  • The Primacy of Rational Deduction

    The opening quote underscores the necessity of thorough, rational investigation, comparing the detective's work to the persistent fool-bird.

Key passages

  • The policeman must oft follow the precept of the ‘bakadori’—those fool-birds who, though they know disaster awaits them at the hands and clubs of the beachcombers, brave ignominious death to bury their eggs in the sandy shore. … So the policeman. All Nippon should not deter him from hatching the egg of thoroughness.

    A policeman must be like the fool-bird that persists in burying its eggs despite knowing the danger, because thoroughness is essential regardless of obstacles.

    This metaphor establishes the theme of relentless dedication to investigation.
