A Disappearance is a 1910 pamphlet with paranormal properties. It is barely twelve pages long.
If read cover to cover, it removes the reader from the world. Reading one or two words can hide the reader from sight, even supernatural sight.
Caused the disappearance of Jacob Feng, an assistant of Jurgen Leitner, who was never seen again.
In MAG 80, Leitner details using the pamphlet to hide from Elias Bouchard while working with Gertrude Robinson and living in the old Millbank Prison tunnels. It is not known what happened to it after Elias murdered Leitner.
