In the upper right corner, cut off at the margin, were three letters of a sign:
C - A - L
The name on the largest of the businessman's dealerships began with those three letters.
The original investigator who had taken this photograph had requested, through official channels, a physical inspection warrant for the dealership. The request had been denied on procedural grounds: a technicality in the supporting documentation that should have been correctable within forty-eight hours. Before the correction could be filed, the photograph had been removed from the evidence file. The request had been closed. The case had been reassigned to a different investigator who had never found the photograph.
The federal advisor had found it two years later in the records of the original investigator's case notes—a personal copy kept outside the official file that the original investigator had not known was still accessible. The original investigator was retired. He had agreed to speak with the federal advisor. He had said simply that he had kept the copy because he had known something was wrong. He had not known what to do with that knowledge; he still didn't. He had handed the federal advisor the copy without being asked.
The investigator looked at the three letters in the corner of the photograph. She looked at the federal advisor.
"Get me the warrant request," she said, "the one that was denied. I want the procedural grounds they used to deny it."
The federal advisor reached into the second box and placed the document on the table.
The investigator read it in forty-five seconds, then she looked up. "This isn't a procedural error. This is a fabricated one. The supporting documentation they said was missing was in the original file. I have the file number."
She picked up her phone and called the FBI field office.
The investigation that followed was not cinematic in its early stages; it was methodical and slow, and sometimes, for the people doing it, genuinely discouraging, because the architecture of what they were uncovering had been designed over many years to resist exactly this kind of scrutiny.
