The Wallaby Detectives and the Tomato Sauce Mystery

Maggie from Maggie's Pie Shop is in a terrible flap! It's almost lunch time and the tomato sauce delivery hasn't arrived! Sherlock Mycroft and Watson Wallaby the world's smartest detectives are on the case. Why hasn't Wally Wombat delivered the sauce? Where is Wally? What are the suspicious red splotches near Ms Dingo's house? Is the chocolate-cherry-caramel-coconut cake really an important clue or does it just smell like one? Is a meat pie without tomato sauce really a crime anyway? If Watson Wallaby can keep his brothers working on the case these questions will be answered and the Wallaby Detectives will save lunch.
