“I have,” I said, pulling off my parka. The snow had followed me all the way from White Sulphur Springs and then turned into icy rain fifty miles from D.C. I was glad Broun had a fire going in his upstairs study. “I found out what you wanted to know about Traveller.”

“Good, good,” he said, taking books off a straight-backed chair and setting it in front of the fire. He draped my wet parka over the back of it. “I’m glad you’re home, Jeff. I think I’ve finally got a handle on the book. Did you know Lincoln dreamed about his own assassination?”

“Yes,” I said, wondering what on earth this had to do with a novel about Antietam. “He dreamed he saw his dead body in the White House, didn’t he?”

“He dreamed he woke up and heard the sound of crying,” Broun said, dumping his Siamese cat out of his big leather armchair and pulling it around to face the fire. He didn’t seem to be in any hurry, even though the reception was supposed to start at seven. He was wearing the ratty-looking gray cardigan he usually wrote in and a pair of baggy pants, and he apparently hadn’t shaved since I’d left. Maybe they’d canceled the reception after all.

Broun motioned me to sit down. “When he went downstairs he couldn’t see anyone,” he went on, “but there was a corpse lying in a coffin in the East Room. The corpse’s face was covered by a black cloth, and Lincoln asked the guard standing at the door who was dead, and the guard answered, The President. He was killed by an assassin.’”

He was looking at me eagerly, waiting for me to say something, but I didn’t have a clue of what that something was supposed to be. “He had the dream, what, a month before he died?” I said lamely.

“Two weeks. April the second. I’d read it before, but while you were gone, McLaws and Herndon’s publicist called and asked me what book I was going to do after The Duty Bound . She needed it for the press release they’re going to pass out at the reception tonight, and I told her I didn’t know, but then I got to thinking about the Lincoln book.”
