When authors give shout outs to other great works, people, and events, it's usually not accidental. Put on your super-sleuth hat and figure out why.
Possible Inspirations
There are no direct references to other novels in Harry Potter and the Goblet of Fire, although J.K. Rowling has mentioned reading (among others) Enid Blyton, Paul Gallico, and Elizabeth Goudge as a child (source). She also likes Jacqueline Wilson, David Almond, Aidan Chambers, Henrietta Branford, and Philip Pullman (source).
