Natalya Alexandrova, known for her gripping novels in the “Artifact&Detective” series, presents a new detective story titled “The Deadly Tool of the Aztecs.” At the center of the plot is a mysterious musical instrument of the ancient Aztecs, which could kill and maim with its sound—and control people as well. In modern times, police officer Petya Lebedkin and his partner Dousya come across this artifact. They investigate a puzzling case where the fates of four unknown girls intertwine—three of whom have already died. The dead were found with expressions of terror on their faces and damaged eardrums.
