The author is very skilful in raising your anxiety with interesting plots to drive you to continue to read. Worth the time and effort :)
p.s.: I don't like the ending. It is a bit anti-climax!
Uno dei migliori romanzi di spionaggio.
Not exactly my type of thing, but it was worth trying: a perfectly built web of intrigue, that keeps the reader in a constant state of anxiety, along the twisting evolutions of a great and astonishing plot.
