Unreadable Mysteries

This is a mystery you cannot read.
No trail of clues, no puzzles to resolve
no clever sleuth a-hunt as fogs dissolve
in gaslight. Empty streets and voiceless need
the backwash of a heartless city's greed--
the tropes of noir don't make this plot revolve.
Nor are our heroes struggling to absolve
themselves of some long-hidden sorry deed
by doing good. No, here's our secret text:
the paths untaken, stories that have forked
from common root, but grown beyond our sight.
Who drank the wine from bottles I left corked,
who slept while I went dancing every night,
and when, my heart, will she and I meet next?
