Paradise has a deadly secret.
A cast of famous quiz show champions arrive on the stunning Trezore Island to compete in a brand-new reality TV quiz, all chasing quiz show glory. But beneath the palm trees, luxury villas and television cameras, old rivalries, hidden motives and dangerous secrets are waiting to surface.
When one contestant is murdered, the competition comes to an abrupt end. With the island cut off from the outside world, everyone becomes a suspect. Friendships begin to fracture, carefully constructed stories start to unravel, and every new piece of evidence reveals another layer of the truth.
Written by a real Police Detective, this stand-alone investigation combines authentic police procedure with an immersive mystery that unfolds one day at a time.
Synopsis
It’s December 2026, and the launch of a brand-new reality quiz show on Trezore Island should be a celebration of intelligence, fame and competition.
Instead, it becomes the scene of a murder investigation.
The contestants may have arrived to compete for quiz show glory, but behind the smiles and television cameras lie years of rivalry, jealousy and personal battles. Old scores have not been settled, friendships have broken down, and bruised egos are hiding dangerous secrets.
As detectives examine the evidence, you’ll follow the same trail of clues, uncover hidden secrets and question the stories of those left behind. With every contestant having something to hide, can you separate fact from fiction and identify the killer?
Your Investigation
Play solo, as a couple or with a group. Your case file contains 24 daily evidence releases, individually packed with witness statements, photographs, phone records, police reports, emails, interview transcripts and other realistic case documents. You’ll also find online footage which you will be guided to when required.
Open one evidence release each day as the investigation unfolds in real time, with new clues, leads and revelations bringing you closer to the truth. The final pieces of evidence arrive on Day 24, when you’ll have everything you need to identify the culprit and build your case. Once you’ve reached your conclusion, compare your reasoning with the official solution on our website.
To mark the completion of your investigation, Day 25 contains an exclusive Detective Pen, a final addition to your detective toolkit and a keepsake from the case. Whether you identify the culprit or not, you’ve earned your detective credentials.
Every contestant has a secret. Every clue matters. Can you solve the murder on Trezore Island?
Important Information
This investigation is designed to unfold in real time and cannot be started until December 1st 2026.
