Michelle Remembers is a discredited 1980 book co-written by Canadian psychiatrist Lawrence Pazder and his psychiatric patient (and eventual wife) Michelle Smith.[1] A best-seller, Michelle Remembers relied on the discredited practice of recovered-memory therapy to make sweeping, lurid claims about satanic ritual abuse involving Smith that contributed to the rise of the Satanic ritual abuse moral panic in the 1980s.[2][3]
While the book presents its claims as fact, and was extensively
marketed on that basis at the time, no evidence was provided; all
investigations into the book failed to corroborate any of its claims,
with investigators describing its content as being primarily based on
elements of popular culture and fiction that were popular at the time
when it was written.[4][5]
