Cloruro de sodio

On her sixtieth birthday, a woman commits suicide. His death leads to the reopening of a cold case from 1988. To their astonishment, Carl Mørk and the team from Department Q discover that, for thirty years, a particularly cunning killer has chosen a victim on an appointed date, passing off the murder by accident or suicide. And he always leaves a little pile of salt at the crime scene. In the context of the sanitary restrictions due to covid-19, which make their work even more difficult, Department Q embarks on an investigation whose scope they cannot even imagine.
