Matt Rider, an English PI, is on holiday in Avignon with his girlfriend Zoé. They get talking to a local nurse in Avignon. She tells them that all is not well at the American clinic up on the hill. Matt thinks the nurse is crazy - until her husband calls with devastating news.

To investigate the clinic, Matt needs some bugs and a phone tap. But he doesn't know that the national security forces are involved, and he doesn't know that one of the surgeons will soon want Zoé dead.
