Stolen not only a wallet with a large amount of dollars, but also a portfolio with important documents, including a business plan of the company, representing a trade secret. When asked by Sasha, who suspects Shulgin, he replied that for several days at the night shop near the company sees the same company. Especially remembered him a bright young man with a scar on his face .. “It can’t be,” Sasha thought, “that such a coincidence!” Because it was this morning that she grabbed the thief’s hand with exactly the same signs . He pulled out her purse from the bag with all the cash.
