X: Discordant Notes explained

The Burtell case continues to generate public sensation and amateur detective activity.

What happens

The Burtell case continues to generate public sensation and amateur detective activity. Inspector Leyland reports his investigation findings, which include a suspiciously perfect alibi for Nigel. Meanwhile, Mr. Erasmus Quirk, an American detective club member, arrives at the Gudgeon and insinuates himself into the Bredons' company, prompting Angela to offer misleading half-truths about her husband's involvement. Leyland and Bredon discuss the evidence, including the lock-keeper's testimony and the stranger's polite gesture.

Key passages

  • Nothing stimulates the public imagination so powerfully as the existence of an official theory; its merits and demerits were hotly debated in clubs and railway-carriages; bets were freely exchanged, hairdressers became intolerable on the subject, and even dentists would gag you and then let you have the benefit of their opinions on it.

    The official theory captivates the public, sparking debates everywhere from clubs to trains, with people betting on it and even professionals like hairdressers and dentists offering unsolicited opinions.

    Highlights the public's obsession with the case and the pervasive influence of the official theory.

  • Yes, only (as I say) it's just a bit too perfect. The young man seems to have been at such elaborate pains to leave memories of himself wherever he went. There's not a link missing in the chain, you see; it looks as if he'd definitely meant to establish his whereabouts at every moment of the day.

    Bredon notes that Nigel's alibi is suspiciously flawless, as if he deliberately ensured every moment of his day was witnessed.

    Reveals Bredon's skepticism about the alibi's authenticity.

  • She fell back, therefore⁠—I am afraid it was her custom⁠—on a misleading series of half-truths; her husband had been remotely acquainted with the young man who had disappeared, and certain business friends had urged him, since he was at leisure, to apply what diligence he could to the solution of the mystery.

    Angela, as usual, resorts to half-truths, claiming her husband knew the missing man and was asked by business associates to help solve the case.

    Illustrates Angela's tendency to deceive with partial truths.
