    Unsettling Beginnings

    In Sleeping Murder by Agatha Christie, we are introduced to Gwenda Reed, a young woman who has recently returned to England after living in New Zealand. She is looking for a house to buy and, by chance, comes across a beautiful Victorian house in Dillmouth. The moment she steps into the house, she is overwhelmed by a sense of familiarity and an inexplicable feeling of dread.

    Despite the unsettling feeling, Gwenda decides to buy the house and move in with her husband, Giles. As they start to settle in, Gwenda begins to experience vivid and disturbing visions of a woman being murdered in the house. She is convinced that these are not just nightmares but memories of a real event.

    Miss Marple's Intervention

    Disturbed by her experiences, Gwenda confides in her new friend, Miss Marple, a shrewd and observant elderly woman. Miss Marple listens to Gwenda's story and, despite the lack of concrete evidence, believes her. She suggests that Gwenda's visions might be connected to a real murder that took place in the house many years ago.

    Together, Gwenda and Miss Marple start to investigate the history of the house and its previous owners. They discover that the house was previously owned by a woman named Helen Halliday, who was murdered by her husband, Dr. Halliday. The couple had a maid, who was the only witness to the murder, but she disappeared soon after the crime.

    Unraveling the Past

    As Gwenda and Miss Marple delve deeper into the past, they uncover a web of lies, deceit, and hidden identities. They learn that the maid, who was believed to have disappeared, was actually sent away by Dr. Halliday to an asylum, where she died. They also discover that Gwenda herself was the little girl of the Hallidays, who witnessed the murder but repressed the memory due to the trauma.

    It becomes clear that Gwenda's visions were actually repressed memories resurfacing. The house, its rooms, and its surroundings were all triggers that brought back the traumatic event. Gwenda's husband, Giles, also plays a crucial role in helping her piece together the puzzle, despite his initial skepticism.

    The Final Revelation

    As the investigation progresses, Gwenda and Miss Marple realize that Dr. Halliday is still alive and living under a new identity. They track him down and confront him with their findings. Dr. Halliday, now known as Raymond West, confesses to the murder of his first wife but claims it was an accident. He also reveals that he had been planning to kill Gwenda, fearing that she might remember the past.

    In a dramatic turn of events, Raymond attempts to kill Gwenda, but Giles intervenes and saves her. The police arrive just in time to arrest Raymond, and Gwenda is finally able to put her past to rest. The house, which had been the source of her nightmares, is sold, and she and Giles move on with their lives.


    In conclusion, Sleeping Murder is a gripping tale of repressed memories, murder, and the power of the human mind. Agatha Christie masterfully weaves a complex plot, keeping the readers guessing until the very end. The book also showcases the enduring friendship between Gwenda and Miss Marple, who together solve the mystery and bring closure to a long-buried crime.
