"Episode 4" is the fourth episode of The Stranger. It was released on Netflix on January 30, 2020.

Synopsis
The boys make a discovery that sets Adam on Corinne's trail — and dredges up an old secret of his own. Kimberly gives Johanna a lead about Heidi.

Plot
The Stranger confronts Ed about his past affairs, telling him that he has a child he is unaware of. After he demands more proof than she provided him, she runs off. At Heidi's café, the police begin their investigation into her murder. Johanna asks Wes to hide the fact that she knew Heidi so that she can be assigned to the investigation. Adam confronts Mike's dad, Doug, after learning that the secretive phone call that Corinne made on the day of her disappearance was to him. Doug tells Adam that the phone call concerned the money stolen from the football club and that Corinne wanted more time to sort the situation out and to show her innocence. At the murder investigation, Katz attempts to throw suspicion on Heidi's husband or a burglar and volunteers to check the security videotape. Thomas and Ryan tell Adam that they have tracked Corinne's phone, and the three of them, with Killane, drive toward it, but eventually they find the phone abandoned on a bridge. Adam finally reports Corinne as a missing person to the police. Kimberley tells Johanna about the blackmail attempt on Heidi without disclosing the reason. Olivia, a schoolmate of Mike, Daisy and Thomas, collapses at a football game. We now learn that Katz is Olivia's father. He rushes to her side at the hospital. Wes and Johanna, unaware of Corinne's having gone missing, go to the Prices' house to speak with her, after evidence at the café indicates that Corinne had been at the scene of Heidi's murder.
