“I’d expect any MP with a pulse to ask the obvious questions, whether or not they had a special unit transfer pending.”

“OK, I’m asking. General Kramer had a twenty-hour layover in the D.C. area and he wanted to get his rocks off and he didn’t mind paying for the privilege. So why did he drive all the way down here to do it? It’s what, three hundred miles?”

“Two hundred and ninety-eight,” I said.

“And then he’d have to drive all the way back.”

“Clearly.”

“So why?”

“You tell me,” I said. “Come up with something I haven’t thought of myself and I’ll recommend you for the transfer.”

“You can’t. You’re not my CO.”

“Maybe I am,” I said. “This week, anyway.”

“Why are you even here? Is something happening I should know about?”

“I don’t know why I’m here,” I said. “I got orders. That’s all I know.”

“Are you really a major?”

“Last time I checked,” I said.

“I thought 110th investigators were usually warrant officers. Working plain clothes or undercover.”

“They usually are.”

“So why bring you here when they could send a warrant officer and have him dress up as a major?”

“Good question,” I said. “Maybe one day I’ll find out.”

“May I ask what your orders were?”

“Temporary detached duty as Fort Bird ’s Provost Marshal’s executive officer.”

“The Provost Marshal isn’t on-post,” she said.

“I know,” I said. “I found that out. He transferred out the same day I transferred in. Some temporary thing.”

“So you’re acting CO.”

“Like I said.”

“MP XO isn’t a special unit job,” she said.

“I can fake it,” I said. “I started out a regular MP, just like you.”

Summer said nothing. Just drove.

“Kramer,” I said. “Why did he contemplate a six-hundred-mile round-trip? That’s twelve hours’ driving time out of his twenty. Just to spend fifteen bucks on a room and twenty on a whore?”

“Why does it matter? A heart attack is a heart attack, right? I mean, was there any question about it?”

I shook my head. “Walter Reed already did the autopsy.”

“So it doesn’t really matter where or when it happened.”

“His briefcase is missing.”

“I see,” Summer said.

I saw her thinking. Her lower eyelids flicked upward a fraction.

“How do you know he had a briefcase?” she said.

“I don’t. But did you ever see a general go to a conference without one?”

“No,” she said. “You think the hooker ran off with it?”

I nodded. “That’s my working hypothesis right now.”

“So, find the hooker.”

“Who was she?”

Her eyelids moved again.

“Doesn’t make sense,” she said.

I nodded again. “Exactly.”

“Four possible reasons Kramer didn’t stay in the D.C. area. One, he might have been traveling with fellow officers and didn’t want to embarrass himself in front of them by having a hooker come to his room. They might have seen her in the corridor or heard her through the walls. So he invented an excuse and stayed in a different place. Two, even if he was traveling alone he might have been on a DoD travel voucher and he was paranoid about a desk clerk seeing the girl and calling The Washington Post. That happens. So he preferred to pay cash in some anonymous dive. Three, even if he wasn’t on a government ticket he might have been a well-known guest or a familiar face in a big-city hotel. So likewise he was looking for anonymity somewhere out of town. Or four, his sexual tastes ran beyond what you can get from the D.C. Yellow Pages, so he had to go where he knew for sure he could get what he wanted.”

“But?”

“Problems one, two, and three could be answered by going ten or fifteen miles, maybe less. Two hundred and ninety-eight is completely excessive. And whereas I’m prepared to believe there are tastes that can’t be satisfied in D.C., I don’t see how they’re more likely to be satisfied way out here in the North Carolina boonies, and anyway I would guess such a thing would cost a lot more than twenty bucks wherever you eventually found it.”

“So why did he take the six-hundred-mile detour?”

She didn’t answer. Just drove, and thought. I closed my eyes. Kept them closed for about thirty-five miles.

“He knew the girl,” Summer said.

I opened my eyes. “How?”

“Some men have favorites. Maybe he met her a long time ago. Fell for her, in a way. It can happen like that. It can almost be a love thing.”

“Where would he have met her?”

“Right there.”

“Bird is all infantry. He was Armored Branch.”

“Maybe they had joint exercises. You should check back.”

I said nothing. Armored and the infantry run joint exercises all the time. But they run them where the tanks are, not where the grunts are. Much easier to transport men across a continent than tanks.

“Or maybe he met her at Irwin,” Summer said. “In California. Maybe she worked Irwin, but had to leave California for some reason, but she liked working military bases, so she moved to Bird.”

“What kind of a hooker would like working military bases?”

“The kind that’s interested in money. Which is all of them, presumably. Military bases support their local economies in all kinds of ways.”

I said nothing.

“Or maybe she always worked Bird, but followed the infantry to Irwin when they did a joint exercise out there one time. Those things can last a month or two. No point in hanging around at home with no customers.”

“Best guess?” I said.

“They met in California,” she said. “Kramer will have spent years at Irwin, on and off. Then she moved to North Carolina, but he still liked her enough to make the detour whenever he was in D.C.”

“She doesn’t do anything special, not for twenty bucks.”

“Maybe he didn’t need anything special.”

“We could ask the widow.”

Summer smiled. “Maybe he just liked her. Maybe she made damn sure he did. Hookers are good at that. They like repeat customers best of all. It’s much safer for them if they already know the guy.”

I closed my eyes again.

“So?” Summer said. “Did I come up with something you didn’t think of?”

“No,” I said.

I fell asleep before we were out of the state and woke up again nearly four hours later when Summer took the Green Valley ramp too fast. My head rolled to the right and hit the window.

“Sorry,” she said. “You should check Kramer’s phone records. He must have called ahead, to make sure she was around. He wouldn’t have driven all that way on the off chance.”

“Where would he have called from?”

“ Germany,” she said. “Before he left.”

“More likely he used a pay phone at Dulles. But we’ll check.”

“We?”

“You can partner with me.”

She said nothing.

“Like a test,” I said.

“Is this important?”

“Probably not. But it might be. Depends what the conference is about. Depends what paperwork he was taking to it. He might have had the whole ETO order of battle in his case. Or new tactics, assessment of shortcomings, all kinds of classified stuff.”

“The Red Army is going to fold.”

I nodded. “I’m more worried about red faces. Newspapers, or television. Some reporter finds classified stuff on a trash pile near a strip club, there’ll be major embarrassment all around.”

“Maybe the widow will know. He might have discussed it with her.”

“We can’t ask her,” I said. “As far as she’s concerned he died in his sleep with the blanket pulled up to his chin, and everything else was kosher. Any worries we’ve got at this point stay strictly between me, you, and Garber.”

“Garber?” she said.

“Me, you, and him,” I said.

I saw her smile. It was a trivial case, but working it with Garber was a definite stroke of luck, for a person with a 110th Special Unit transfer pending.

Green Valley was a picture-perfect colonial town and the Kramer house was a neat old place in an expensive part of it. It was a Victorian confection with fish-scale tiles on the roof and a bunch of turrets and porches all painted white, sitting on a couple of acres of emerald lawn. There were stately evergreen trees dotted about. They looked like someone had positioned them with care, which they probably had, a hundred years ago. We pulled up at the curb and waited, just looking. I don’t know what Summer was thinking about, but I was scanning the scene and filing it away under A for America. I have a Social Security number and the same blue and silver passport as everyone else but between my old man’s Stateside tours and my own I can only put together about five years’ worth of actual residence in the continental U.S. So I know a bunch of basic elementary-school facts like state capitals and how many grand slams Lou Gehrig hit and some basic high-school stuff like the constitutional amendments and the importance of Antietam, but I don’t know much about the price of milk or how to work a pay phone or how different places look and smell. So I soak it up when I can. And the Kramer house was worth soaking up. That was for sure. A watery sun was shining on it. There was a faint breeze and the smell of woodsmoke in the air and a kind of intense cold-afternoon quiet all around us. It was the kind of place you would have wanted your grandparents to live. You could have visited in the fall and raked leaves and drunk apple cider and then come back in the summer and loaded a ten-year-old station wagon with a canoe and headed for a lake somewhere. It reminded me of the places in the picture books they gave me in Manila and Guam and Seoul.
