Lauren Braining, who set up a letting agency with Lucy before her death earlier this month, is set to come across an email from a mysterious client sent to her on the day of her friend's death.
"Her first thought is, 'It was meant for me. It was addressed to me, so why did Lucy go and meet them?'"
An email which requests a meeting.
Lauren immediately begins to wonder if Lucy - played by Hetti Bywater - met the client in her place, resulting in her death.
Actress Jacqueline Jossa said to Digital Spy: "She realises she might have found a crucial clue about Lucy's death.
"Her first thought is, 'It was meant for me. It was addressed to me, so why did Lucy go and meet them?'"
Lauren sets up a meeting with the client to confront them with her suspicions as she continues to struggle with Lucy's demise.
She added: "She feels like she owes it to Lucy to find out. No one else is trying to do anything about it. Lauren goes to the police, but they don't seem to take any notice and say they already know about it.
"But Lauren has an instinct feeling that it has got something to do with what happened - she might know the person and she might be able to help."
