An unusual move, Tell No One is a French thriller adapted from an American novel by Harlan Coben (he's in the upper echelon of the beach-read authors). Winner of four categories at the 2007 César Awards, including Best Director, Tell No One explores the fall-out after a murder.
Alexandre Beck is a succesful doctor, but then his world is turned upside down by the brutal killing of his wife, Margot. He's trying to put his life back together when he receives an email from a woman claiming to be his wife.
So much for not telling anyone that you were dead, Margot.
