Query: Brilliant bit of bibliography!

I am not a huge fan of mystery or "crime fiction." I usually figure out the end far too soon. I'm often frustrated by the lack of twists and turns. This book was fantastic! Not only was I kept guessing all the way to end, but the end left me smacking my forehead and crying, "Of course! Oh my gosh! That was brilliant!" If you know your fairy tales and your childhood rhymes, you will be in stitches! If you have a mediocre memory of bits and pieces of these childhood writings, you will still greatly enjoy this book! Jack Spratt is a marvelous character, Humpty Dumpty and the rest are tremendous and I can't wait to read more Jack Spratt Investigations!!!
