Simon Kemp notes that Japrisot's two most characteristic literary techniques are subjectivity and polyphony – "restricted first-person perspectives and a none-too-harmonious chorus of voices – which together produce the unreliable narratives by which his mysteries are sustained." His novels "are narrated or focalized through characters whose restricted perspective on the events they experience keeps the reader equally in the dark until the moment of revelation comes for both of them." Japrisot enhances this effect by occasionally using present-tense narration, "giving a sense of narration simultaneous with the actions recounted, and thus avoiding the artificiality of a retrospective narrator concealing his hindsight." The polyphony in Japrisot's fiction is used to balance "the restriction of viewpoint with a proliferation of different voices in telling of the tale." Those narratives are usually concerned with disputed events involving a number of witnesses and participants. "In the course of the narrative, the reader is then presented with various accounts of the same incident by different characters." As a result, "the truth is to be sifted by the reader from the variety of partial views and inconsistent testimonies offered."
