See How They Run

The ending of “See How They Run” reveals that the true culprit behind Kopernick’s and Mervyn’s murders is Dennis, the usher who had a deep personal connection to the story that inspired “The Mousetrap.” Dennis had lost his brother in a real tragedy and believed the play, which was based on his life, was exploitative and mocking his pain. His anger grew over the years as he watched the story being turned into a theatrical and cinematic spectacle, feeling that his grief was being profited from and trivialized. When Kopernick, the film director, began creating a climax that mirrored the original story of Dennis’ life but with added violence, Dennis saw it as a final insult and decided to take revenge. He murdered Kopernick and later Mervyn, who shared ideas with Kopernick and was involved in the film’s development.

However, the chaos reached its peak when Agatha Christie herself intervened. She cunningly offered Dennis poisoned tea, trying to calm him down and prevent further violence. Unfortunately, Dennis, in his desperation, seized Christie as a shield and almost caused more destruction. Stoppard and Stalker, the detectives, eventually uncover Dennis’ motive through clues he inadvertently left behind. They learn that Dennis felt betrayed and misunderstood, believing that the art based on his tragedy had been perverted to mock his suffering. Ultimately, Dennis’s rage culminated in a tragic shootout, where he held Christie hostage and was finally shot by Stoppard when he threatened to kill others, including himself. The film ends with Stoppard breaking the fourth wall, telling the audience not to reveal who the killer is, emphasizing the classic whodunit style.

In the final moments, Christie’s dinner at her house symbolizes that beneath the glamour and theatricality, real pain and unresolved trauma can still lie hidden. The story ultimately questions whether an artist’s creative liberties justify exploiting true human suffering, and whether society is willing to tolerate the uncomfortable truths that such stories may reveal. Dennis’s tragic story underscores the importance of respecting the line between art and reality, and how misusing personal tragedy can lead to devastating consequences. The ending leaves viewers pondering the blurred boundaries between fiction and life, morality, and the costs of artistic expression.
