Something strange is happening at Laverhill Secondary School.
A locker that shouldn't exist begins sending messages.
A student is found trapped inside - and nothing about it feels accidental.
After the events of The Missing Teacher, the Midnight Six aren't looking for another mystery. But when systems start behaving strangely and adults rush to blame the wrong person, Christian and his friends realise someone is quietly manipulating the school from the inside.
As pressure builds and a false suspect emerges, the group must investigate without drawing attention, relying on observation, logic, and trust rather than force. Every mistake tightens the net - and every silence feels deliberate.
Told as one continuous, fast-moving story, The Talking Locker is a smart middle-grade mystery about control, hidden systems, and what happens when information is used as a weapon.
Book 2 of The Midnight Six series.
