This book was passed down to me from my mum since I was 10 years old.
Always loved and hated reading its stories because they were fascinating and horrifying at the same time.
Turned to page 367, I found the Hodgeson's story, titled "Knock Twice for Terror".
If you are unfamiliar with the Hodgeson's case in Enfield, London, it was the haunting case that is the main story for The Conjuring 2.
Although some of the names of the spirits varried from the movie's and this book's. The story is no less than eerie and violent than depicted, although maybe a bit milder in the movie.
In the movie, Janet alone was possessed by a spirit named Bill Wilkins, and a demon named Valak.
