Viktor Suvorov , author of '' Icebreaker '' said that the book is " Terrifying , gripping and instructive " . According to Suvorov : Former Soviet prisoner of conscience Vladimir Bukovsky stated , " Litvinenko eloquently depicts that what was long considered to be the ' shield and sword ' of the communist party is in reality a huge criminal mechanism " . As Andrei Antonov writes , " the way Litvinenko sees it , the FSB is clearly a criminal and even terrorist organization . And not only because of apartment explosions or alleged conspiracy against Berezovsky . Litvinenko is certain that security services were behind the murder of Galina Starovoitova , a prominent figure in Russia 's democracy movement , and the death of Anatoly Sobchak , and many , many other things . " Alan Cowell praised the book as an important source that described the attempted assassination of Boris Berezovsky in Moscow and many other events
