Finding a dead body at my new school was a pretty rubbish way to start. But actually getting mixed up in the case? I was bound to get into deep, deep trouble for that!

Murder comes to Hanbridge High, and three Year Seven misfits want to solve the crime:

New boy Jonno hopes playing detective will convince his parents that moving to Hanbridge was a big mistake.

School reporter Lydia thinks her news story will sweep everything else off the front page.

And young carer Daniel needs the police to arrest the right culprit - for his mum's sake.

They may not be friends, but they’re about to become... The Detention Detectives.
