Katka has nothing, she lost everything with her sister's death. Regina, on the other hand, has everything, but she still lacks something. Both want to punish the guilty. Katka comes up with a daring plan and infiltrates the family of two brothers, financial magnates from Brno, and turns their lives upside down. Regina refuses to give up and plays a game of cat and mouse. Both of them get into a carousel of intrigue and betrayal that can no longer be stopped. A raw detective novel set in the modern aristocracy, it paints a world where moral decay is wrapped in the tinsel of banknotes, and touches on the subject of drug dealing, prostitution and death. The murderous summer thus leaves behind the hundred times unanswered question of whether everything in the world can really be bought, and how cruel revenge can be, so that we do not become worse than the culprit himself.
