Hook began constructing crosswords at age 14, when he sent a rebuttal crossword to Eugene T. Maleska. Maleska's crossword contained the hidden message:
You Have Just Finished The World's Most Remarkable Crossword
Hook's crossword contained the hidden message:
What Makes You Think Your Puzzle Is More Remarkable Than Mine[2]
In the mid-1980s, he collaborated with novelists Patricia Moyes and Herbert Resnicow to create crosswords for crossword-themed mystery novels.[3]
In 1990, CROSSW RD ranked his Hooked on Puzzles #3 the best book of the year;[4] Hook subsequently recused himself from future awards.[5]
Stanley Newman has described one of Hook's puzzles as "one of the toughest crosswords (Newman) has ever published".[6]
Matt Gaffney, the crossword constructor for Slate.com, described meeting Hook as being like "meeting Elvis",[7] while Will Shortz called him "ingenious, (and) a truly brilliant puzzlemaker."[8] Crossword editor and historian Ben Tausig, in his 2013 The Curious History of the Crossword, described Hook as "an under-recognized, polarizing genius with a sometimes tense relationship with audiences."[9]
Hook died on October 27, 2015, after a long illness.[10][11]
