The Mystery of Orcival · Character

M. Lecoq

A detective who treats a country murder like a chess problem, reading silences and slips of the tongue as clues while everyone else sees only a respectable marriage.

Also known as Lecoq, Monsieur Lecoq

First appearance: ii

As a major figure in The Mystery of Orcival, M. Lecoq is not background color—the story leans on what they do once the chapter opens.

The detective arrives incognito, having already gathered intelligence by mingling with the locals, and impresses Plantat while irritating Domini.

Lecoq arrives at Orcival to untangle a killing that the neighborhood insists could never have happened, and he quickly discovers that the real puzzle is not the corpse but the decade of hidden hatred behind it. He works by provocation as much as deduction, letting witnesses like Plantat talk until their own corrections betray them. His suspicion that the truth turns on whether certain proofs still exist makes him the engine of the investigation's middle stretch.
