Two parcels of fifty copies each of Disappearing were ordered to confidential addresses in London and Brussels. A file was compiled to aid a decision on whether to suppress publication, parts of which were leaked to the Daily Telegraph. Names of the individuals quoted have been redacted. No censorship was ordered.

This is a subversive book that should not receive the breath of publicity. Among other crimes, one can learn how to kill silently, dispose of bodies, hotwire a car, make a Molotov cocktail, fraudulently extract a pension without tax, and evade mechanical and electronic surveillance. These are skills best kept within the purview of government agencies.
Detective Chief Inspector, National Counter Terrorism Security Office

The author is taunting us with his knowledge of the unsolved murders of Juncker and Selmayr. This was a wicked crime. We are dealing with an amoral, calculating, mass murderer. Whether alive or not, he should be investigated and brought to book in name or in person.
Secretariat, European Commission.

The author views the European Union as a wicked organisation, but there is no doubt that he is a celebrant of European culture. Squaring the circle that he inhabits is fundamental to the success of the federal project.
Assistant Secretary, Foreign & Commonwealth Office

I assumed that most of this book was fantasy, but the facts check out. I sensed that the author had been there, from rock climbing to Van Gogh, from flamenco to the Biafran war, from begging in Winchester to travelling through the Sahara. I now think much of the story may be true. It could even mostly be true.
Surveillance officer, The Security Service, charged with finding the author

The book explains how an individual can divest themselves of identity, go off grid and use terrorist-supporting Hawala to move money. Heal’s success is a direct threat to our banking system and a danger to Western civilisation.
Senior Executive Officer, International Monetary Fund, Informal Funds Transfers

Any story that quotes freely from Aeschylus, Ascherson, Bashō, Bowles, Cervantes, Dostoevsky, Eliot, Herodotus, Kant, Larkin, Mandelstam, and a dozen more, must have something going for it.

He snipes at most aspects of European government. If what he says wasn’t so inherently dangerous, I would recommend ignoring this petulant book.
