Speak of the Devil: Tales of Satanic Abuse in Contemporary England is a scholarly book by J. S. La Fontaine published in 1998 that discusses her investigation of allegations of satanic ritual abuse made in the United Kingdom.

[5] Robin Woffitt of the University of Surrey praised the book for clearly describing the origins of the satanic ritual abuse moral panic in the United Kingdom.

[1] The English archaeologist Timothy Taylor critically discussed Fontaine's work in his book The Buried Soul: How Humans Invented Death (2002).

He compared the work to the anthropologist William Arens's 1979 book The Man-Eating Myth, which he described as a "hollow certainty of viscerally insulated inexperience".

Asserting that Arens's uses a flawed methodology that has echoes of Speak of the Devil, Taylor himself suggests that multiple claims of the Satanic ritual abuse have been incorrectly dismissed for being considered "improbable".
