We make promises too often, perhaps because we keep them much less often. But a promise given to a dying father is sacred... Even if during his lifetime you were not the most obedient and accommodating son.. And then... who could have guessed that such a simple request from his father - to take care of his half-sister - will turn into a series of incredible and dangerous adventures for his only son Nikolai. The heroes of books read in his youth: Count Cagliostro, Milady, Marie Antoinette, suddenly persistently declare themselves by bursting into such the understandable life of a young man devoid of all mysticism. They will demand help in returning the once stolen diamonds. Frightened and completely confused Nikolai Krapivin will turn to the clairvoyant Gloria with a request for help. But she will only offer to “revive” the painting “The Sharpie with the Ace of Diamonds” by dressing up as its heroes and waiting patiently... Sometimes waiting is the fastest and most correct solution to all problems... The book also includes an excerpt from the next novel “La Gioconda and Pagliacci.”< /p>
