Solstice

On the morning after Solstice night, student Bennie Lindner is found dead below a rocky plateau. When the detectives pick up a fugitive at the green border to Austria who is in possession of Bennie's backpack, the case seems to be solved. But then Beissl's daughter Eva discovers videos on the internet of reckless challenges, with which Bennie and his two climbing friends Sebi and Lena were engaged in a real competition. Was one of these challenges Bennie's deadly fate?
And what role do the victim's mother, Wally Lindner, and Lena's father, the obscure mountaineer Hans Staudinger, play? Both seem to be hiding something from the detectives.  In the end, both questions actually lead to the solution of the case, but quite differently than Beissl and Jerry initially suspect.
