Andrei Babikov has published his decipherment of the abandoned "The
Gift-part 2," along with a companion article, in Zvezda 2015
No. 4. In the article, he proposes an entirely new and surprising
timeline for the composition of that text and others of the late
1930s or early 1940s.
Nabokov's fragment has not been made accessible on line (which is
typical for Zvezda's publications of VN texts), but
Babikov's article is.
The article is called "«Дар» за чертой страницы" (The Gift
Beyond the Horizon of the Page), and can be accessed here.
