Have the world-weary shamus and the former Aztec capital lost their noir juju?

The heroes are typically amateur or private detectives, possibly quirky, often women, sometimes a couple; they aren’t likely to suffer the afflictions common to the hard-boiled shamus — depression, rage, alcoholism, untreated trauma.

Philip Marlowe at quarterback, Easy Rawlins at strong safety, and a fierce defensive line of framed shamuses.
