The Nobel's Will

In the sacred hall of Stockholm, where for a century ceremonies awarding the Nobel Prize have taken place, amid a large gathering of people, a hired killer—the elusive international criminal “Koshchka”—cold-bloodedly murders the chairwoman of the medicine commission. Annika Bengtzson, a journalist who has witnessed the drama, runs her own investigation in parallel with the official one.
The killer is known, but who is the customer? Annika tries to uncover the reasons for the drama in the scientific circles involved in nominating Nobel laureates. Soon she encounters several more murders, but fundamentally different ones—bloody and cruel. It seems another criminal is at work, and his actions are a terrifying revenge for past humiliations.
