Stricken with grief and refusing to believe her husband was having an affair, Ellie sets out to find the truth of who the mystery woman is, and why she was in the car.

Ellie goes to Milena's workplace using a fake name under the guise of being helpful – but really looking for clues as how Milena knew Greg.

But Ellie does not get the chance to find out the name of Frances’ lover.

After confessing her true identity to an angry Johnny, Ellie unsuccessfully tries to persuade a police inspector that Frances's and Greg's deaths were linked. Drunk and abusive, Frances's husband David turns up and admits to an affair with Milena to spite his wife's infidelity. Obtaining the truth behind the murders puts Ellie into danger.
