In the gripping third episode of "The Woman in the Wall," titled "Knock, Knock," the small town of Kilkinure is still reeling from the loss of Clemence, Lorna's closest friend from their shared ordeal at the Magdalene Laundry. The episode delves into the psychological unraveling of Lorna Brady, as she grapples with sleeplessness, hallucinations, and the ever-encroaching suspicion of Detective Colman Akande.
The episode begins with a somber funeral for Clemence, a stark reminder of the tragic fate that befell the women who were mistreated at the convent. Lorna stands over the casket, lost in a memory of happier times with Clemence, before the harsh reality of the present intrudes. The funeral serves as a catalyst for the events that follow, as Lorna's mental state continues to deteriorate under the strain of her secrets and lack of sleep.
Detective Akande, now more convinced than ever that Lorna is involved in Aoife Cassidy's disappearance, attends the funeral with the intention of confronting her. However, Sergeant Aidan Massey advises him against doing so on the day of the funeral, suggesting a more delicate approach. This tension between the two officers reflects the broader conflict within the town—between those who want to uncover the truth and those who would prefer to keep the past buried.
Lorna's hallucinations escalate, and she begins to see and hear things that aren't there, including visions of Aoife Cassidy. This adds a layer of surrealism to the episode, blurring the lines between reality and Lorna's fractured mind. Her interactions at the wake with Clemence's brother, David, and later with Detective Akande, are fraught with tension and reveal the depth of her desperation to learn the fate of her child.
The revelation that David's sister had a daughter, Breda, and that Lorna might also have a chance of finding her own child, breathes new life into her search. The photo of Breda becomes a symbol of hope amidst the despair, driving Lorna to continue her pursuit of the truth despite the increasing danger and her own deteriorating mental state.
As the investigation continues, Lorna's actions become more erratic, culminating in a scene where she puts hot sauce in her eyes to stay awake during questioning by Detective Akande. This act of self-harm underscores her desperation and the lengths she is willing to go to avoid falling asleep and potentially revealing more secrets through her sleepwalking.
The episode also explores the dynamics between the characters, with Michael's protective instincts towards Lorna coming to the fore. His agreement to watch over her while she sleeps, and the subsequent scene where he awakens her from a dangerous trance, add a layer of complexity to their relationship and highlight the challenges of navigating a town where trust is a scarce commodity.
Detective Akande's own journey takes him down a path of discovery, as he uncovers connections between Aoife's disappearance, the Magdalene Laundry, and an organization called "The House of The Sacred Shepherd." His determination to solve the case is matched only by his growing empathy for Lorna, as he begins to understand the depth of her trauma.
The episode reaches a climax with Lorna's shocking revelation to Akande, where she confesses to killing Aoife and hiding her body in the walls of her house. The dramatic smashing of the wall and the subsequent discovery of nothing behind it serve as a metaphor for the fragility of Lorna's mental state and the town's collective memory.
"Knock Knock" is a masterful episode that ratchets up the tension and psychological intrigue. It delves deep into the characters' psyches, revealing their fears, hopes, and the lengths they will go to protect themselves and their secrets. The episode leaves viewers on the edge of their seats, eager to see how the pieces of this intricate puzzle will fall into place in the final episodes of the season.
