I Is for Innocent

murder trial shortly after he was acquitted. He says the cameras were rolling as the guy left the courtroom, so if what he says is true, he ought to be clearly visible on the tape, right?"
    "Yeeess," he said slowly. I could tell he thought there was some kind of trick to it.
    "This isn't a violation of anybody's civil rights," I said reasonably. "Could you just look?"
    He held his hand out. I gave him Curtis's mug shot. He continued to hold his hand out.
    I stared for a moment. "Oh," I said. I opened my handbag and took out my wallet. I peeled off a twenty and put it in his palm. His expression didn't actually change, but I knew he was insulted. I'm sure it's the same look you'd get from a New York taxi driver if you tipped him a dime.
    I peeled off another twenty. No reaction. I said, "I really hate corruption in someone so young."
    "It's disgusting, isn't it?" he replied.
    I added a third.
    His hand closed. "Come with me."
    He turned and headed back through the doorway and into a narrow corridor. I followed without a word. Offices opened up on either side of us. Occasionally, we passed other station employees wearing jeans and Reeboks, but no one was doing much. The spaces seemed cramped and irregular, with too much knotty pine veneer paneling and too many cheaply framed photographs and certificates. The whole interior of the building had been done up with the sort of do-it-yourself home improvements that later make a house impossible to sell.
    At the rear, we passed into a tiny concrete cul-de-sac with a wood-and-metal stairway leading up to an attic. Just to the right was an old-fashioned wooden file cabinet, with a smaller wooden file sitting on top. He opened the drawer for the year we wanted and began to sort through the index cards, starting with the name Barney. "We won't have the actual field tapes," he remarked while he looked.
    "What's a field tape?"
    "That would be like the whole twenty minutes of tape the guy shot. We keep the ninety seconds to two minutes of edited footage that actually goes on the air."
    "Oh. Well, even that would help."
    "Unless the guy you're looking for stepped up and spoke to your suspect after the cameras finished rolling."
    "True enough," I said.
    "Nope. Nothing," he said. "Well, let's see here. What else could it be under?" He tried "Murder,"
    "Trials," and "Courtroom Cases," but there was no reference to Isabelle Barney.
    "Try 'Homicides,' " I suggested.
    "Oh, good one." He shifted to the H's. There it was, with a numerical designation that apparently referred to the number of the tape on file. We went up the narrow stairs and through a door so low we were forced to duck our heads. Inside, there was a warren of tiny rooms with six-foot ceilings, lined with videocassette containers, neatly labeled and filed upright. Leland located and retrieved the cassette we were looking for and then led me downstairs again and around to the right where there were four stations set up with monitoring equipment. He flipped on the first machine and inserted the tape. The first segment appeared on the screen in front of us. He pressed Fast Forward. I watched the news for that year whiz by like the history of civilization in two minutes flat, everybody very animated and jerky. I spotted a still of Isabelle Barney. "There she is," I yelped.
    Leland backed the tape up and began to run it at normal speed. An anchorperson I hadn't seen for years was suddenly doing the voice-over commentary as snippets of the case, neatly spliced together, spelled out the highlights of Isabelle's death, David Barney's arrest, and the subsequent trial. The acquittal, in condensed form, had the speedy air of instant justice, well edited, swiftly rendered, with liberty for all. David Barney emerged from the courtroom looking slightly dazed.
    "Hold it. Let me look at him."
    Leland stopped the tape and let me study the image. He was in his forties with light brown wavy hair combed away from his face. His forehead was lined and there were lines radiating from the corners of his eyes. He had a straight nose and a tense grin over artificially even teeth. His chin was strong and I could see that he had strong hands with blunt-cut nails. He was slightly taller than medium height. His attorney looked very tall and gray and somber by comparison.
    "Thanks," I said. I realized belatedly that I'd been holding my breath. Leland pushed Play and the coverage quickly switched to another subject altogether. He handed me Curtis McIntyre's
