generally the older crimes are still based on the attitude that the restoration of order was valued by the people.
Around the 50s the wealthy were seen to be immoral and corrupt, not the respectable aristocrates of christie's cosy crime. the police shift from not just being incompetant in relation to the detective ( scandel in bohemia etc) but corrupt as the criminals themselves. hence the lone detective hero... (phillip marlowe..)
from the 60s, you see that as society challanged authority and conventions that order and organisation was not valued, and random chance and chaos and cynicism took priority. this is exposed through parody real inspector hound etc.
the late 70s and 80s are particularily interesting with the rise in female detectives. putting a female in a traditional male role, gives women the strong, independant, uncompromising hero they desired.
90s has shifted focus to speciallty fields of criminal invetigation, paleontology (soz bad spelling), forensics etc. and once again back to the cops, criminal investigators, not the ammateurs.
