On the deceptively quiet island, where Agatha Sever, the author of popular detective novels, likes to draw inspiration, unexplained and disturbing events are happening once again. Several islanders contract a mysterious virus that claims the life of a Swedish tourist. Superstitious residents begin talking about an ancient pagan curse. The island’s history has seen similar cases, when the gods took revenge on people for desecrating their shrine. But the realistic Agatha does not believe in legends. Thanks to her experience and writer’s imagination, however, she has no doubt about the ingenuity of criminals.
