Throughout the series, London detective Marcella has been investigating a series of child murders, and in episode seven, she was led to the house of Nigel Stafford, who held her at knifepoint before revealing that his girlfriend Rosio was being kept captive by the murderer. This gave Marcella and her colleagues a direct line to the murderer who had been in contact with Nigel online. But an attempt to track him down led to Rosio’s death.
Elsewhere, Marcella’s son Edward popped round to visit his ex-girlfriend Samantha, only to be invited inside and poisoned by her mother Jane, who apparently suspected Edward of beating her daughter.
Many viewers took to Twitter to theorise as to what might be going on. Is Jane the killer? Is there a group of murderers? Why are Marcella’s trousers so short? Users shared some elaborate answers on Twitter.

Totally forgot that samantha's mum's sister runs the care home. And she was part of the band and the missing girl. She has linked to every single part of the investigation and we have never even suspected her. Brilliant #Marcella
There are four of those symbols that get put into every child’s body. The vet woman has one of the symbols on her arm. Which theoretically would mean there is another THREE woman with the other symbols tattooed somewhere on them. A cult with different agenda’s. #Marcella
After Samantha got abused at 14, she became a prostitute who met two others abroad…who then came up with this "women ring" to stop future abusers. I'm going with 3 of them – Samantha's mum, Becky and one of the lesbian couple – they use Maya for her connections #Marcella
