In the courtyard of the Pacific Heights building, a local waitress is found dead.

Five apartments overlook the murder scene. Five people witnessed a crime take place.

Finding the killer should be simple.

Except none of the witnesses' stories match.

They all saw something - from a different angle, at a different time.

None of them saw everything. Anyone could be the killer.

Detectives Carl "Bluey" Blueson and Lachlan Dyson, each with their own careers in peril, must solve what others assume is a straightforward case. But to unmask a killer they must unpick a complex puzzle - where the motivations of the witnesses are as mystifying as the crime itself.

How can you solve a crime if anyone could be lying?
