I just finished The Big Over Easy by Jasper Fforde about Humpty Dumpty's murder and the Nursery Crime Division Detective (Jack Spratt) who solves the crime. I loved that it was quirky and blended realistic and nursery rhyme characters.
My daughters are reading a book called The Sisters Grimm: The Fairy Tale Detectives, which sounds like it did a bit of the same blend of realistic and fairy tale characters. (it's for Battle of the Books)
Anyone else enjoy books like this? Any suggested titles? (something like Ella Minnow Pea is kinda like this to me, too)
