A new biography, "Where Madness Lies," by Lyndsy Spence, delves into the life of two-time Oscar winner Vivien Leigh, exploring her mental health struggles and turbulent marriage to Laurence Olivier. The book draws upon Leigh's personal archives, letters, and audio recordings from those who knew her, painting a poignant picture of her descent into mental illness.

Spence aims to shed light on the often-misunderstood aspects of Leigh's life, focusing on her mental health journey and the harsh treatments of the time rather than sensationalizing her behavior. The book details Leigh's erratic postcards to Olivier while filming "Elephant Walk" in 1954, revealing her desperation for connection amidst her husband's infidelity with a mistress in Italy.

The book also explores Leigh's infatuation with Peter Finch, her co-star in "Elephant Walk" and Olivier's protégé, highlighting the complexities of their relationship and Finch's own personal struggles. Leigh's deteriorating mental state during filming led to a breakdown on a flight back to Hollywood, where she was ultimately replaced by Elizabeth Taylor in the film.

Upon her return to England, Leigh was committed to Netherne Asylum where she underwent harsh treatments including electroconvulsive therapy, ice baths, and forced comas. The book recounts Leigh's pleas to contact Olivier, who wrestled with guilt but ultimately felt distanced from the woman he once knew.

Olivier reflected on a disturbing incident during a 1937 production of "Hamlet" when Leigh exhibited frightening behavior, foreshadowing her later struggles. The book also touches on Leigh's early life, suggesting that signs of her mental health challenges were present from childhood.

Postpartum depression after the birth of her daughter, Suzanne, is also explored as a potential turning point in Leigh's mental health. Despite ongoing challenges, including miscarriages and erratic behavior, Leigh sought to understand her past in her final years. She found solace in religious texts and philosophies, ultimately finding peace before succumbing to tuberculosis in 1967.

Olivier, though remarried with children, mourned Leigh and acknowledged the profound impact of their love. Spence hopes the book will encourage open conversations about mental health, emphasizing the importance of support and understanding.
