On the basis of reliable documentary materials the author of book, research worker of МГИМО Olga Nikolaevna Четверикова, comes to the sensational conclusions: since 1933, the apex of the Римско-католической church begins to depart from fundamental principles christianities and moreover - actively tries under the guise of "modernisation of church" to substitute these principles other, to christianity straight hostile. As most simple catholics about these processes knows nothing, an author sees in what be going on the plot of dads and cardinals against the Римско-католической church. "Treason in Vatican" of О. Четвериковой is a sharp and enthralling publicism. Although books on this theme already went out in the west, in Russia about it to Четвериковой nobody wrote.
