Trial and Retribution - explain ending?

[black bunny]

can someone please explain the ending of this, I'm confused. I understood that the boyfriend did the murder, and the sister of the murdered girl was found not guilty of murdering the foreign bloke,but - what else? Who was "Margaret"? Was the sister involved in the murder?

Someone please explain it so I can understand.!

The sister who murdered the man was Margaret and had been pimping her sister and other Eastern European girls.

This was discovered by the bank statement showing she had nearly �800000 , and her answering her mobile and saying 'Yes, this is Margaret'
