Tell No One is a French mystery/thriller from 2006. The film is directed by Guillaume Canet who also co-wrote the screenplay with Philippe Lefebre adapting the Harlan Coben novel of the same name. It has its moments of high excitement and danger, as well as times when it moves slowly. It plays like a Hitchcock film with the lead accused of a murder.
We hope that he is not responsible, we don’t think he is, but doubts begin to creep into our minds.
As the film begins a man and woman drive deep into the country to a rustic country house. Then later in the evening they go skinny dipping in a small lake.
The wife has to go back to the cabin to let the dog out. The husband, still on the raft, hears his name called out, shots fired, and then a scream. He dives off the raft, swims to the dock, climbs out, and is knocked unconscious by unknown parties. Flash forward 8 years and we learn that his wife was brutally murdered that night.
Who killed her is the main plot line that the rest of the film will be concerned with. Almost immediately following the wife’s murder, the police suspected the husband, the pediatrician Alexandre Beck. But they couldn’t make their case against him, so he was freed. We don’t see this as we have flashed forward the 8 years.
But in the present, two other bodies were discovered in the same area, so the police have decided to re-open the case of the murdered wife, Margot Beck. They ask for permission to search Beck’s property and for a DNA sample. He readily agrees.

But the complications from the earlier case keep simmering.
