Lake of Darkness

Good is a construct. Evil is a virus.
The Starship Sa Niro and the Starship Sß Oubliette were in orbit around a black hole, one afternoon. . . by the end of the day, the crews of both starships were dead, victims of a single killer: Captain Alpha Raine.
Raine claims he's acting under the command of a voice emanating from the black hole: Mr Modo. No one believes him. Everyone knows that things go into black holes; nothing comes out.
But something inexplicable has been happening to Raine, and whatever it is seems to be spreading. An historian studying serial killers from the 21st century interviews him. . . and then nearly kills someone herself. It becomes increasingly undeniable that there's something inside that black hole. . . and it's found a way out. . .
