Nancy Drew and the disappeared relic

My name is Nancy Drew. And I am a detective. Of course, I don’t have a badge and a pistol yet, but I always pay attention to injustice, deception and vile actions and I know how to stop the villains. I revealed a lot of crimes and is ready to share these stories with you.
I have to reveal a difficult matter. Recently, the young Frenchwoman Simon Valinkovskaya bought an old house on our street. As soon as she settled here, a misfortune happened: the Faberge egg, inherited from the Russian grandfather, was stolen in broad daylight. The rest of the jewelry and expensive things remained untouched. I will definitely calculate the criminal, because for Simon it is not just a jewelry, but a family relic dear to my heart
