Was it just me spoilers

I thought the Husband was the killer until Cam became painfully obvious after episode 3 maybe. Can't remember whether it was 3/4.

Firstly, the killings only started when she returned, I found it weird (although now knowing it is Cam not so much now) that the killer already knew about her arival. But obviously Cam was a cop so word about her arival would have been spread through the police force.

I thought that the Husband had a possible connection to the previous killer of Sarah's parents.

I then thought maybe he wanted to set up his own killings and eventually capture the killer (As in frame someone), because he was a journalist he would end up rich and famous. That is a really simple explanation by the way I am too tired right now to go into detail.

It has been a while since I watched the show. So these are the only details I can really give from memory.

But I always thought it was the husband until like episode 3/4. This was also the case because I was told that the killer was painfully obvious and so when I went into viewing, I just presumed his suspicious behaviour in the first like episode or 2 literally highlighted him being the actual killer.
