In the Scottish Highlands, along the secluded and rugged roads enveloped by mist, lies the picturesque town of Appin. Despite its scenic beauty, in the middle of the 18th century, it became the backdrop for a mysterious and unsolved crime that still echoes in the folklore of the region. The story is about the murder of Colin Roy Campbell, also known as The Red Fox, a hated government factor, who was assassinated in May 1752 on a lonely road near Ballachulish. The immediate suspicion fell on the Stewart of Appin clan, having had serious disputes with Campbell who was in charge of seizing their lands. The prime suspect was young Alan Breck Stewart. However, at the time of the murder, he was believed to be in France, which deepened the mystery. With no culprit at hand and under immense pressure to give justice, the authorities wrongfully convicted and executed James Stewart, known as James of the Glens, a quiet and respected leader of the Stewart clan. The horror of the unjust charge and execution stirred widespread public sympathy and resentment against the Crown. It also sparked an array of stories, songs, and legends about the doomed clan and their framed leader. The incident was famously fictionalized by Robert Louis Stevenson in his book, Kidnapped. Yet, the real killer’s identity has remained lost in the mists of time. The mysterious Appin murder is not only an unsolved crime but also a poignant folk tale that reflects the stresses and turmoil of Scottish history.
