The Secret That Brings Death

In a small village at the edge of a cliff near an overgrown pond, the body of a beautiful young woman has been found. That night, Maria, happy and dressed up, was hurrying to a date with her fiancé, but... she never arrived. As usual, there are no witnesses to the crime, and it seems the local police officer is only hindering the city investigation team. How do you expect to find the murderer if the locals are unwilling to cooperate with the investigation, and the only clue is an antique gold pendant with an emerald that Maria was clutching in her hand? It's interesting where a girl like Masha, who barely makes ends meet, got such an expensive item? And why does the local librarian mourn for it the most, rather than her betrothed?...  The allure of gemstones has captivated and blinded people for centuries. Their power of attraction is so strong that people sometimes stop at nothing to possess them. This often leads to crimes that are told by the best detectives in the series "Criminal Stones."
