The Sandhamn novels are set in the Stockholm archipelago, on the enchanting island of Sandhamn, known since the 17th century as the centre for the royal naval pilots.

Sandhamn is also the yachting centre of Sweden and home to the Swedish Royal Yachting Society (KSSS).

The island only has a tiny population of 120 islanders, but it is invaded by 3000 summer guests and hordes of tourists as well as sailing enthusiasts each summer.

The scenery is idyllic, but evil lurks beneath the surface.
