The Island (season 1)

Crichton is a young Family Liaison Officer charged with investigating a brutal murder at a remote island mansion committed by the wife of a local tycoon. Several years ago, Kat disappeared from the island of Lewis and Harris, where the murder investigation unfolds. Among the key witnesses is the mansion's long-time housekeeper, Mrs. McGregor, who claims to have seen shadows moving in the garden on the night of the murder. Another suspect is the tycoon's estranged brother, Alan, who had a heated argument with the victim just days before the incident. Additionally, the gardener, a reclusive man named Ewan, is known for his mysterious connection to Kat's disappearance years ago.rn
