The book by the largest American Nabokov scholar Donald Barton Johnson is devoted to the analysis of the main motifs running through all of V. Nabokov’s novels, such as anagrams, chess problems, the theme of doubles and “mirror” reality. The book remains to this day one of the most authoritative monographs dedicated to Nabokov’s work, serves as the most important source for specialists, and allows the general reader to trace the “internal patterns” of the novels of one of the greatest writers of the 20th century.
