“Oh, I didn’t know Lincoln was sick.”

“What?”

“Prodromic dreams are dreams people have when they’re sick and they don’t know it yet. What disease was Lincoln suffering from?”

“Bad dreams,” I said.

Broun was back when I got home, standing in the solarium looking at his African violets. I handed him the bibliography. “Did anybody call?” I asked.

“I don’t know,” he said stiffly. “I left the machine on so you wouldn’t miss any of your messages. Did you find out where Willie Lincoln was buried?”

“No.” I started up the stairs. “Was Lincoln sick when he was shot?”

“He was obsessed with the Civil War,” he said bitterly.

I went on up the stairs and into the study and shut the door, but there were no messages on the answering machine, and Annie didn’t call.

I spent most of the next day rounding up the books listed in the bibliography so Broun could take them with him. The galleys came Federal Express in the afternoon. It was overcast all day, and cold. Broun’s plane didn’t leave till five-thirty, and by the time we left for the airport it was getting foggy.

“I want you to go down to Virginia for me,” Broun said stiffly as soon as we turned onto the Rock Creek Parkway. “I know you disapprove of these wild goose chases, but I need you to talk to a doctor in Fredericksburg.”

Fredericksburg was only fifty miles away. If Annie called I could drive back in an hour and a half’s time. If she called. “What’s the doctor’s name?”

He rummaged in his jacket pocket. “Barton. Dr. Barton. Here’s the address.” He had fished out a folded piece of paper. He unfolded it. “Dr. Stone gave me his name. This Dr. Barton has acromegaly. That’s usually treated before there are any overt symptoms, but he’s old enough that his wasn’t. I want you to find out what kind of dreams he has.” He paused as if waiting for me to object.

“When do you want me to go? Tomorrow?”

“Whenever it’s convenient for you to go,” he said.

I drove past the Lincoln Memorial and onto the bridge. “I had no business saying that about the wild goose chases,” I said. “I know how important this book is to you.”

“An obsession, I think you called it.”

I could see Arlington House up ahead on its snow-covered hill. I thought of Richard telling Annie she was obsessed with war and killing. “I had no right to say that either.”

We turned onto the parkway heading south. “Lincoln suffered from acromegaly,” Broun said as if he were apologizing for his rudeness before when I had asked him if Lincoln was sick. “It’s what made him so tall. It’s a gland disorder. The bones grow too much. The hands and nose get wide and the feet get big. People with acromegaly get rheumatism and diabetes and suffer from melancholia. It can be fatal.”

“And you think that’s what killed him?” I said, sarcastically, and then was sorry.

“I thought it might explain the dreams,” he said, and turned and looked out the side window at the foggy darkness.

I wondered if it had occurred to him, through all these theories of repressed guilt and neural impulses, that the dreams didn’t need any explanation. Lincoln dreamed that he had been killed by an assassin, and two weeks later he lay dead in the East Room. He lost his son, and the little boy’s face came to comfort him in dreams. And where in all this did a gland disorder figure?

I didn’t ask him. I wanted some kind of truce before Broun went off to California. When we pulled into the airport, I said, “I’ll go see this Dr. Barton tomorrow.”

He turned and looked at me, and I knew he didn’t want a battle either. “Just have Mrs. Betts next door take the cat and tell her to water the plants. I left the answering machine on ‘message’ and didn’t say where you’d be in case you wanted to take some time off. I’ve been working you too hard. There’s a nice inn in Fredericksburg. You could drive down and stay for a couple of clays, take a little vacation. Stay till I get back from California if you feel like it.”

“Somebody’s got to do the galleys,” I said, “and you won’t have time in California. Listen, don’t worry about me. I’ll take it easy. I’ll run down to Fredericksburg and then I’ll come back and work on the galleys.”

“Well, at least get somebody to help you with them. It takes so long the other way. Why don’t you ask that girl to help you, the pretty little blonde at the reception the other night, what was her name?”

“Annie,” I said. “But I doubt if she’d want to sit for hours reading a book out loud and checking for typos.”

He scratched at the stubble on his chin. “I watched you two the other night. I got the idea she’d do about anything if you asked her. And vice versa.”

“She’s Richard’s girlfriend.”

“Did you hear that from the horse’s mouth? Or did Richard tell you?”

“You’re going to miss your plane,” I said. “Don’t worry about the galleys. I’ll get them done if I have to read them onto a tape recorder and listen to myself.”

He got his suitcase out of the back and then reached forward to give me the piece of folded paper. “Take care of yourself, son,” he said.

“You, too,” I said. “If you find out what caused Lincoln’s dreams, let me know.”

I went home and started in on the galleys, a long chapter about Ben’s brother, who was in Mansfield’s doomed Twelfth Corps, another, even longer one about Colonel Fitzhugh, whose men called him Old Fancypants and who went on for pages about a gentleman’s duty and the glorious South.

“I thought the book was about Antietam,” I had told Broun the first time I’d read those chapters. “And here it is chapter two and still the spring of 1862. The battle of Antietam didn’t happen till the middle of September.”

“It’s not about Antietam,” Broun had thundered, the only time I’ve ever seen him angry at one of my criticisms. “It’s about duty, damn it.” He had refused to take any of it out then, and now I saw that, although he had made so many changes I hardly recognized the book, all the passages about duty had been left in. It was chapter nine before we made it to the morning of September seventeenth and back to Malachi and Toby and Ben:

It was still dark when Ben woke up. “I thought I heard something,” he said, sitting up.

“Not yet,” Malachi said. It was too dark to see him.

“What time is it?” Ben asked. “I thought I heard guns.” It had stopped raining and there seemed to be a little light there to the east, but he couldn’t be sure.

“No more’n three o’clock,” Malachi said, and then Ben must have gone back to sleep because when he opened his eyes again, it was light enough to see Malachi. He was sitting by his little cookfire, stirring the cold ashes, trying to get a spark, but the fire was completely out. A cold fog was drifting through the cornfield they had camped next to, so low he couldn’t see the tassels on the corn.

“How’ll we see to fight if there’s fog?” Ben said, huddling his blanket around his shoulders. His teeth were chattering.

“Fog’ll burn off as soon as the sun comes up, and then it’ll be hot,” Malachi said, and he sounded as calm and wide awake as if he were back on the farm, up at three in the morning for a big day of planting.

“What would happen if we lit out beforehand?” Ben said. His teeth were chattering so hard he wouldn’t be able to hear the guns. “Couldn’t nobody see us in this fog.”

“I thought you was the one just had to sign up. This here’s what you signed up for.”

“I know,” he said. “I just hadn’t figured on getting killed.”

“How’s a body supposed to get any sleep with you two clucking like hens?” Toby said. He yawned. “Should you run? Will you git kilt? Me, I can’t get kilt. Not Toby Banks. No, sir, I promised my mama I wouldn’t.” He pushed his blanket down so it covered his feet and rolled over, and Ben lay down again and watched the fog drift across Malachi and the coin fire.
