This monograph by Special Agent Ken Lanning (1992) is merely a guide for those who may investigate this phenomenon, as the title indicates, and not a study. The author is a well known skeptic regarding cult and ritual abuse allegations and has consulted on a number of cases but to our knowledge has not personally investigated the majority of these cases, some of which have produced convictions. p179[refers to Lanning, K.
