the Scale？

Not enough context as the scale might be some name of a group or policy or whatever strictly isolated plot device with the book itself.

One theory could be: If one commits a violent crime (with a dagger or whatever), one must fear the consequences of the law. The scale could hypothetically be an abridged version of the scales of justice.


Derived from various mythologies: The scales are a device used by a mythological being, Justice, and are used to determine the guilt and value of a person who may or may not have committed a crime.
