The one thing we know for sure is that the series only has two episodes left to go.
This brings it into line with previous series – there have always been six episodes in a series.
What’s going to happen tonight?
The official synopsis from ITV reads like this: “Cassie and Sunny interview two of the four suspects again and get closer to the truth about what happened the night Walsh disappeared.
“They learn that phone mast data puts Ram and Dean in the same vicinity three days after the announcement about Walsh’s body being discovered.
Cassie has a painful altercation with her father about his worsening dementia and later things take a devastating turn.
“Cassie has a painful altercation with her father about his worsening dementia and later things take a devastating turn.”
That means that as well as the investigation, there are a lot of personal storylines that take a dramatic turn.
What are the fan theories?
When it comes to the finale on Monday March 29, details are being kept very hush-hush.
There is only a little programme information available: “Despite a tragic turn of events, Sunny and the team narrow down the suspects.
“Will they find conclusive proof of who the murder weapon belonged to and succeed in bringing Walsh’s killer to justice?”
What we do know is that viewers have come up with their own fan theories about who committed the murder.
The leading theory at the moment is that Liz Baildon (Susan Lynch) and Fiona Grayson (Liz White) teamed up to stage the killing.
