The Grave in the Dunes (Case for the Master Sleuths‪)‬

GET AWAY WITH MURDER? NOT ON OUR WATCH!

In the untamed dunes of the North Sea island of Sylt, sled dog Athos cherishes his wild escapades—particularly as winter's chill approaches and the ebbing tourist influx grants him the freedom to explore undisturbed. However, one fateful night the sands reveal a chilling secret: a freshly dug grave.

Beneath the disturbed earth lies a man who has met a brutal end. As the police delve into the mystery, they discover he was a private investigator commissioned by a renowned film star.

Has the tranquil haven of Sylt been tainted by the presence of a cunning killer? And if so, who else might be ensnared in their deadly trap?
