One character in this work is shot after being distracted when a schoolboy comes out from under a table, and that character had earlier broken off an engagement by letter while trying to convince a dancer to go on with a performance.  Another character in this work is killed by Jack the Ripper after deciding to sleep with him for less than her normal fee, and earlier in this work had married a Painter after he did a portrait of her.  That character is loved by the lesbian Countess Geschwitz, and has sex with Alwa, the son of her third husband, on the same couch where his father bled to death.
