I was sceptical about how they were gonna make the show work for another season, but I'm pleasantly surprised and have this newfound excitement to continue watching! Who would want to kill Malcolm, why, and (how) do they know who Joe actually is? I love playing detective with shows like this, it feels really immersive, kind of interactive even.

For the people who haven't watched past S4EP1: Do you have any suspicions yet? My first hunch says Kate, given she gave in to Joe's strange request to not mention him to the police, her overall demeanour/personality, having a bad relationship with Malcolm and I could see her 'tricking' Malcom into recommending that flat to Joe.
