De Officier by Robert Harris

In fin-de-siècle France an army intelligence officer assigned to monitor the fallout from a famous treason conviction uncovers evidence suggesting the convicted man was innocent; as he quietly investigates, he confronts institutional antisemitism, forged documents and a determined military cover-up. Risking career and life, he navigates secret files, shadowy agents and political pressure to expose the real traitor and force a corrupt establishment to confront the truth in a tense, methodical historical thriller.
