Even with the dim morning light softening her image, Ada regretted peering into the mirror.

The tousled mess of hair she could fix, but nothing would erase the dark circles beneath her eyes or the waxen hue to her skin.

Waking up a dead woman was not conducive to a radiant glow.

She shivered. None of the lavish decor—not the papered walls nor the gilt furniture—could make the room less dark, less cold, less unappealing. Had anyone ever lived in the room? Ada doubted it. Designed and decorated to within an inch of its life, the boudoir resembled a stage set more than a living, breathing part of a home. The high ceiling dwarfed her, making her look even more vulnerable than she felt, standing before the mirror in nothing but her chemise.

That at least she could remedy.

She laid out her things, sparing a moment to regret that she’d never considered spending more time and effort purchasing prettier undergarments.

Everything down to her drawers was as plain as could be. She fingered the simple lace edging the legs of her drawers. Bold, sensual women had embroidered linens. Embroidered, ruffled, ribboned underthings that made a man want to unwrap them, like Christmas candy.

As if she had the slightest intention of being any man’s sweet. Although, if she were honest, she wouldn’t mind Edison tasting her, kissing her as thoroughly as he’d done in her lab.

She grabbed her drawers and pulled them on, forcing herself to think about the relationship of osmotic pressure to temperature. A more thorough understanding would help her regulate the batteries’ energy flow.

She managed to keep her mind off of men and kissing for at least an entire minute. By now, her fingers were numb with cold, making it hard to fasten the hooks down the front of her corset.

A small, scratching sound caught her ear, making her stomach clench.

Too loud, too quick for a mouse. Not loud or rhythmic enough for tree branches scraping the house, she’d heard it intermittently all night. Now it sounded as if it were coming from the room directly below.

She hurried into her best navy day dress—the only one, really, that didn’t have any chemical burns at the hem. Halfway done buttoning up the front of her bodice, Ada shivered and tried to throw off her anxiety.

The deserted manse was getting to her. The empty hallways, the forsaken chambers, it was unnatural for a house not to have the beating heart of a home.

It was probably nothing more than Edison puttering about. He was most likely in the kitchen making a meal for himself from the bread and cheese he’d bought last night. Her stomach growled. She twisted her hair up into a tight bun and headed down the stairs.

Time to see about turning her life back right side up.

Edison was indeed munching on bread and cheese, though in contrast to her own appearance, he appeared as fresh and rested as his rumpled clothing would allow. And he’d made toast. From the looks of things, he’d even managed to locate some tea.

The tangy scent revived her spirits.

“Good morning.” He filled a mug and slid it across the table. When he finally looked up at her, he gave a start. “You don’t look well.”

Ada fought the urge to run back upstairs.

Edison winced. “I put that poorly. I only meant you look done in. Didn’t sleep well?”

“Of course I didn’t sleep well.” She grabbed the mug and moved to the far end of the table. “It’s not every day a woman wakes up dead. Forgive me if I’m having trouble adjusting.”

He, naturally, looked wonderful. Caramel-colored eyes bright, hair delightfully tousled, he looked as if he’d had a glorious rest.

Ada folded her hands around the warm mug. His competent, self-assured countenance grated. His every calm, powerful movement made her want to snarl.

She took a long gulp of tea. What was happening to her? She was never irritated. She was thoughtful, rational, scientifically-minded. She should be thrilled to have someone so energetic and capable taking on the mess.

But envy was an odd poison. She ached to feel competent, as if there were nothing she couldn’t fix, as if there were no trouble so big she couldn’t conquer it.

Eyes on his own food, Edison slid a plate of toast down to her end of the table. She snapped it up, biting into a stale slice as she tried to push through the emotions clouding her reason.

The cupboard beneath the sink drew her gaze. Edison had hidden her battery in the slop pail beneath a pile of rags. It was as safe as they were.

The thought brought little comfort.

Someone wanted her invention so badly they were willing to kill for it. Someone who knew it existed. Someone who could pass it off as their own creation.

Someone who had intimate knowledge of her movements.

Ada dropped her toast. “Who could have known when the Navy men were to collect me?”

“Exactly what I was wondering,” Edison replied around a mouthful of bread. “Couldn’t be a long list.”

She swirled the tea around in her mug. “Admiral Helmsley, of course, and Stanton. They’re of no consequence.”

“Why not?” Edison frowned. “They’re at the top of my list.”

“An Admiral? The Director of Naval Construction?” Ada snorted. “I think not. Nor Stanton. He’s been a dear friend of the family for forty years.”

Edison was shaking his head before she even finished. “There’s no accounting for greed. Your breakthrough’s worth a fortune to the right person.” He looked her in the eye. “A fortune and a mountain of accolades. Money and fame?” He shrugged. “Not many men that wouldn’t tempt.”

“Men like Stanton and the Admiral.” She clutched her mug. “They already have both.”

“Some men never have enough.”

“And some men wish for none. That’s an illogical argument.”

He nodded, considering. “I’ll concede that, for now.”

“What about Ravensworth?” she asked. “He’s only a captain. Money might tempt him.”

Edison gave her a cautious look. “Same for your household staff.”

Too true.

Ada set down her toast. “How awful. There’s no one to trust.”

“Remember that. Suspicion'll keep you safe.”

She stared down at the dark wood of the tabletop, her mood weighed down by frustration. “Our list is growing by the second. Where do we start?”

“The cottage. Someone leased it.”

“Or knew it was unoccupied.”

“Excellent point. Worth pursuing in either case.” He bit his lip and stared up at the ceiling. “My contact at the Yard should have that information. He can—”

“Shhh.” Ada interrupted. “Did you hear that?” A muffled thud, followed by lighter, scrabbling sounds.

“Rats.” Edison shrugged. “Not surprising. Place has been vacant for months.”

Ada shivered.

A sharp bang echoed down the hallway. Even Edison froze.

Ada raised her eyebrows. “Fearsomely large rats.”

“Could be squirrels.” He brushed crumbs off of his shirtfront, but the casual movement didn’t fool her. He was listening hard now. “This morning we need to see my associate at Scotland Yard. There’s that business of your kidnappers to sort out.”

“How will we find out about the—?"

A loud crash, like books thudding to the floor killed off the rest of her thought.

“Not rats.” Edison jumped up. “Stay here.” He grabbed a good-sized frying pan from the pot rack over the stove and bolted toward the front of the house.

* * *

Edison’s quick thinking had her at a disadvantage. Her brain was still thick with lack of sleep, but her heart raced. She couldn’t sit in the empty kitchen waiting for God-knew-what to bolt through the door. The very thought made her skin crawl.

She needed a weapon.

He’d taken the largest pan. She scanned the room, dismissing the small pairing knife and the tea mugs. The trim saucier with the filigree handle would have to suffice. Ada grabbed it from the hook and chased after him.

He was inching silently toward the front parlor. She tiptoed behind him, the only sound now the rustling of her skirts.

Edison shot her a meaningful glare, which she ignored. The great huff of air he expelled signaled his displeasure with her inability to follow orders.

They crept down the hallway until they came to the first doorway. Edison waved a hand behind him, signaling for her to stop.

She raised the delicate pan high overhead. Edison peered into the first room, then straightened and shook his head. He pointed at the room across the hall.

Nothing in the front parlor, either.

Frying pan at the ready, Edison appeared to be considering the stairway.

The air hung thick and still, as if the house itself didn’t dare exhale. He started up toward the second floor. Careful to pick her skirts up high, Ada stayed right on his heels.

Just as they reached the landing, a dark figure streaked toward the back of the house.

“Got him.” Edison gave chase.

Skirts billowing about her ankles, Ada struggled to keep up. By the time she clattered down the servants’ stairs, her lungs were on fire.

She reached the kitchen just in time to see the dark figure snatch the last of the bread off of the table and sprint out the back door. He was smaller than he seemed upstairs in the dark. And she hadn’t noticed the rucksack slung across his back.

Before Edison could reach him, the slight figure disappeared over the back wall.

Edison latched the door, then ambled back into the kitchen. He stared down at crumbs strewn across the empty table. “I wanted that.”

A weight pressed down on her chest, as if pressing the breath out of her. “Do you think he followed us?”

“No.” Edison headed toward the hallway. “He’s just a street urchin. Had a warm place to bed down until we showed up.”

She prayed he was right. The alternative terrified her.

“If we’d been followed, they would have struck while we were sleeping,” Edison added over his shoulder.

How comforting.

He dove into the library. “He’s been staying here. For quite a while.” He pointed to a chaise in the corner, piled high with blankets. Then he turned to frown at her. “Check your purse.”

“We’ve been here all morning. He wouldn’t be so bold.”

“Care to wager on that?”

Ada ran back up to the dank boudoir. Her purse lay open on the floor below the chest where she’d set it last night. When she picked it up, her stomach churned. Empty. Her change purse, her pencil case, even her silver container of calling cards.

The boy had taken it all.

Tears pricked at the backs of her eyes. Silly tears, for her silly card container. In the scheme of things, it mattered not a whit, but she loved that thing. Harrison had presented it to her after her induction into the Chemical Scientists’ Society.

She stared down into the empty bag.

Edison stepped into the room and set a hand on her shoulder. “Sorry about that. Boys like that’ll do anything to survive.”

If one could call bedding down in a deserted mansion without heat or food or companionship surviving. The sad little pile of blankets in the library tugged at her heart.

Suddenly her loss seemed insignificant. “Do you think he’ll return?”

Edison nodded. “He’ll watch the house. Once he’s convinced we’ve scarpered, he’ll be back.”

Absurdly, the thought reassured her. He might be a thief, but the slight build and the youthful energy suggested he was young. And he couldn’t have chosen a life on the streets.

Edison closed in on her. “Are you all right?”

“Of course,” she answered automatically, although the sharp lump growing in her throat suggested otherwise.

She squeezed her eyes shut, trying to prevent the tears from falling.

But then he set his hands on her shoulders, and the dam burst. Ada sucked in a shuddering breath as tears spilled down her cheeks.

“Don’t believe I am,” she managed to mumble before her shoulders started shaking.

Edison wrapped his arms around her and pulled her close. At first she stiffened, resisting the contact, but something inside her broke, and she sagged against him, nestling into his arms.

He squeezed her tight and murmured softly at her temple. “We’ll manage this. I’ve been through worse.”

Ada nodded. The sobs were subsiding. His heart beat strong and steady beneath her cheek. She sighed. “Do you think he’s cold?”

“Who?”

“The boy. Do you think he’s got a warm enough coat?”

His chuckle rumbled through her. “We’ll make certain of it. We need clothes anyway. We’ll pick up a few things for the lad, leave them where he’ll be sure to spot them.”

“Thank you.” Ada pressed her forehead against his chest. Her eyes must be red rimmed now, and swollen. To say nothing of her nose and her tear-stained cheeks.

She sighed and pulled slowly out of his arms. “It seems I require a handkerchief.”

With a flourish good enough for a magician, Edison pulled a white square from his pocket and handed it to her. “Milady.”

Besides drying her tears, the handkerchief provided a good excuse to turn away. Never had she felt so vulnerable. So adrift.

She had no rulebook for this strange world.

Edison would be an exceptional guide, if she’d allow him to lead.

Ada sniffed away the last of her tears. “Well then, Mr. Sweet, what’s our first course of action?”
