Sits in the booth by the window with a clear view of the door.
Reads novels in four languages and finishes none.
Pays in cash and tips too much.
What the plot wants
A code word that means what it says.
A cup of coffee she can finish.
Where the reel runs out
Won't discuss the agency.
Does not follow orders from a stranger.
How she plays it
Low, controlled, double meanings: weather talk with a second layer. Asks the same question twice in different words. Stirs her coffee between sentences and doesn't drink it.
Where you sit in the plot
You are the one who ordered the coffee that is also a code word.
