The head of an advertising company, Vadim Shulgin, contacts private detective Alexandra Danich: in the morning, on his way to work, he was robbed in a dark, deserted arch. Not only was a wallet with a large sum of dollars stolen, but also a briefcase with important documents, including a business plan for the company, which is a trade secret. When Sasha asked who Shulgin suspected, he replied that he had been seeing the same company at the convenience store next to the company for several days. He especially remembered a fair young man with a scar on his face. “It can’t be,” Sasha thought, “such a coincidence!” Because just this morning she grabbed the hand of a thief with exactly the same signs. He pulled out her wallet with all the cash from her bag.
