Case 01

The Voice in the Blue Room

A live-streamed séance. A host who dies at the table. And a voice that should not exist.

The police call it natural causes. His sister does not. Step into Vantry House, a clifftop mansion with too many locked doors, and find out who wanted him silent. Every clue is findable. Every suspect has something to hide. Nobody is going to hand you the answer.

How it plays

Think like a detective

No hand-holding. Just a house, its people and the things they left behind.

Examine

Walk through every room and look closer. Letters, logs, bottles and locks all hold a piece of the night.

Interrogate

Talk to everyone. Show them what you have found and watch who flinches, who confesses and who lies better.

Deduce

Everything you learn lands in your notebook. Connect the clues into deductions until only one story fits.

Your pace

Stuck? Ask for a hint. Confident? Switch on Expert mode and the interaction markers vanish.
