The first part of the captivating Finnish bestselling crime series

The summer solstice is approaching, and a blue shipping container appears in front of the gates of the villa of a large business family famous for their charity. Although it belongs to the Lehmusoj concern, no one knows who had it brought there. For an equally inexplicable reason, the container is full of water and a drowned dark-skinned woman is floating inside like a huge tin aquarium. Commissioner Paula Pihlajová begins to investigate the strange crime, and the traces lead her all the way to Africa, where the founder of the concern Hannes once ran a business and became startlingly rich thanks to development aid.

At the same time, the life of the commissioner herself is shaken to its foundations, because a 20-year-old drug addict, with whom she has a painful relationship, has just been convicted of murder. Paula suffers from feelings of guilt and tries to get to the bottom of how the young man went astray. In the meantime, in the investigation, all clues point to the Lehmusoy family, but at the same time, a deadly noose tightens around them.
