I WALKED IN THE HEAT ON INDEPENDENCE AS FAR AS THE AIR and Space Museum and then about-turned and headed for the library. I sat down on the steps fifty minutes into the hour. The stone was warm. There were men in uniform behind the doors above me, but none of them came out. Threat assessment exercises must have placed the library low on the list.

I waited.

I didn’t expect Sansom himself to show. I figured I would get staffers instead. Maybe campaign workers. How old and how many, I couldn’t guess. Between one and four, maybe, between post-grad and professional. I was interested to find out. One youngster would show that Sansom wasn’t taking my note very seriously. Four senior people would suggest he had sensitivity on the issue. And maybe something to hide.

The sixty minute deadline came and went and I got no staffers and no campaign workers, neither young nor old. Instead I got Sansom’s wife, and his head of security. Ten minutes after the hour was up, I saw a mismatched couple climb out of a Town Car and pause at the foot of the steps and look around. I recognized the woman from the pictures in Sansom’s hook. In person she looked exactly like a millionaire’s wife should. She had expensive salon hair and good bones and a lot of tone and was probably two inches taller than her husband. Four, in heels. The guy with her looked like a Delta veteran in a suit. He was small, but hard and wiry and tough. The same physical type as Sansom himself, hut rougher than Sansom had looked in his photographs. His suit was conservatively tailored out of good material, but he had it all hunched and creased like well-worn battledress.

The two of them stood together and glanced around at the people in the vicinity and eliminated one possibility after another. When I was all that was left I raised a hand in greeting. I didn’t stand. I figured they would walk up and stop below me, so if I stood I would be looking about three feet over their heads. Less threatening to stay seated. More conducive to conversation. And more practical, in terms of energy expenditure. I was tired.

They came up towards me, Mrs Sansom in good shoes, taking precise delicate steps, and the Delta guy pacing himself alongside her. They stopped two levels below me and introduced themselves. Mrs Sansom called herself Elspeth, and the guy called himself Browning, and said it was spelled like the automatic rifle, which I guessed was supposed to put it in some kind of a menacing context. He was news to me. He wasn’t in Sansom’s book. He went on to list his whole pedigree, which started out with military service at Sansom’s side, and went on to include civilian service as head of security during Sansom’s business years, and then head of security during Sansom’s House terms, and was projected to include the same kind of duty during Sansom’s Senate terms and beyond. The whole presentation was about loyalty. The wife, and the faithful retainer. I guessed I was supposed to be in no doubt at all about where their interests lay. Overkill, possibly. Although I felt that sending the wife from the get-go was a smart move, politically. Most scandals go sour when a guy is dealing with something his wife doesn’t know about. Putting her in the loop from the start was a statement.

She said, ‘We’ve won plenty of elections so far and we’re going to win plenty more. People have tried what you’re trying a dozen times. They didn’t succeed and you won’t, either.’

I said, ‘I’m not trying anything. And I don’t care about who wins elections. A woman died, that’s all, and I want to know why.’

‘What woman?’

‘A Pentagon clerk. She shot herself in the head, last night, on the New York subway.’

Elspeth Sansom glanced at Browning and Browning nodded and said, ‘I saw it on line. The New York Times and the Washington Post. It happened too late for the printed papers.’

‘A little after two o’clock in the morning,’ I said.

Elspeth Sansom looked back at me and asked, ‘What was your involvement?’

‘Witness,’ I said.

‘And she mentioned my husband’s name?’

‘That’s something I’ll need to discuss with him. Or with the New York Times or the Washington Post.’

‘Is that a threat?’ Browning asked.

‘I guess it is,’ I said. ‘What are you going to do about it?’

‘Always remember,’ he said. ‘You don’t do what John Sansom has done in his life if you’re soft. And I’m not soft either. And neither is Mrs Sansom.’

‘Terrific,’ I said. ‘We’ve established that none of us is soft. In fact we’re all as hard as rocks. Now let’s move on. When do I get to see your boss?’

‘What were you in the service?’

‘The kind of guy even you should have been scared of. Although you probably weren’t. Not that it matters. I’m not looking to hurt anyone. Unless someone needs to get hurt, that is.’

Elspeth Sansom said, ‘Seven o’clock, this evening.’ She named what I guessed was a restaurant, on Dupont Circle. ‘My husband will give you five minutes.’ Then she looked at me again and said, ‘Don’t come dressed like that, or you won’t get in.’

They got back in the Town Car and drove away. I had three hours to kill. I caught a cab to the corner of 18th Street and Mass Avenue and found a store and bought a pair of plain blue pants and a blue checked shirt with a collar. Then I walked on down to a hotel I saw two blocks south on 18th. It was a big place, and quite grand, but big grand places are usually the best for a little off-the-books convenience. I nodded my way past the lobby staff and took an elevator tip to a random floor and walked the corridor until I found a maid servicing an empty room. It was past four o’clock in the afternoon. Check-in time was two. Therefore the room was going to stay empty that night. Maybe the next night, too. Big hotels are rarely a hundred per cent full. And big hotels never treat their maids very well. Therefore the woman was happy to take thirty bucks in cash and a thirty-minute break. I guessed she would move on to the next room on her list and come back later.

She hadn’t gotten to the bathroom yet, but there were two clean towels still on the rack. Nobody could possibly use all the towels that a big hotel provides. There was a cake of soap still wrapped next to the sink and half a bottle of shampoo in the stall. I brushed my teeth and took a long shower. I dried off and put on my new pants and shirt. I swapped my pocket contents over and left my old garments in the bathroom trash. Thirty bucks for the room. Cheaper than a spa. And faster. I was back on the street inside twenty-eight minutes.

I walked up to Dupont and spied out the restaurant. Afghan cuisine, outside tables in a front courtyard, inside tables behind a wooden door. It looked like the kind of place that would fill up with power players willing to drop twenty bucks for an appetizer worth twenty cents on the streets of Kabul. I was OK with the food but not with the prices. I figured I would talk to Sansom and then go eat somewhere else.

I walked on P Street west to Rock Creek Park, and clambered down close to the water. I sat on a broad flat stone and listened to the stream below me and the traffic above. Over time the traffic got louder and the water got quieter. When the clock in my head hit five to seven I scrambled back up and headed for the restaurant.
