I stepped out to the hallway again. Listened hard. Heard nothing. I could have searched the house, but I didn’t need to. I was pretty sure there was nobody in it and I knew there was nothing I needed to find. So I took a last look at the Kramer widow. I could see the soles of her feet. She hadn’t been a widow for long. Maybe an hour, maybe three. I figured the blood on the floor was about twelve hours old. But it was impossible to be precise. That would have to wait until the doctors arrived.

I retreated through the kitchen and went back outside and walked around to find Summer. Sent her inside to take a look. It was quicker than a verbal explanation. She came out again four minutes later, looking calm and composed. Score one for Summer, I thought.

“You like coincidences?” she said.

I said nothing.

“We have to go to D.C.,” she said. “To Walter Reed. We have to make them double-check Kramer’s autopsy.”

I said nothing.

“This makes his death automatically suspicious. I mean, what are the chances? It’s one in forty or fifty thousand that an individual soldier will die on any given day, but to have his wife die on the same day? For her to be a homicide victim on the same day?”

“Wasn’t the same day,” I said. “Wasn’t even the same year.”

She nodded. “OK, New Year’s Eve, New Year’s Day. But that just makes my point. It’s inconceivable that Walter Reed had a pathologist scheduled to work last night. So they had to drag one in, specially. And from where? From a party, probably.”

I smiled, briefly. “So you want us to go up there and say, hey, are you sure your doc could see straight last night? Sure he wasn’t too juiced up to spot the difference between a heart attack and a homicide?”

“We have to check,” she said. “I don’t like coincidences.”

“What do you think happened in there?”

“Intruder,” she said. “Mrs. Kramer was woken up by the noise at the door, got out of bed, grabbed a shotgun she kept near at hand, came downstairs, headed for the kitchen. She was a brave lady.”

I nodded. Generals’ wives, tough as they come.

“But she was slow,” Summer said. “The intruder was already all the way into the study and was able to get her from the side. With the crowbar he had used on the door. As she walked past. He was taller than she was, maybe by a foot, probably right-handed.”

I said nothing.

“So are we going to Walter Reed?”

“I think we have to,” I said. “We’ll go as soon as we’ve finished here.”

We called the Green Valley cops from a wall phone we found in the kitchen. Then we called Garber and gave him the news. He said he would meet us at the hospital. Then we waited. Summer watched the front of the house, and I watched the back. Nothing happened. The cops came within seven minutes. They made a tight little convoy, two marked cruisers, a detective’s car, an ambulance. They had lights and sirens going. We heard them a mile away. They howled into the driveway and then shut down. Summer and I stepped back in the sudden silence and they all swarmed past us. We had no role. A general’s wife is a civilian, and the house was inside a civilian jurisdiction. Normally I wouldn’t let such fine distinctions get in my way, but the place had already told me what I needed to know. So I was prepared to stand back and earn some Brownie points by doing it by the book. Brownie points might come in useful later.

A patrolman watched us for twenty long minutes while the other cops poked around inside. Then a detective in a suit came out to take our statements. We told him about Kramer’s heart attack, the widow trip, the banging door. His name was Clark and he had no problem with anything we had to say. His problem was the same as Summer’s. Both Kramers had died miles apart on the same night, which was a coincidence, and he didn’t like coincidences any better than Summer did. I started to feel sorry for Rick Stockton, the deputy chief down in North Carolina. His decision to let me haul Kramer’s body away was going to look bad, in this new light. It put half the puzzle in the military’s hands. It was going to set up a conflict.

We gave Clark a phone number where he could reach us at Bird, and then we got back in the car. I figured D.C. was another seventy miles. Another hour and ten. Maybe less, the way Summer drove. She took off and found the highway again and put her foot down until the Chevy was vibrating fit to bust.

“I saw the briefcase in the photographs,” she said. “Did you?”

“Yes,” I said.

“Does it upset you to see dead people?”

“No,” I said.

“Why not?”

“I don’t know. You?”

“It upsets me a little.”

I said nothing.

“You think it was a coincidence?” she said.

“No,” I said. “I don’t believe in coincidences.”

“So you think the postmortem missed something?”

“No,” I said again. “I think the postmortem was probably accurate.”

“So why are we driving all the way to D.C.?”

“Because I need to apologize to the pathologist. I dropped him in it by sending him Kramer’s body. Now he’s going to have wall-to-wall civilians bugging him for a month. That will piss him off big time.”

But the pathologist was a her, not a him, and she had such a sunny disposition that I doubted anything could piss her off for long. We met with her in the Walter Reed Army Medical Center ’s reception area, four o’clock in the afternoon, New Year’s Day. It looked like any other hospital lobby. There were holiday decorations hanging from the ceilings. They already looked a little tired. Garber was already there. He was sitting on a plastic chair. He was a small man and didn’t seem uncomfortable. But he was quiet. He didn’t introduce himself to Summer. She stood next to him. I leaned on the wall. The doctor faced us with a sheaf of notes in her hand, like she was lecturing a small group of keen students. Her name badge read Sam McGowan, and she was young and dark, and brisk, and open.

“General Kramer died of natural causes,” she said. “Heart attack, last night, after eleven, before midnight. There’s no possibility of doubt. I’m happy to be audited if you want, but it would be a complete waste of time. His toxicology was absolutely clear. The evidence of ventricular fibrillation is indisputable and his arterial plaque was monumental. So forensically, your only tentative question might be whether by coincidence someone electrically stimulated fibrillation in a man almost certain to suffer it anyway within minutes or hours or days or weeks.”

“How would it be done?” Summer asked.

McGowan shrugged. “The skin would have to be wet over a large area. The guy would have to be in a bathtub, basically. Then, if you applied wall current to the water, you’d probably get fibrillation without burn marks. But the guy wasn’t in a bathtub, and there’s no evidence he ever had been.”

“What if his skin wasn’t wet?”

“Then I’d have seen burn injuries. And I didn’t, and I went over every inch of him with a magnifying glass. No burns, no hypodermic marks, no nothing.”

“What about shock, or surprise, or fear?”

The doctor shrugged again. “Possible, but we know what he was doing, don’t we? That kind of sudden sexual excitement is a classic trigger.”

Nobody spoke.

“Natural causes, folks,” McGowan said. “Just a big old heart attack. Every pathologist in the world could take a look at him and there would be one hundred percent agreement. I absolutely guarantee it.”

“OK,” Garber said. “Thanks, Doc.”

“I apologize,” I said. “You’re going to have to repeat all that to about two dozen civilian cops, every day for a couple of weeks.”

She smiled. “I’ll print up an official statement.”

Then she looked at each of us in turn in case we had more questions. We didn’t, so she smiled once more and swept away through a door. It sucked shut behind her and the ceiling decorations rustled and stilled and the reception area went quiet.
