1. Death on Thursdays

An attempt was made on businessman Marat Shaikenov. Shaikenov believes that this is the same sniper who has been keeping the entire city in fear for a month, committing more and more murders. Shaikenov turns to the Beagle detective agency with a request to find the sniper. Moreover, death now threatens not only him, but also his fiancée Ella. Investigating this complicated case, private detective Andrei Rostovtsev meets family psychologist Alina Belova, who, thanks to her professional experience, helps Rostovtsev identify the criminal. Rostovtsev invites Alina to become a member of his team.
