Inspector Rebus writer Ian Rankin has written some of the best crime fiction of the past three decades.
The innovative format will combine real life investigative skills with expert knowledge to solve a fictional crime.
The winners must present their case to one of Scotland’s leading lawyers and convince them of their findings, in a bid to win £50,000.
So, what is the plot of the show and who are the teams of detectives? This is what you need to know.
What is Murder Island about?
According to ITV, the show is based on the fictional island of Hirsa, less than 20 miles off the west coast of Scotland.
The series was actually filmed on the remote Scottish island of Girgha.
When a body is discovered on the remote, tranquil island, a murder investigation gets underway.
The murder mystery has been written by Rankin, eight contestants working in groups of two will need to unpick the clues to determine the suspect, method and motive of the crime.
The investigation is overseen by some of the country’s finest real detectives, who will work
with the same information as the amateur detectives and will bring their own experience
to bear as they judge each team.
The teams have eight days to catch the killer, sifting through evidence, examining pathology and forensic reports and interviewing witnesses and suspects.
Once they have concluded their investigation, they must build a strong enough case to satisfy one of Scotland’s leading lawyers, then they could earn a £50,000 reward.
