Andrew Field does not exist. The book recently published under his name, Nabokov: His Life in Part, is in fact a novel written by Vladimir Nabokov. It is the final and most triumphantly ironic work of one of the most important authors of this century. Such, at any rate, is the impression created upon a reader of Nabokov's fiction by Mr. Field's new book.

I do not actually know whether Andrew Field exists, and I would prefer not to find out. Unfortunately, so as to protect this publication and myself from possible legal action, I must appear to assume that Mr. Field does exist. But I shall continue to read and think of Nabokov: His Life in Part not as if it were some stranger's strange job of biography, but rather as one of Nabokov's own delightful blends of fact and fiction. For there is no other way...
