Silence by Jan Costin Wagner

When a teenage girl named Sinikka goes missing in the same place that another girl disappeared and was found murdered thirty-three earlier, the authorities, especially recently retired police detective Ketola, believe the cases are connected. The death of Pia Lehtinen always weighed on Ketola's mind and he uncovers from the police department's basement the model he created of Pia's murder scene. He gives all this old material to his colleague, Kimmo Joentaa, who is in charge of the new case. Joentaa speaks to both Pia's and Sinikka's families, trying to find some connection between the girls. While Joentaa's investigation moves forward, real estate agent Timo Korvensuo slowly becomes unsettled when he hears of Sinikka's disappearance. It turns out he knows who killed Pia... Silence is the third book in the Kimmo Joentaa series and is most similar to the mysteries of Karin Fossum.
