Soldier of Fortune may be a heavily LARP-y magazine, and those that read it tend to be mall ninjas more often than not. I should know, because I am a LARP-y mall ninja. Here, however, we find a decent book dressed up in a bit of a clickbait title. In any case, Barry has written books on survival and other subjects that one picks up in the British SAS and this one is a very decent handbook on all things disappearance.
Understanding how the pursuit functions is useful, and is expanded upon in the first half of the book. Several different options are discussed, primarily being split into national and international disappearance strategies. International disappearance is quite tricky and the book can't hope to sufficiently expand on the intricacies of a process like that - I don't think any book can. However, it more than makes up for it in the domestic disappearance approach.
Essentially, one can become a hobo and live off the grid for pennies a day. The book goes into how to do this and what the authorities and world will be trying to do while you're gone. The expression that "traces of you are gone within 7 years" rings more true if you're attempting to clean them up yourself, but even if one is not prepared to begin a new life - the book explains how to enjoy hobo existence.
All of the tips are nuggets I knew of myself and practiced them in limited scope within my own life, without trying to disappear. I strongly recommend this book for people in Russia, Brazil, Indonesia, India, and most of Africa - it's much easier to employ in these countries and works more often than not. Highly functional piece.
