Sarah Pearse is an author best known for her debut novel, The Sanatorium. Born in the United Kingdom, Pearse grew up with an affinity for the English language, which led her to pursue a degree in English and Creative Writing at the University of Warwick. Her career began in Brand PR, working with various household brands, but her passion for writing endured.

After relocating to Switzerland in her twenties, Pearse was enchanted by the country's mountainous landscapes and the quaint Swiss Alpine town of Crans Montana, which ultimately provided the inspiration for her first novel. Her intrigue with the mysterious and the eerie, particularly remote and abandoned places, became a driving force in her creative process. Pearse's interest in the dark and creepy is evident in her work, which often explores these themes.

It was during her time in Switzerland that she came across an article about the history of sanatoriums in the area. This discovery lit the creative spark that led to The Sanatorium. Apart from her novel, Pearse's short fiction has appeared in various magazines, showcasing her versatility as a writer. She currently resides by the sea in South Devon with her husband and two daughters, where she continues to write and explore the depths of the thriller genre.
