We walked past the hallway where, a year earlier, he had stood looking like a man who had misplaced the ground beneath him.

“Do you miss the old job?” I asked as we crossed the parking lot.

“Sometimes,” he said.

“Mostly I miss being able to believe the right evidence would always lead to the right result.”

“Did you ever believe that?”

“I believed it often enough to keep working.”

We laughed softly.

On the drive home, he told me about a case from early in his career that he had never mentioned before.
