The Chestnut Man
Copenhagen trembles before the actions of a psychopath.
His calling card is the chestnut man, a figure made of chestnuts and matches, which he always leaves at the scene of the next bloody crime.
Upon examining these figures, criminologists came to a shocking conclusion: the chestnut men bore the fingerprints of the small daughter of a well-known female politician. But the girl disappeared and was presumed murdered a year ago, and the person who confessed to this crime is already in prison… Is this a coincidence or some devious and horrific calculation? This must be determined by two Copenhagen detectives. And they must find out quickly, as everyone knows: the unknown maniac has only just begun. And has no intention of stopping…
Plague Island
Gothenburg, 1925. The body of a well-dressed man is pulled from the murky waters of the Saveon River. A thin but deep bloody wound, gaping under the silk scarf around his neck, leaves no doubt: the man was strangled. Strangled in a very cruel and exotic way – with a garrote, a Spanish execution device that tightens around the neck with a thin iron wire…
Several years ago, a whole series of similar murders occurred in Sweden. At that time, the criminal was caught, declared insane, and is now the only inmate on a remote island dubbed Plague Island. By the way, it is on that very island where the strangled man was born and grew up… Recently, a famous Swedish writer detailed precisely such a murder in his novel. And he is also mentally unwell and is under round-the-clock observation… on Plague Island. Could it be that the imprisoned criminal and the trendy writer are the same person? Senior Constable Nils Gunnarsson sails to the island – and finds the mad inmate where he belongs: in an isolated cell under seven locks…
