The Gum Tree Gang and the Mystery at the Old Queenslander
by Marie Seltenrych
The Gum Tree Gang are formed and they become local sleuths as they try to work out mysterious coded messages found at an abandoned Old Queenslander. Will they decipher the notes and rescue their friends from a life of crime, or will they be caught by the criminals and get into very big trouble with their parents? Courage, intelligence and cooperation are the keys they use to catch the crooks.
