Sanna Tervo is Lauri Raiha's investigative partner in All the Sins, a detective who arrives in Varjakka as an outsider to the town's tight Laestadian community. Where Lauri carries the burden of personal history, Sanna brings distance and a willingness to ask direct questions, making her an essential counterpoint as the pair work the murder case at the heart of the first season.
Her outsider status is both an asset and a friction point: she is not bound by the loyalties and silences that complicate Lauri's relationships, but she must also navigate a community wary of strangers probing its affairs. The dynamic between the two detectives, balancing his insider knowledge against her detachment, drives much of the series' procedural tension.
Sanna returns in the third season, again partnering with Lauri to investigate the murder of a former constable and the search for a copycat killer. Her continued presence gives the series a stable professional relationship across its timelines and reinforces her role as one of the show's principal investigators.
