A line of shiny black vehicles came roaring up toward him, brightly lit from within and spewing odd-smelling diesel fumes. All of them built with technology stolen—or, more likely, purchased—from the Texians, and spreading across the continent with speed that couldn’t bode well for the Confederacy. Texas tech was one of their last remaining advantages, and it, too, was slipping from their grasp.

This thought made him smile glumly as he plodded forward. His feet had become blocks of ice, and his hands gone likewise numb. His gloves were back at the old hospital in the basement somewhere, lying atop the Fiddlehead. Had the roof held, or had the dynamite brought the whole wing crashing down upon the calculation engine?

Gideon’s pace slowed, then picked up again. Worrying wouldn’t change whatever facts awaited him back there, and he couldn’t return to find out. Not until morning, he suspected, and maybe not even then.

If the Fiddlehead survived, then it must survive as a secret.

He squinted against brilliant pairs of front-facing lamps. As one of the cars passed him, he heard laughter within. And music. Someone had brought a violin, and someone else was playing a fife. Despite the cold, some of the carriages had left their windows down, and as they rolled past, Gideon smelled expensive food and perfume, and alcohol and tobacco.

Somewhere in the city, a ball or some other gala event had just ended, and a beautiful room filled with finely presented tables was emptying, which meant that Mrs. Lincoln might not be home yet. She often lingered at these things, partly by her own preference and partly because she served as her husband’s social eyes and ears, for the former president rarely left the house since his near-fatal injury at Ford’s Theatre. It was too trying, he said; too much trouble for other people to accommodate him. So he kept to his own home and his own grounds, which had been altered to better suit his needs.

Gideon kept his eyes open on the off chance Mrs. Lincoln’s buggy might pass by and he could flag her down, but it was not his lucky night. He walked the full distance, and by the time he reached the Lincoln estate his legs were heavier than lead.

So far as estates went, it was a surprisingly modest one—at least from the exterior; the inside was filled with expensive gifts collected over the years from dignitaries near and far. The house itself was a simple two-story home with two wings, and a lift inside, for the president could not ascend stairs without immense assistance. Also due to Lincoln’s mechanized chair, all the outdoor paths were paved.

Gideon almost tripped over the first walkway he passed. He might have cursed except that he was so relieved to have arrived. Lights burned up the hill at the homestead, giving him more than the nighttime sky or traffic to navigate by. He homed in on these electric torches, drawn like the moths and mosquitoes that hovered around the devices in a buzzing cloud. Up the half-dozen stairs he climbed, bypassing the ramp because it was less direct. Even after his long, cold hike, he was more impatient than tired.

The front door opened before he could knock, and there stood a confused-looking Nelson Wellers.

Mr. Lincoln’s personal physician was a gaunt young man with a cadaverous complexion. He was quick and capable, but he always wore the expression of someone carrying the weight of the world. Friendly enough despite his nervous disposition, he was well liked and trusted, even by Gideon, who had worked with him before. Together they had designed and perfected the ex-president’s wheeled chair, as well as some of the other tools that made life easier for the badly crippled politician.

“Gideon!” Nelson cried. “There you are—thank God!”

“Not a greeting I get every day.”

The doctor reached out and grabbed the scientist by the coat lapels, drawing him bodily inside and shutting the door behind them both. “We just heard about the explosion, and Ephraim said there was no sign of you out at the Jefferson building. I was on my way to … to … to see if I could find you, I suppose. Did you walk all the way back?”

“Yes.”

“Dear God, it’s freezing out there.”

“No, not quite.”

From the parlor doorway, a woman gasped. “Oh, Mr. Bardsley!”

Gideon threw her a nod, but did not make eye contact. “Polly,” he greeted the household lady-in-waiting, as Mrs. Lincoln often called her. One part maid, one part nurse, Polly Lockhart was a girl of mixed and indeterminate race—more white than otherwise. She was stout and small, much like the former first lady herself. She wrung her hands together, so they’d have something to do besides flutter.

“Dr. Wellers was just about to go looking for you.”

“So he says.”

The doctor went to the nearby liquor cabinet and poured himself a stiff draught of very good bourbon, then offered one to Gideon, too. He shifted his bundle of paper and accepted the glass, knowing better than to hope it’d warm his feet, but appreciating the gesture. The beverage and the crystal service set beside it were a gift from a French ambassador, and easily worth more than his niece. He knew, because ten years ago he’d bought her freedom when he couldn’t steal it. The cost of the furnishings could have brought many more families across the line. The math filled his head but did not make it spin. Very few things could accomplish such a feat, least of all numbers.

Gideon downed the drink and watched the new electric lights sparkle through the damp crystal.

One of Polly’s fluttering, fretful hands touched his arm. “What happened out there?” she asked. “Can I help you with your … with this … package?”

“No, Polly. I’ve got it under control. Two men broke in,” he answered her first question, handing the glass back to Nelson and glancing at his feet. He still couldn’t feel them, but he watched as they dripped and oozed a large damp spot on a very expensive rug from somewhere in the Ottoman empire.

“Are you sure you aren’t hurt?” the doctor tried again, scrutinizing Gideon with a professional appraisal that was already telling him that all was well. “Can Polly take your coat?” he asked, his dubious tone suggesting he already knew the answer to that, too.

“No,” Gideon replied, a little too quickly. “No, I’ll just sit a minute by the fire, if you don’t mind. I need to see Mr. Lincoln.” He squeezed the printout. It felt strange, like it had shrunk on the way from the hospital. But it’d only become crushed as he’d kneaded it down, over and over again, making sure he didn’t drop it. “He needs to see this. This is what they came for.”

He barely heard the faint motor hum of the president’s chair approaching, but he did hear it because he expected it, and he listened for it.

Nelson Wellers stood aside, and Polly withdrew to the edge of the room. Gideon stayed where he was, and the sixteenth president of the United States rolled into their midst.

His chair was a marvel of science, the only one of its kind. Propelled by an electric motor, it was manipulated with small levers and buttons, customized for the old man’s long, slender hands. Those fingers, which had once signed laws into being, were crumpled now, bending and unbending only with great effort; but they were firm on the steering paddle as he brought himself forward.

This was the man who would’ve freed Gideon’s family, if he’d had the chance. If the bullet hadn’t blown his head almost in two, leaving him a stiff, twisted figure made of scars and odd angles. He was a hero. That made Gideon a hero by proxy, so far as his mother and brothers were concerned. His mother told everyone about it: how her boy worked hand in hand with the great leader, coming into his house through the front door like a proper gentleman. Her gushing pride embarrassed him for complicated reasons—reasons he never shared, because they would’ve only confused her.

Abraham Lincoln gazed levelly at the scientist with his one good eye. “Gideon, you did it.”

Not a question, but a statement of certainty. Abraham Lincoln liked to be certain, almost as much as Gideon did.

“Yes sir, but this is all I could save. I needed more time.”

“We always do.” The former president nodded solemnly, his thin frame bobbing softly in the narrow black suit he so often wore. “It will have to be enough.” He gestured toward the library, and turned the chair to face it. “Polly,” he called over his shoulder. “Could you bring Dr. Bardsley a pair of slippers? Something from my closet, to wear until his boots are dry.”

“Yes, sir. I will, sir.”

To Gideon, he said, “You can take those off, and we’ll put them by the fire. Your feet must be miserable.”

“Yes, they are. Thank you, sir.” He followed the chair he’d helped build, and Nelson Wellers fell into step beside him.

Speaking over his shoulder again, for he could not easily turn his head, Mr. Lincoln said, “I’m glad to see you escaped unscathed, Gideon. When we got word of the blast, I feared the worst. But Ephraim said he didn’t see any sign of you, not in the rubble—or in the basement either, when he dropped a lantern down there. You barely missed one another. He rode out on horseback and only just returned. You made awfully good time on those frozen feet of yours.”

Gideon didn’t hear any of it after the part about the lantern. “The basement? So the floor held? Is the Fiddlehead intact?”

“The floor held. Your printing apparatus is so much scrap metal, I’m afraid, but as for the Fiddlehead, I do not know. Ephraim couldn’t say. There was a great deal of debris, and dust, and smoke too, I think. There was a small fire, but it was quickly brought under control.”

“But there’s a chance…?”

“There’s always a chance.” He reached the library and maneuvered the chair through its doorway. “But we won’t know anything until morning, so let’s not worry about what we cannot change. For now, I want you to show me what you were able to save. And then, of course, you must tell me what it means.”

President Ulysses S. Grant shook his head and watched his watery reflection quiver in the glass of Kentucky whiskey. He had better beverages on hand—more expensive beverages, at least—but he picked one of his finer bourbons for the other man, who barely sipped it. What a waste. He should’ve kept it for himself.
