The production is narrated by Siobhan (Bridgette Amofah), Chris’s teacher, who guides us into her world through a book she has written about their chaotic, colourful and often unpredictable life. Along the way, the story tackles some surprisingly hard-hitting and mature themes, while inviting us to experience the world through the eyes of an autistic person. Chris is a character who is difficult not to warm to, with plenty of moments that generate genuine laughter. However, there were occasions when I found myself feeling slightly uneasy, questioning whether the audience was laughing alongside Chris or, unintentionally, at her.

Chris has a highly logical and mathematical way of thinking, coupled with a remarkable attention to detail. Everyday experiences that many of us take for granted—including unfamiliar people, crowded spaces, physical contact and unexpected changes to routine—can become overwhelming for her. She relies heavily on structure and predictability to make sense of the world around her.

At the same time, Chris is determined, intelligent and fiercely independent. Her fascination with detective stories inspires her to investigate the death of her neighbour’s dog, an investigation that gradually exposes difficult truths about her family. As the story unfolds, she is pushed far beyond the boundaries of her comfort zone, confronting situations that frighten and overwhelm her while taking significant steps towards independence.

Alex Keenan delivers a stellar performance as Chris, remaining on stage throughout the entirety of the two-hour-and-ten-minute production. There is an infectious sense of excitement and vulnerability within Keenan’s portrayal, complemented by a wide emotional range that makes Chris’s journey particularly mesmerising to watch. Keenan clearly understands the complexity of the character and brings considerable depth to Mark Haddon’s story, creating a performance that remains at the heart of the production.
