BOOK IS IN POLISH - Every fame has its price ... The fact that in show business there is no room for weakness or scruples, Katie found out on the first day of the competition. America's greatest music show attracted crowds of applicants, offering instant success, international fame and, above all, huge amounts of money. However, no one is talking about the other side of the program.

Could there be anything worse than constant surveillance of private life, insidiously plotted plans or the boundless hostility of jurors? Of course ... the past!

BOOK IS IN POLISH - First week in the Criminal Investigation Department and her first case - man's dismembered body symmetrically arranged in plastic containers.

The task of the reader is to make choices at the end of each chapter to save the remaining victims and capture the murderer.

Can you save them all?

BOOK IS IN POLISH - And I vow to you love, fidelity and honesty in marriage ... What if your other half does something really bad? Something that is an extremely cruel act for you ... Will you stand for her in hard times, or will you hand her over to justice?

The book illustrates marital relations in the light of the law, pain and deeply hidden secrets.
