Rekke and Vargas have earned a reputation for solving the unsolvable. But they’ve never been confronted by a serial killer. Until now. Rekke receives a visit from Spanish inspector, who is unable to forget the brutal, unsolved murder of a young woman in Santander in 1988. Now other bodies have come to light, marked with signs that seem to be some kind of numerical order. Still recovering from his latest manic episode, Rekke agrees to help decipher these signs before the killer strikes again. The victim was an aspiring writer and clues from her posthumously published short story draw Rekke and Vargas deep into the murk of Sweden’s literary scene. To unmask the killer, Rekke must relearn the difference between fact and fiction, and discover what really happened that night back in the 1980s.
