"The Enemies of Lucia dos Santos, the Seer of Fatima"

Who were the people or groups that made Lucia disappear?
Why did a woman claiming to be her appear with famous people from the Vatican?

Background info-
The woman, at the age of 10, predicted the greatest public miracle since the Resurrection, was “disappeared,” in one way or another, by forces that would have had the go-ahead from the Vatican.
