Called on a stormy night to the scene of his first murder investigation as the new commander of investigations, Inspector Avraham Avraham is shocked to discover that he knows the victim: Leah Yeger, a widow found brutally murdered in her home and the victim of a rape that he investigated some years beforehand. But with her rapist still behind bars, Avraham’s only lead is an eyewitness claiming he saw a policeman leave the scene of the crime—a policeman who seems to have vanished into thin air.

Jeopardizing the cooperation and loyalty of his police force, Avraham is determined to follow the lead, working feverishly to solve the case, no matter the cost. But when his investigation brings him to Mazal Bengtson—a young woman struggling to escape a tortured past and salvage a marriage gone horribly wrong—the complex case takes on an even more baffling, disturbing turn.

Told through the dual perspectives of Inspector Avraham and Mazal, The Man Who Wanted to Know Everything is a chilling investigation of secrets, family, and what happens when the people you love may not be who you think they are.
