The Mystery of Orcival · Chapter
The Logic of Guilt explained
M.
What happens
M. Lecoq presents a detailed logical argument to M. Plantat and Dr. Gendron, building a case that Count Hector de Trémorel is the likely murderer. He reconstructs the crime scene, analyzes the search for a hidden letter, and explains how the count's actions—including the display of banknotes and the framing of Guespin—point to his guilt. The chapter ends with a moment of tension as Dr. Gendron thinks he hears someone in the garden.

Key passages
“The inquest of a crime is nothing more nor less than the solution of a problem. Given the crime, proved, patent, you commence by seeking out all the circumstances, whether serious or superficial; the details and the particulars.”
Lecoq explains that solving a crime is like solving a problem: start with the known facts and then find the person whose guilt explains every detail.
Lecoq outlines his detective methodology.
“He throws the hatchet down violently—it cuts the floor. He rushes down, slips the banknotes in his pocket, seizes Guespin’s torn and smeared vest, which he will throw into the river from the bridge, and saves himself by the garden.”
Lecoq describes how the count, upon hearing the discovery of the body, panics, grabs the incriminating vest, and flees through the garden.
