons.
Lisa-Beth Lachlan read the Kama Sutra. (PROSE: The Adventuress of Henrietta Street)
