Suggest me a book like the Egypt Game, Mixed Up Files of Basil E Frankweiler, or Harriet the Spy. Imaginative girlhoods, with an undercurrent of a mystery. bonus points for spooky, autumnal, main character coded as gay, set in the 20th century, any mentions of sandwiches wrapped in wax paper, or illustrations. doesn't have to be a children's or young adults' book!!
