This poor creature has been incarcerated. What was her crime? She does not know.
There is plenty of time to contemplate her fate, however, and she is attempting to gain a panoramic view of her plight. For some reason the events that led to her imprisonment are murky and elusive.
She remembers working at the piano bar as she always does on Tuesday nights, and meeting a very nice gentleman with whom she socialized after work... and then nothing. Her memory stops there.
And so she waits in her cell. Sooner or later the authorities will come and charge her with a crime, which should shed some light on things, she reasons.
Let us hope they come soon...
