The Picture Clue books are based on the traditional "rebus Reader" - using a picture as a tool for learning a word. On the sample spread, you can see where a picture is substituted for a word. This gives a young reader a sense of pride that she is "reading" the story. All pictures and vocabulary are on flashcards at the end of the book. Scooby and Shaggy are all alone on a dark and stormy night. They think that there's a monster in the house, but it looks more like a mystery!
