Seventh execution

The house was too great for her alone, but Claudia lived in him because her son built him ... a son who died three days before the wedding. Fleeing from loneliness, Klava surrounded herself with friends. And with all of them she discussed her death. She was not afraid of her, but she did not rush. Claudia planned to die five years later from a heart attack, but she died much earlier. One of those who she surrounded herself did not go crazy ...
Who did it? Best friend? The failed daughter -in -law? An old fan who has not achieved reciprocity? The only relative who dreams of becoming the heiress? Or did she take revenge on a person who had been copied offense for many years, and about which Claudia has long forgotten?
