The poisoned arrow - Simon Cheshire

What kind of dirty tricks are being played at the local theatre? Why would someone take the blame for a crime they couldn't have committed? And how do the top team in the school quiz seem to know the answers before they hear the questions?
Solve three more mind-mangling mysteries, brought to you by Saxby Smart, schoolboy private detective. Saxby reveals the clues that solve the cases, but are you smart enough to work out them out for yourself?
