Tell No One is a 2001 thriller novel by American writer Harlan Coben.

David and Elizabeth Beck, both 25 years old and married for less than a year, are celebrating the anniversary of their first kiss at a secluded lake when Elizabeth is abducted and later murdered.

Although the killer is found and prosecuted, David never gets over the tragic incident.

On the eighth anniversary of Elizabeth’s death, two long-dead bodies are unearthed at the same lake where the kidnapping occurred.

In addition, David receives a shocking email from an unidentified source that mentions a phrase only David and Elizabeth should know.

Tell No One was adapted for a French film in 2007, well received both critically and commercially.
