The most serious and sourced book ever published on the subject of UAPs (Unidentified Anomalous Phenomena), previously known as UFOs (Unidentified Flying Objects). Written by one of the UK's most high-profile and well-respected barristers who has researched the issue for 50 years

For five decades, Jonathan Caplan KC (King's Counsel) has been pulling together an extraordinary body of evidence about the existence of UAPs, and what he believes to be the world's greatest ever cover up. Public perception of the UAP issue changed radically in July 2023 when David Grusch - a former Air Force intelligence officer - went public to US Congress under oath on live television that the United States was in possession of crashed non-human craft. His evidence ignited huge interest around the world. Pressure is mounting for the full story to be told, and Not For Disclosure is a landmark book on a subject that the public can no longer ignore.

In his quest for the full story, Caplan has travelled over the years to meet inside sources, including scientists, politicians, intelligence officers and ex special forces, in Washington, Israel and elsewhere. He has collated a vast amount of material from those in official positions who have trusted him and who have been prepared to talk confidentially about the subject. Over the last fifty years he has met and befriended most of the key individuals. His book is a detailed, up to date and in many ways shocking account of this fundamental and disturbing subject. It pulls together the strands of the phenomenon. It raises the debate.

The book includes significant new material including information about JFK and also about secret meetings held by President Truman and Secretary Forrestal. There will also be important and previously unpublished documents from the 'Majestic 12' group as well as striking new photos.
