At the legendary Brenner Pass, in the middle of the Alpine idyll between South Tyrol and Austria, Commissario Grauner and his Neapolitan colleague Saltapepe must get to the bottom of a gruesome murder. An old man was tied to a horse and dragged to death. He led a withdrawn life, occasionally playing a game of cards with reticent friends from his youth. When it’s time to question them, one of them disappears without a trace. The investigation leads the Commissario to the darkest chapters in South Tyrol’s history. And an old suitcase holds clues to a possible connection between the case and a deadly tragedy that occurred years ago on Grauner’s parents’ farm – and for which, to this day, Grauner still doesn’t have an explanation. The silence of the night at the Brenner Pass – where statesmen, writers, merchants and globetrotters used to stop over in their travels – is deceptive.
