Rublevsky Nocturne

On a rainy night in the luxurious mansion of oligarch Boris Mokhov, his young wife Liza is murdered. A priceless diamond necklace is missing. The only witness — the owner's son — is in shock, and the mysterious intrusion of... the criminal through the balcony leaves more questions than answers.
 
Famous detective Drongo takes on the case, unaware that beneath the mask of family well-being lies a web of lies, blackmail, and dark secrets of the past. Every inhabitant of the house has something to hide: both the oligarch's daughter from his first marriage, and the secretary who looks too much like the stepmother, and the nervous maid with two phones...
 
But when witnesses begin to die, Drongo realizes — he is dealing not with a simple robbery, but with something much more terrifying. A compromising video from Liza's past life becomes a deadly threat to everyone who learns about it...
 
In a world where the truth is worth more than life, and lies are the only salvation, Drongo will face the toughest choice of his career.
