Psychology of Crime

How The Canary Murder Case develops Psychology of Crime.

Vance uses psychological analysis and aesthetic principles to deduce the murderer's character, arguing that the crime's technical perfection reveals a calculating, superior intellect rather than a common criminal, and that the killer is a 'logical, calculating madman' driven by desperation.
