This doublecrostic can be solved by answering each of the clues A through P, and inserting letters of the individual answers into their corresponding place in the grid. Working backward, placed letters in the grid might reveal patterns that suggest words that can then be used as clues to unknown answers of A through P, thereby completing the puzzle.
The answers A through P are:
A, Cantaloupe; B, Textile; C, Quoted; D, Piciformes; E, Palfrey; F, Igor Stravinsky; G, Outfield; H, Heath; I, Fluent; J, Glass Menagerie; K, Halyard; L, Quotient; M, Cthulhu; N, Tenth; O, Omar Sharif; P, Divinity
The revealed quotation reads: “I have occasionally had the exquisite thrill of putting my finger on a little capsule of truth and heard it give the faint squeak of mortality under my pressure.”
This remark was made by the author of Charlotte’s Web, Stuart Little and other books, E.B. White or Elwyn Brooks White – his full name asked for in the puzzle.
