What could have been huh? There's no telling though because absolutely nothing happened in the two episodes. It took an episode and a half for the contents of the synopsis to take place, leaving no room for anything else to happen.

What followed was a whole lot of flashbacks, which would've been understandable if this was a long format series with a lot of twists and turns and actual intrigue and suspense about who the murderer is. Unfortunately, since everything is incredibly obvious, the flashbacks play no role. It would have at least made sense if they were just showed once, but one scene was shown as a flashback multiple times, and this applied for several scenes.

It's a shame though, because there was absolutely no story beyond the synopsis, no proper genre you could think it is, and not even a proper conclusion to what could have been a solid miniseries.
