"It's heavy!" she said indignantly. It all looked so easy in the pictures in the illustrated papers.

"This was the lightest one I could find," said Geoff, leveling the pistol with one hand as though it weighed no more than a lady's fan.

"Show-off," said Letty.

Geoff looked smug.

"You want to grasp the stock with both hands to distribute the weight," he said.

He handed the gun back to her, watching critically as she tried again. Letty's arms felt stiff and awkward in the unaccustomed pose.

"Bend your elbows a bit," Geoff suggested.

Letty's arms shot back into an immediate right angle, one elbow catching Geoff in the stomach.

Geoff winced. "Not quite that much."

Easing closer, he reached around her, rearranging her hands on the stock, one slightly above the other.

"Do you feel the difference?" he asked, jiggling the barrel slightly to make her flex her arms.

"Mm-hmm." Letty's mind, admittedly, wasn't entirely on the pistol. A large part of it had wandered off along far more attractive byways having to do with the pleasant scent of Geoff's cologne, and the intriguing way his muscles moved beneath the fitted seams of his coat as he rearranged her hands on the stock.

"Now sight along the barrel." Letty lifted the pistol, and Geoff's arms went with her. She could feel his cheek brush hers as he leaned closer to inspect her aim. "And pretend to aim."

"Like this?" Letty glanced up over her shoulder.

Geoff wasn't looking at the pistol, or the imaginary target.

"Exactly like that."

Letty forgot that she was holding a heavy pistol; she forgot that her neck was twisted at an odd angle, and that she had a blister on the back of one heel.

Geoff's hands tangled in her hair, pulling her face to his for a quick, hard kiss that sent Letty's ears ringing.

The pistol dropped forgotten from her hands, landing with a thud on the floor of his carriage. In some musty corner of her mind, Letty dimly realized that it was a very good thing that the pistol had not been loaded.

Geoff drew back, his hands possessively cupping her shoulders, and stared down into her face. A slight furrow formed above his nose, and his eyes scanned hers as though he were reading a book—a book in a foreign language without a convenient translation at hand.

Letty stared right back, silently willing questions at him.

She wanted to know whether she was more than a responsibility to him. Whether, when he kissed her, he saw her—or her sister. Whether they would go on like this upon their return to England, or whether all their hard-won intimacy would dissolve as soon as they set foot on English soil, like Shakespeare's insubstantial pageants, or fairy gold smuggled into the mortal world only to turn to ash in the harsh light of day.

The door was already open, the steps down, the coachman waiting.

Leaning over, Geoff restored her fallen pistol to her, stock first, putting into the gesture what he hadn't said in words. It smacked of respect—and farewell.

"Be careful," he said simply.

And that was all.

The carriage waited until Letty had mounted the steps to the front door before trundling away down the street.

Letty stood, one hand on the knocker, watching it go, wishing she had said something else. But what? "Be careful?" There was something rather ridiculous about her telling Geoff to be careful, an amateur advising a master. Besides, it was a very poor substitute for what she really wanted to say.

"Be careful" was no substitute for "I love you."

Only one extra word, but as impossible to frame as a word-perfect recitation of the entirety of a Homeric epic. She couldn't declare her love—not only did her pride protest at the notion, but it seemed a hideous sort of imposition to thrust her love unasked on someone who couldn't feel the same way about her. How could he, when he was in love with her sister? It was as ridiculous as a Shakespeare comedy, everyone enamored of the wrong person.

And there was nothing she could do about it. Nothing, except to go on, in a staid and sensible manner, taking what pleasure she could from their companionship and camaraderie.

Much like "be careful," camaraderie made a very poor substitute for love.

"Why didn't you knock?" A pale hand reached out and whisked Letty through the door, putting a pointed period to her unproductive reverie.

"Let's get you costumed, shall we?" said Jane.

Two painful hours later, Letty stood outside Lord Vaughn's Dublin residence, tugging at her cravat.

Like the other great houses that ranged around St. Stephen's Green, Vaughn's Dublin residence was an immense edifice of stone that shone whitely in the sun, new enough that soot had not yet dimmed the luster of the facade. It might not be quite so large as the neighboring Clanwilliam House, or the Whaley mansion, but it would have made at least ten of the little brick house on Henrietta Street.

Letty wondered how Geoff was faring and whether Miss Gwen was as adept with explosive devices as she seemed to think. Sometime after six, he had said, since Emmet was supposed to be dining out, along with his senior staff, at a house in Kilmacud. They would wait till the house was largely empty, and then slip in and detonate the rockets. All perfectly simple. Unless it wasn't.

Letty went back to abusing her cravat.

"Don't fuss with it," said Jane, managing her own hat and cane with the air of one born to them. Her stride was authoritative, her demeanor lordly, and her shirt points would have made Brummell choke with envy. In short, she was the very image of a pink of the ton, setting out for a late-afternoon stroll prior to the evening's dissipations.

Letty glanced down at her own pantaloons. Brummell might choke, but it would be with horror, not envy. Her short, plump figure took to men's fashion about as well as Miss Gwen to humility. Her hips might be suited marvelously well to childbearing but they did nothing for the fit of her pantaloons. Her coat, cut fashionably short at waist and hip before extending behind, did little to cloak the problem. As for other unmanly protuberances, Jane had used lengths of linen to flatten her breasts and thicken her waist, lending Letty's upper half the appearance of an animated barrel of ale.

Beneath her shirt, waistcoat, and coat, she could feel the binding rubbing uncomfortably against her chest, sticky with perspiration. Although the day was mild for mid-July, Letty sweltered beneath her unaccustomed layers and thought longingly of her wardrobe full of light muslin gowns and soft kid half-boots. The stiff leather boots Jane had forced onto her legs cramped her calves and bit into the skin just above her knee every time she ventured a step.

No wonder so many gentlemen preferred to pose nonchalantly against the mantelpiece if it was this painful to move.

"Just keep your chin down," Jane advised, fluffing up Letty's cravat and straightening her shirt points. "And if anyone speaks to you, grunt."

"Grunt?"

"Like this." Jane produced a noise straight from the diaphragm, somewhere between a grumble and a growl. "It is the common masculine coin of communication."

Attempting to emulate her, Letty managed something between a squeak and a cough.

Jane sighed. "Just keep your chin down," she repeated.

"Mmph," said Letty, surreptitiously rubbing her side, where the binding was biting into her flesh.

"Not quite," said Jane, "but an improvement. A marked improvement."

Rolling her eyes, Letty clambered stiff-legged up the front steps after her, wondering how she got herself into these things. Hers was an ensemble better suited to storming a castle than a peaceful afternoon call. In addition to the boots, binding, and shirt points so starched they could be used to patch the roof, the gun tucked into her waistcoat knocked against her ribs as she moved, and the vial of potion formed a lump just inside her sleeve. The paper of pins and paperweight had remained behind, but the tin whistle was attached to her watch chain and the point of the embroidery scissors teased her palm. Fortunately, the formfitting nature of her pantaloons didn't allow for a knife strapped to her thigh, or she was sure Jane would have handed her one of those, too.

Letty was only surprised that no one had given her a small cannon to take along, just in case. She could have disguised it as a dog and wheeled it on a leash.

At the top of the steps, Jane took the knocker and let it fall with an emphatic rattle. Through the plate glass windows on either side, Letty couldn't discern the slightest sign of movement. In a house of such size, there ought to be a footman watching for visitors, ready to pop open the door. The echoes of the knock faded off across the green, unmatched by any answering noise from within.

Frowning, Jane pushed gently against the door with the head of her walking stick. The door fell easily open, revealing a polished expanse of white marble floor, and a staircase that seemed to stretch up forever, patterned on the underside with white stucco-work on a pale blue background. Following Jane, Letty ventured into the vast hall, feeling suddenly chilled. It wasn't just the eerie silence; it was the celestial cool of the endless motif of pale blue and white, like Olympus in the midst of a frost. The walls and ceiling had all been tinted the same pale blue, frosted with a design of urns and stylized acanthus leaves. The marble floor gleamed as pristinely pale as an untrodden field of snow.

"This is most unusual," murmured Jane.

Letty noticed that Jane readjusted her grip on her cane as she prowled across the hall, every step a measured act.
