Airside by Christopher Priest
Hollywood actress Jeanette Marchand was beautiful, talented, beloved by audiences.
During a time of personal crisis, she declares she is going to take a vacation in England, to explore the possibilities of working in London, before returning to the USA.
She never returned to the USA. She never even left the airport. At least - no-one saw her leave.
Years later, a young film student finds himself digging deeper into her disappearance. Where did she go? Was she really dead? Who was the mysterious man who sat beside her on the flight across from New York?
This is a gripping speculative historical novel, grounded in the golden age of film. Perfect for fans of true crime, conspiracy theories, and SF that is chillingly close to reality.
