Hide and a shadow with a shadow

In the XVIII century in France, a noble adventurer Jeanne de Laudit turned a daring scam - stole a diamond necklace of extraordinary value and beauty belonging to the Queen of Maria Antoinette. According to legend, having staged her death, de Laustut settled in Russia, where she lived until the end of her days, but the unique necklace was never found. And for more than two hundred years, hundreds of people from all over the world have been hunting for him. Jeanne Okuneva, who found a cache in his house, was also drawn into this adventure, and soon attacked the robbers. However, there was no necklace in the cache - only the old notebook with the pages yellowed from time to scribbled with faded purple ink. But what if the notebook is the key to an invaluable treasure?
