Three-Act Tragedy

Anyone else a little let down by the reveal?

I just watched this one a few nights ago and very early on I suspected the actor/Poirot's friend was the killer and I was really hoping it wasn't that simple.

He seemed, to me, to be the most obvious suspect and it seems like there should be a rule in mystery stories that the most obvious suspect is never the killer!

All in all though still a pretty good episode.
