Books by Bethany Walker

There's more to Mia's school than meets the eye: rumours say a "lost" version of the Mona Lisa is hidden somewhere inside the building! Scheming criminals are hiding among the teachers, and even her parents are acting weird: with new courses in acrobatics and dressing in tight, black jumpsuits. But are they thieves? Bah, that's ridiculous!

10-year-old Freddy Spicer writes letters to his parents - who he believes are working at a Brussels-sprouts farm in Outer Castonga, with no internet or phone access. In fact, Freddy's parents are secret agents out of the country on a highly classified mission - but Freddy has NO IDEA!
