What happens
Inspector French travels to London to pursue three lines of inquiry: interviewing Mrs. Berlyn, consulting the Ardlo Magneto Company about the car's breakdown, and following up on earlier leads. He first visits Mrs. Berlyn, who expresses horror at the news of Pyke's murder but firmly defends her husband's innocence, though she admits her marriage was strained and that she had been close to Pyke. French then consults Mr. Illingworth, an electrical engineer, who explains that while a magneto can be deliberately damaged to cause a delayed breakdown, it cannot be made to fail instantly without leaving marks—contradicting the evidence that the car stopped at a critical moment. French is left grappling with this paradox.
Themes in this chapter
Deception and Secrecy
Mrs. Berlyn's guarded answers about her relationship with Pyke and the technical possibility of faking a breakdown highlight layers of concealment.
Coincidence vs. Design
The car's breakdown at a crucial moment seems deliberately caused, yet expert testimony suggests such a failure cannot be instantly faked—raising the question of accident versus intent.
Justice and Truth
French grapples with conflicting evidence and the difficulty of discerning the truth, especially regarding Berlyn's possible guilt.
