Why read this explainer

Compare the book's broader case construction with Doyle's concentrated pursuit. Incomplete closure belongs to the film's account of his obsession rather than a full reconstruction of the reported case.

PlotGeeks note

Street movement and surveillance give procedural obsession a physical form around Doyle. The incomplete closure leaves that pursuit distinct from the book's broader construction of the case.
