One night, Mitya Khokhlov lost an old friend Kuzya and… one hundred thousand dollars. That’s what coincidences are like. Or not?
Once upon a time there were four friends: they studied at the same university, worked at the same research institute at first. But later two of them became businessmen. And Kuzmin and Pilyugin stayed in science. Kuzya was a clumsy, forever dissatisfied failure who once had big hopes. True, lately he insisted that he would soon get rich—and even made a marriage proposal to their common friend Arina. And then they killed him… in the yard of Pilyugin’s house. If he died because of money, where did a simple scientist get it from—and who could know about it? Only someone close… Mitya Khokhlov urgently needs to find out who the killer is and who the thief is.
