Murderous designs After the Wall, in the East, interference, love and crime

Eros and Thanatos: are they a filter for the epistemic distance of the detective in the crime novel, a filter for novels where the investigator is split into two (Rex Stout), a filter for police professionalism (procedurals). . .?
