Open research question
Trace the earliest contemporary sources for the Black Monk case and establish the documented activity period. Determine whether reports continued into 1969 or ended in 1968. Compare early records of knocking, object movement, apparitions and physical interactions with later books, articles and documentaries to identify details added through retelling.
A source, research note, or further-reading link closes this question when staff accept it. Evidence and corrections stay attached for staff and do not close it by themselves.
Staff review every contribution before it is added to the file. A correction is a proposal: accepting it does not replace the official record. Rejected items are handled like rejected case submissions.
