According to Haverhill's Eagle Tribune, on Wednesday, April 26, 2000 John Bellairs, along with 3 other Haverhill residents, was recognized for his lifetime achievements as an author by being honored in Haverhill's Hall of Fame. In their description of Bellairs' achievements they mention such popular titles as Sister Fidgeta and Dustin Heights.
Perhaps they were referring to Saint Fidgeta and Other Parodies and the fictional locale of Duston Heights?
