Who walks in the mists of Edinburgh?

The young Robert Louis Stevenson, recently returned from Europe, meets two red-haired twins: Jackie and Hydie. They are the daughters of a pragmatic police inspector doomed to investigate cases linked to the occult. The trio, with Jackie’s initiative, Hydie’s sixth sense and Louis's curiosity, will become the invisible hands guiding the inspector in solving his cases. With a passion for mysteries, and flair for the supernatural, they alone can read the subtle magical trail hidden behind apparently simple cases.

• Jackie and Hydie are inspired by Jekyll and Hyde. They are identical twins with opposite personalities.

• A young Robert Louis Stevenson plays detective hunting down monsters and stories.

• The mysteries of the creatures from Scottish folklore, the dark alleys of Edinburgh, and the foggy moors, explored by three young detectives.

The Swan Mask

One morning, at dawn, Louis is wandering in the autumn mist near Edinburgh - city of woods, witches and spirits - with his writer's notebook. He’s only fourteen years old but already nurtures a passion for adventure. Suddenly, he hears a hiss and sees a dagger sticking into the tree trunk next to him. This is how he meets two enterprising and fascinating twins: Jackie, with a confident air and clear beauty, and Haide, more silent and elusive. The two sisters turn to Stevenson: "Someone's going to die, and we've got to stop it. Are you with us?" And so begins an adventure in search of mysteries, crimes and culprits.

The Sea Curse

A macabre affair disrupts Edinburgh: an endless storm has raged in port for three days, preventing the ships from leaving. Since the storm began to rage, three sailors have been found dead in their houses, murdered in a horrific way: the soles of their feet have been peeled. When Lewis, Jackie and Hydie come across, by chance, a sailor who seems to know something more, and then meets the same fate, they decide to investigate.
