Grasping for V. Group Read: first V. mention; second sighting

[Mark Kohut]

2/3 of the way down page 2, perennial edition: 

"overhead, turning everybody's face green and ugly, shone mercury-vapor
lamps, receding in an asymmetric V to the east where it's dark and there
are no more bars."   That V is not accidental, of course.

I ask you to remember street lamps in AtD and, I ask you to remember
receding V mercury-vapor lamps when we get to V and her age later in the book. 

V is ugly artificial light in descriptive association here...
