Without You - Season 1 Episode 2

Ellie goes to Milena's workplace using a fake name and offers to help sort through Milena's paperwork on the pretence of being helpful - but really looks for clues as how Milena knew Greg. Milena's business partner Frances Shaw confides in Ellie that her own marriage is over as she had fallen for Milena's lover. When Ellie asks Frances who her lover was, they are interrupted but agree to meet later at the office to talk. However, when Ellie returns, she realises that she is too late.
