Emmerdale aired a bombshell on Thursday night, as the exact details of Andrea Tate's post-mortem were confirmed.
Her former mother-in-law Kim Tate was arrested on suspicion of murder, and grilled over her final showdown with Andrea a day before her death.
Andrea's dead body was found in the burning maze at the survival challenge event, with only one person knowing she was in there - her killer Meena Jutla.
It was believed she had tragically died when the maze was accidentally set on fire, with an investigation into what caused the fire ongoing.
But a report conducted by the Fire Officer combined with the results of the post-mortem led to a damning claim, with Kim in the frame.
It's believed by those investigating the death and the incident that the fire in the maze was a cover-up, to conceal the murder of Andrea.
They revealed that the fire itself did not kill Andrea, and that she sustained a fatal blow to the head.
The detective told Kim that the line of inquiry they are following is that someone hit Andrea over the head and killed her, before starting the blaze to cover up their crime - or at least make it look like she accidentally died in the fire.
Of course viewers know that Meena murdered Andrea, after she saw her trying to drown Victoria Sugden in the river.
She chased Andrea around the maze before slamming her head on a wooden post, and leaving her for dead.
The maze was on fire at this point, because Andrea accidentally fired a flare gun at the maize after a struggle with Meena.
Meena then attacked Andrea - and it seems this attack is what eventually killed her, and not the fire.
It had been a little unclear whether Meena was technically a killer or not, given Andrea regained consciousness twice and did try to escape - even grabbing the walkie talkie to try and alert the team she was in danger.
But despite this, she eventually died with many no doubt assuming it was the smoke inhalation or the fire that actually killed her.
Meena did murder Andrea though, with the fatal blow to the head, so perhaps if she had survived the fire Andrea would have sadly died anyway.
The detective might be wrong in believing the fire was started after the murder as a cover-up, but he did reveal a flare gun found at the scene was being tested for prints.
It will bring up Andrea's DNA given she was holding it, and Meena wiped it before placing it back in Andrea's hand - but perhaps this will lead to the conclusion the fire may have been accidental, as Andrea tried to get help.
Either way, the cause of death will no doubt lead to more questions meaning Meena might want to watch her back.
Emmerdale airs weeknights at 7pm on ITV, with an extra episode at 8pm on Thursdays.
