 A British study published in 1996 found 62 cases of alleged ritual abuse reported to researchers by police, social and welfare agencies from the period of 1988 to 1991, representing a tiny proportion of extremely high-profile cases compared to the total number investigated by the agencies.Anthropologist Jean LaFontaine spent several years researching ritual abuse cases in Britain at the behest of the government, finding that all of the cases of alleged satanic ritual abuse that could be substantiated were cases where the perpetrators' goal was sexual gratification rather than religious worship.Producing several reports and the 1998 book "Speak of the Devil", after reviewing cases reported to police and children's protective services throughout the country LaFontaine concluded that the only rituals she uncovered were those invented by child abusers to frighten their victims or justify the sexual abuse.
