The first terrorist attack in central Warsaw came without warning. The perpetrators announced the second and the third. They made no demands and gave no reason why they intend to strike twice more. They claim only that each attack will kill more people than the one before.
Leads are scarce and the authorities seem powerless. The whole city waits for the sentence to be carried out, while Wiktor Forst, held in prison, comes across a clue that might help prevent the tragedy. The case reaches the highest levels of power, so he enlists the help of people he can trust: Joanna Chyłka, Seweryn Zaorski and those they can vouch for.
THE FINAL CONFRONTATION BEGINS WITH AN EVIL THAT HAS NEVER BEEN SO DANGEROUS.
