An unprecedented thing - Major Voronkov, an old friend and at the same time an opponent of the amateur detectives Marina and Alina - he turned to them for help: he asked them to go to the theater and get acquainted with the actress Elizaveta Vetrova. Elizaveta's sister was killed, and it seems to Voronkov that the actress does not say much... Pretending to be journalists, the ladies agreed to meet with Lisa after the performance, but found her strangled in the dressing room! Voronkov immediately tried to remove them from the case, but it was not there. Marina and Alina found a strange note at the crime scene "Baby, I've been looking for you the longest" and they intend to find out for themselves what it means!
