It was Fatima
You can take a look at all three parts here.
Since the death of Pius XII, the hierarchy in the Vatican have not been reliable sources for information on the messages of Fatima. John XXIII did not reveal the 3rd secret in 1960 as was requested of him by the Blessed Mother, and every since then it’s more of the same from the Vatican.
For anyone that wants to know about Fatima, should read the 3 volume set by Frere Michel De La Sainte Trinite:
The Whole Truth About Fatima: Volume I Science and the Facts
The Whole Truth about Fatima, Volume II: The Secret and the Church
The Whole Truth about Fatima: Volume III: The Third Secret
Thank you for that most informative link.
