“Two Thirds of a Ghost” is an old parlor game where a participant who does not answer the next question loses a third of his right to continue playing. Anyone who does not answer three questions is eliminated from the game. He becomes a ghost. The innocent game will be the last event in the life of one of the participants. After drinking potassium cyanide, he turns from an imaginary ghost into a real retired player. The first steps of the investigation lead to new mysteries - who was the deceased in life? His personality is as illusory as a bad game. With this book, the Nezavisimaya Gazeta publishing house continues the “Murder Writer” series of detective stories about crimes related to literature and art.
