In 1934, a friend brought fledgling actress Vivien Leigh to see Theatre Royal, where she would first lay eyes on Laurence Olivier.

Through previously unpublished correspondence and interviews with their friends and family, Stephen Galloway studies this tempestuous liaison, one that took place in the public eye as they struggled with love, loss, and mental illness.
