What Is 'Pale Fire'?

“Pale Fire, a poem in heroic couplets, of nine hundred ninety-nine lines, divided into four cantos, was composed by John Francis Shade (born July 5, 1898, died July 21, 1959) during the last twenty days of his life, at his residence in New Wye, Appalachia, U.S.A. The manuscript, mostly a Fair Copy, from which the present text has been faithfully printed, consists of eighty medium-sized index cards, on each of which Shade reserved the pink upper line for headings (canto number, date) and used the fourteen light-blue lines for writing out with a fine nib in a minute, tidy, remarkably clear hand, the text of his poem, skipping a line to indicate double space, and always using a fresh card to begin a new canto.” Read these lines before?
