Stefan Ahnhem - A halálos X

One early summer evening, a dinghy runs out of the harbor near Helsingborg, carrying a man with a sword crossed on his back. The cube made it clear what its mission was: someone had to die.
Detective Fabian Risk and his team have been working on quite a few murder cases in parallel in recent weeks and have solved several. But when they find another victim, they have to realize that they have been wrong all along. Fabian, who is bound at the same time by the recapture of his wife, the trial in which his son is also involved, and the investigation after one of his colleagues, realizes that this time they should not look for similarities between the deaths, but on the contrary: the differences.
But how do you catch someone who doesn't need a motive for murder? Someone who kills in a hundred different ways. Someone who plays a game that only he knows the rules of.
