Archbishop Valdieri from New York is impatient to get the Pope to the Clinic of the Little Sisters of Tourvillon in Avignon, France, for treatment. The surgeons at the American-owned clinic are eager to treat the Pope, but the Archbishop suspects there's a problem. 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. Shroud of the Healer is the second Matt Rider detective thriller.
