Katka has nothing, the death of the sister lost everything. Regina, on the other hand, has everything, but she still misses something. Both want to punish the culprits. Katka devises a bold plan and infiltrates into the family of two brothers, Brno financial tycoon, to whom he will overturn his life inside out. Regina refuses to give up and plays the game on the cat and the mouse. Both of them get into the carousel of intrigue and betrayal, which can no longer stop. A raw detective novel from the environment of a modern nobility draws a world where morale is packed into a tinsel from banknotes, and touches on drug trade, prostitution and death. The murderous summer leaves behind the hundred times the unanswered question whether everything in the world can actually be bought, and how cruel can be revenge, not to become worse than the culprit.
