The Housemaid's Secret

Wendy tries to remember if the window was open when they arrived but can’t. She closes it because the rain is coming in. She takes the wine to the bathroom and finds Russell crying. She tells him to stop and pours them both a glass of wine. Russell downs his quickly, so Wendy follows suit.

Wendy is content after two glasses of wine. Her phone rings, and she’s expecting a call from Joe Bendeck. She climbs out of the tub and goes to answer the phone. It is Joe, but when Wendy asks when he will transfer control of Douglas’s estate to her, Joe informs Wendy that Douglas changed his will so that all the money goes to charity. Joe tells Wendy she needs to move all her things out of both the penthouse and the Long Island home so that they can be sold. Wendy hangs up on Joe determined to fight the will.

The phone rings again and this time it is Ramirez on the other end. She expects that he is calling to tell her Millie has been arrested, but Ramirez says Millie hasn’t been located yet. Instead, Ramirez has called to ask about a security camera that was just found on the back door of the building where Douglas’s penthouse is located. It turns out the camera was paid for by Douglas and positioned so it would not be visible to residents. The video from this camera shows that on the night of the murder, Douglas didn’t arrive at the penthouse until after Millie left. Wendy hangs up on Ramirez and rushes to the bathroom to talk to Russell. When she enters the room, she sees that Russell’s throat has been cut.

The lights go out. Wendy assumes Millie is Russell’s killer. She retreats to the kitchen, hoping to get a knife from the counter to defend herself. Wendy calls out to Millie, claiming everything she told her about Douglas’s abuse was true. Wendy enters the kitchen and slips on something wet on the floor, assuming it is blood from Millie’s footprints. She continues to call to Millie as she crawls to the counter and searches for a knife, but the knives are gone. She hears footsteps enter the kitchen.

Wendy continues to search for a weapon as she speaks, offering to pay Millie off and to go to the police to clear things up. However, in a flash of lightning, Wendy sees the person standing over her and it isn’t Millie.

Marybeth stands over Wendy with a knife in her hand. She orders Wendy to sit at the table and sits across from her. Marybeth wants to know how long Wendy and Russell were having an affair. Wendy admits to being with Russell for 10 months. Wendy also admits to killing Douglas when Marybeth pushes her. Marybeth gives Wendy a piece of paper and pen, telling her to write a confession. Wendy writes about the affair and her decision to kill Douglas. Marybeth tells her to include a line confessing to Russell’s death and her own death by suicide. Wendy does, then signs the paper.

Wendy begs Marybeth not to kill her, admitting mistakes, but saying it will be worse for her to have to live with her mistakes. Marybeth doesn’t agree. Wendy tells Marybeth that she can’t use the knife because people don’t usually die by suicide that way. Marybeth agrees. Marybeth explains that there was digoxin in the wine and that it will cause a fatal arrhythmia. Wendy continues to beg for her life, but Marybeth is content to watch her die slowly and painfully.

Millie wakes in the back seat of Enzo’s car and decides it is time to go home. When she arrives, there is a police car waiting for her. On the way to the station, Millie turns on her phone and discovers dozens of calls and texts from Enzo. She texts him, letting him know she is safe and on her way to the police station. He informs her that Wendy Garrick is dead.

Ramirez meets Millie in an interrogation room and tells her Wendy confessed to Douglas’s murder in her note. He also says there was a camera on the back door of the apartment building proving Millie’s story. Ramirez then tells Millie the main reason he asked her back to the police station is that he’s heard about her reputation, and he wants to give her his card so that she can call him if she ever needs help while rescuing another survivor of abuse from their abuser.

Three months later, Enzo is moving into Millie’s apartment. Enzo used his charm to convince the landlady to allow Millie to stay, and now he is filling the apartment with so many boxes, Millie isn’t sure what they’re going to do with it all. As Millie waits for Enzo to bring the last load, Brock knocks on the door. She gives him a small box filled with clothing and other items he left at her apartment. Brock asks if Millie found the bottle of digoxin he kept in her medicine cabinet. She tells him she must have thrown it away. However, the truth is that Millie visited Marybeth and told her about Russell and Wendy’s affair. Millie gave Marybeth the digoxin, explained how it worked, and what an overdose would do. Millie reflects on the fact that both Douglas and Brock took the pills, and how easy it would have been for Wendy to slip an overdose to Douglas, and no one would have been any wiser.
