The Nature of Evidence

Sir Clinton's investigation emphasizes the complexity of real-life evidence versus fictional detective stories, where clues are not neatly highlighted, and the detective must sift through irrelevant details to find the truth.

Key evidence is introduced: the scrap of paper in Neville's hand, the darts and tin box lid near Roger's body, and the sound of an airgun, all of which will be crucial to the investigation.

Sir Clinton uses photography, a dog's scent trail, and careful observation of marks and footprints to gather evidence.

Sir Clinton emphasizes exact times and reliable accounts, highlighting the challenge of piecing together conflicting memories.

The chapter focuses on the scientific identification of curare as the poison, highlighting the role of toxicological analysis in building a case.
