Inspector Wallander, the protagonist of Henning Mankell's "Faceless Killers," experiences a profound sense of curiosity and insight when he visits crime scenes. Each home he enters provides a glimpse into the lives of its inhabitants, much like the first impression one gets from a book's cover. This comparison illustrates Wallander's analytical nature as he seeks to uncover the hidden narratives and complexities of each case he encounters.

This metaphor highlights Wallander's role as a detective who not only solves crimes but also delves into the stories of individuals, revealing their fears, hopes, and connections. His investigations are propelled by an understanding that every home opens a chapter of personal history, inviting him to piece together the clues that are crucial for solving the mysteries within the novel.
