You've got blackmail by Rachel Wright
A laugh out loud story about Loz, who with her boyfriend, Dex, try to track down a blackmailer, extorting money form their despised teacher, Mr Barnett. The letter, opened in error, has clues that they follow to hunt down the person involved. But trying to keep the detective work quiet, when the teacher concerned is going out with her mum, and Dex's little brother thinks he is a spy, and Loz's older sister screams for England, and your father has just left home, and the suspected blackmailer works for mum, then things are a little complicated.
Quirky, hilarious and brimful of wonderfully eccentric characters, You've got blackmail is sure to tickle the sensibilities of upper primary and lower secondary pupils.
