博客來A school trip to a London jewellery museum should have been ordinary.
Until the alarm sounds.
The doors close.
And a priceless historical necklace vanishes.
No glass is broken.
No one runs.
And the person responsible is still inside.
Trapped in a sealed museum with teachers, guards, and visitors, the Midnight Six quickly realise this is no ordinary theft. The necklace didn’t disappear in the chaos - it vanished quietly, carefully, while everyone was watching something else.
With no authority and no way to act openly, the six must rely on observation, memory, and logic to uncover the truth - guiding the adults without ever stepping forward themselves.
This time, the mystery isn’t about chasing a suspect.
It’s about noticing what everyone else overlooks.
Smart, atmospheric, and quietly tense, The Locked Museum is a contained mystery that rewards careful reading and sharp thinking - proving that sometimes the most dangerous secrets are hidden in plain sight.
Perfect for readers who enjoy intelligent mysteries, teamwork, and stories that trust the reader to think.
