The fourth man had never been publicly identified in connection with the case.
His name was Franklin Mercer.
He had once served as the city's deputy finance director.
He was seventy-one now, retired, and widely respected for his work on municipal budgets.
The letter contained a sentence that made the records director stop reading.
The department did not begin stealing money when Matthews joined it. They learned how to make the theft look legal long before he received his badge.
Beneath that sentence, written in darker ink, were seven words.
Daniel Carter found the original accounts.
The director stared at the page.
Daniel Carter.
The mathematics teacher whose death had helped expose one of the most damaging police-corruption scandals in the city's history.
The older brother of Simone Carter.
For more than two decades, the public had understood his death as the result of an unlawful retaliatory arrest, falsified evidence, and medical neglect during detention.
The criminal proceedings had established serious misconduct.
The civil cases had produced settlements and institutional reforms.
But the letter suggested something the original investigation had never fully established.
Daniel had not merely challenged an abusive officer.
He might have discovered the financial architecture behind the entire scheme before federal investigators knew it existed.
And someone had spent twenty-three years keeping that possibility buried.
Simone was fifty-five when the director called.
She was living in a quiet suburban home outside the city, where she worked part-time as an adviser to a national public-integrity foundation.
Her professional life had expanded far beyond Riverside.
She had assisted organizations reviewing municipal contracting systems, delivered testimony before legislative committees, and helped design training programs that taught auditors how to distinguish administrative mistakes from coordinated fraud.
But she had deliberately resisted becoming a permanent public symbol.
She preferred work that produced records, procedures, and measurable improvements.
She no longer accepted every speaking invitation.
She rarely gave television interviews.
And she refused requests to turn her brother's death into a dramatic documentary without meaningful participation from his children.
On the morning of the call, she was preparing breakfast for her mother.
Her mother was eighty-four, physically frail but mentally alert, and had moved into Simone's home after a fall the previous winter.
Simone was slicing strawberries when her phone rang.
She glanced at the screen.
The director of the Riverside Public Accountability Resource Center.
She answered.
"Good morning."
"Ms. Carter, I'm sorry to call unexpectedly."
Simone set down the knife.
"What's happened?"
"We received some historical documents."
"About the old department?"
"Yes."
"Is there a records preservation problem?"
"Possibly. But there's something else."
The director hesitated.
Simone's expression tightened.
"Go ahead."
"The documents mention your brother."
Her hand became still.
For several seconds, the kitchen seemed unusually quiet.
Then she asked, "What do they say?"
The director explained what had arrived.
She described the photograph.
The financial statements.
The handwritten account.
And the allegation that Daniel had discovered the accounts underlying the towing scheme.
Simone listened without interrupting.
When the director finished, Simone looked through the kitchen window.
