Murder Island Episode Rating Graph

The body of Charly Hendricks has been discovered and the murder investigation begins. This is no ordinary murder mystery, but one set by crime writer Ian Rankin for eight ordinary members of the public to solve and win the £50,000 reward.

After 24 hours on the case, the rookie detectives have competing theories about who killed Charly, but nothing's been proven. By the end of the day, two of them will leave Murder Island.

A mysterious dinghy washes up on the beach as the teams are informed the island is a known drug smuggling route. It could be another motive for murder and may explain the appearance of the threatening Freddie Forrester.

The detectives are under huge pressure to nab Charly's killer. Was it Hamish in a jealous rage? Or is land agent Alicia not so sweet and innocent after all? The net begins to tighten.

The two remaining teams focus down on their suspects, but as they close in on the truth, the race is on to find a vital piece of evidence that could reveal the motive for Charly Hendricks' murder.

The final two rookie detectives are closing in on Charly Hendricks' killer. If they can they get a confession or find hard evidence of the murder's identity, they'll walk away with the £50,000 reward.
