Nobody knew she had already reviewed thousands of pages of contracts, property transactions, and bank records obtained through lawful investigative procedures.
Nobody knew she was watching the ballroom entrances more carefully than the decorations.
And nobody knew that a black evidence case waiting in a service office upstairs contained material capable of changing the future of the city's police department.
She had attended the gala under an authorized undercover identity as a wealthy investor interested in regional development projects.
The dress was part of that cover.
She had chosen it carefully.
The champagne fabric looked luxurious without being flashy. Its sculpted corset made a strong impression, while the elegant lines of the skirt gave her the confident appearance of someone accustomed to private receptions and expensive rooms.

A beautiful woman in an expensive designer dress, apparently interested in investing money, could make certain men dangerously eager to talk.
She had learned that lesson early in her career.
Not because she believed beauty was power.
Because she understood that people often revealed their assumptions before they revealed their secrets.
And assumptions could be useful.
At the center of the investigation was a housing redevelopment fund established after a series of severe storms damaged neighborhoods across the county.
The fund had received substantial public assistance money intended to repair homes, relocate vulnerable families temporarily, and restore essential infrastructure.
Hundreds of residents had applied for help.
