In literature, "sangfroid" is deployed to characterize a demeanor of unwavering calmness and self-possession, often in the face of danger or absurdity. Authors ascribe this quality to characters who remain impressively composed, whether in dramatic circumstances or mundane tasks. For instance, one narrator admires a group’s composed courage in adversity [1] while another casually describes a character pocketing his handkerchief with notable nonchalance [2]. In more sophisticated portrayals, a character's ability to maintain calm while issuing orders under pressure adds an element of understated heroism or irony [3]. Thus, "sangfroid" serves in literature both as an ideal of fortitude and as a subtle commentary on the nature of cool detachment.
