Why read this explainer

Compare the falcon pursuit and Spade's final choice with the fuller hardboiled texture. Dialogue and performance give the retained decision a tighter screen presentation.

PlotGeeks note

Timing, posture, and dialogue express the code driving Spade's difficult choice. Tightening the pursuit changes its presentation without removing the moral pressure of that final decision.
