This is what happens when you put a pair of unemployed teenagers in charge of a sudden death investigation. What we lack in investigative skills we make up for in free time.

Heidi's meant to be having the time of her life on exchange in Switzerland, but instead she's cold, all alone and on an involuntary dairy-free diet. So when she hears the news of her brother Felix's death, she readily jumps on the first plane home to Perth.

To be completely honest, Felix wasn't that much of a brother, so Heidi's not crying buckets - but she's not exactly happy either. Thanks to an epic betrayal by her (ex) best friend and (ex) boyfriend, Heidi has absolutely nothing to do and no one to talk to. That's until Patrick, the wisecracking younger brother of Felix's widow, convinces her that they need to investigate her brother's mysterious death.

Will Heidi and Patrick get to the bottom of Felix's death - and do they really want to?
