In a hospital in Paris, a woman in her 60's has lost her memory. All she knows is that her name is Diana.

But she also knows secrets only Princess Diana could know. She wears a locket bearing pictures of William and Harry. And her best friend from boarding school has vouched for her: it's Duch.

Has the People's Princess really come back, or are thousands suffering from Diana Derangement Syndrome?

There's no doubt about this: In Paris, a tall, silver-haired lady with blue eyes, a shy, bemused smile, and a posh English accent, is beguiling crowds, raising consciousness, and giving King Charles a right royal headache.

In a hilarious, fast-paced chronicle of three eventful weeks in Paris and London, JB Miller weaves a heartfelt social satire of royals at war.

"Duch has pathos, joy and humor... It takes a masterful writer to create this complex and beautiful dream, and Miller is a master!"

"Duch works on so many levels: farce, satire, page-turner, reportage, cultural commentary, counterfactual history, punch line. It rings true with all its implausible narratives and has a surprising affection and respect for the royals, for each of their private and royal selves."
