“It is the latest thing in London as well, or didn’t you know even that much?” Sophronia was going to run with it. Bumbersnoot, for his part, remained perfectly still, like a good little dog. Although she thought she saw a twinkle of mischief in his jet eyes. She put him carefully under the settee, and then draped a shawl over the edge, as if protecting him from the avarice in the eyes of those around her. It would give Bumbersnoot a chance to explore discreetly.

Sophronia would have wagered her best robe à transformation that Petunia wanted nothing so much at that moment as to go to finishing school herself.

The girls around her murmured in distress as Sophronia began to dress.

“You don’t have to wear that, do you?” said one.

Sophronia had begged an old dress from Sister Mattie. It was black and severe and could be thought a mourning gown, it was so plain. Over the last few weeks she had tailored it into a narrow silhouette, most unfashionable.

“Sophronia, dear, it’s so ugly!” remonstrated Petunia.

Sophronia pulled it on. She looked well in black, and as a young lady with no deaths in the family, she rarely had the opportunity to wear it. It went on easily. Sister Mattie did not employ a lady’s maid, so all of her dresses fastened up the front. But what Sophronia, Dimity, Agatha, and Sidheag had spent their free time doing to that dress was ingenious.

They had cut it in and down at the collar so that Sophronia wore it over a white blouse. Both were low enough, however, to show a goodly amount of cle**age. Sophronia had very nice cle**age and was under orders from Mademoiselle Geraldine to take advantage of it. One never knows when one might need to hide or distract; décolletage is good for both. Hers were nothing on Mademoiselle Geraldine’s own considerable assets, but then, whose were? The bodice was tailored all the way to her waist, nipped in further with a wide, stiff leather belt. The effect was almost like a blacksmith’s apron, giving Sophronia a utilitarian, masculine look. The white underskirt was full enough to disguise the fact that it was actually divided down the middle and could act as trousers if necessary. Over this was draped the skirt of the black gown, split up each side so it looked even more apronlike. To it they had sewn multiple pockets in shades of black and gray, in variable sizes, largest and lightest at the bottom, smallest and darkest near the waist, forming a pattern. In those pockets Sophronia had stashed useful objects. Not that she expected trouble, but she had the pockets so she might as well use them.

“Sophronia, what are you meant to be?” Petunia was disgusted.

Sophronia pulled out her mask; it was an asymmetrical slash of black lace, like a large smudge. “I’m a sootie, of course.”

The young ladies all gasped. Imagine going to a masquerade as something lower class! There was some muttering about the fact that at least Sophronia wouldn’t be competing for masculine attention.

“Well,” sniffed Petunia, “I suppose we should be glad you didn’t actually don masculine attire.”

Sophronia blinked at her. Yes, yes you should. She said, “Oh, dear, do you think this too plain?”

“Of course it’s too plain!”

“I was thinking of your finer feelings, sister dear. I wouldn’t want to distract the gentlemen. After all, I’m not officially out yet. You’re on the market; you should have first crack.”

“Oh, well, that’s very thoughtful, Sophronia.” Petunia fluffed the skirts of her shepherdess outfit, trying not to look pleased by the consideration.

Dimity grinned from behind her mechanical mask.

Sophronia winked at her.

They both knew the truth. The very plainness of Sophronia’s dress would make it stand out in a sea of color. Besides, Sophronia had the figure to carry it off. After a stint at Mademoiselle Geraldine’s, she also had the bearing. Also, the simplicity would make others underestimate her, never a bad thing. Sophronia loved the gown for its practicality and for its nod to her friends belowdecks. Soap would have thought it a great joke. After all, it looked like a feminine version of the apron he wore to shovel coal.

The ball had started, but there was still an hour or more before they could safely go down without being thought desperate. Sophronia and Dimity made their way to the settee corner. Sophronia occupied herself checking the sharpness of her scissors and letter opener and wishing for a bladed fan while relaying softly some of her conversation with Felix in the cart.

Suddenly an excited twittering emanated from the door, opened by a very uncomfortable-looking Pillover. He cleared his throat.

Before he could say anything, Dimity pushed through the crowd to face him. “Pill, you aren’t supposed to be here. We’re dressing!”

Pillover grumbled something unintelligible. Dimity nodded. She replied sharply and then shut the door in his face.

The hubbub died down and the young ladies returned to fixing masks and fussing with hair, now accompanied by discussion of Pillover’s finer points. This startled Sophronia and Dimity—who would have thought he had any? Apparently his complexion was considered lovely, and he was a nice height for dancing, and the sullen glumness came off as deliciously mysterious.

“Don’t you want to cuddle and console him? Poor darling, he looks so unhappy,” said one, pulling on long white gloves.

“I wager he’s had his heart broken,” suggested another. She wore the costume of a Greek goddess—swathes of white silk draped over a turquoise ball gown and large crinoline. She was one of many who had opted for the classics. “I should love to be the one to repair his tortured soul.”

Dimity made her way back to Sophronia, not bothering to advocate for or against her sibling. Pillover would suffer the slings and arrows of willing young ladies without her help. “Pillover needs to talk. Alone. He’s been trying to all along, apparently, but Felix has always been there. I told him to wait in the gazebo. I knew he’d remember it from before.”

The gazebo had been the location of all the fuss with the prototype and Monique the first time Dimity and Pillover had attended a party at the Temminnicks’. It burned down as a result, but Sophronia’s mother had had it rebuilt bigger and better. Sophronia had used the reconstruction to hide her stolen airdinghy. The small aircraft seemed a part of the roof structure, hidden in plain sight like a basket figurehead on top.

Sophronia looked around at the excited young ladies. “We’ll never escape unseen. Too many people at too close quarters.”

Dimity nodded. “I think he mainly needs to talk to you. I’ll create a distraction. If the message was meant for both of us, he’d have told me himself while you were flirting with Felix. It’ll be easier for you to get around with all the borrowed mechanicals. In that outfit you might be taken as staff, so long as you avoid family.”

Sophronia reached below the settee, grabbed Bumbersnoot, and shoved him under the throw rug in one corner of the room with an encouraging “Go ahead.”

Bumbersnoot began to explore, a moving lump under the carpet.

“There’s your distraction. You can keep him safe?”

Dimity smiled. “In this crowd? Of course. Most of them will faint, and the others are silly.”

It was a fair assessment. “Yet you still want to be one of them?”

“It’s not the deceit I object to, Sophronia dear, it’s the danger.”
