Of course, if I didn’t act fast, he might easily gain a stone or two; Mrs. Bug had set herself to outdo Lord John’s Indian cook (of whom we had heard much), and to this end was shoveling eggs, onions, venison, and a slice of leftover pork pie onto Bobby’s plate, to say nothing of the basket of fragrant muffins already in front of him.
Lizzie, seated beside me, took one of these and spread it with butter. I noted with approval that she, too, was looking healthier, delicately flushed—though I must remember to take a sample to check the malarial parasites in her blood. That would be an excellent thing to do while she was out. No way of getting an exact weight for her, unfortunately—but she couldn’t weigh more than seven stone, small and light-boned as she was.
Now, Bree and Roger at the other end of the scale … Roger had to weigh at least a hundred and eighty-five; Bree probably one-fifty. I took a muffin myself, thinking how best to bring up my plan. Roger would do it if I asked, of course, but Bree … I’d have to be careful there. She’d had her tonsils out under ether at the age of ten, and hadn’t liked the experience. If she found out what I was up to and began expressing her opinions freely, she might arouse alarm in the rest of my guinea pigs.
Enthused by my success at making ether, I had seriously underestimated the difficulty of inducing anyone to let me use it on them. Mr. Christie might well be an awkward bugger, as Jamie on occasion called him—but he was not alone in his resistance to the notion of being rendered suddenly unconscious.
I would have thought that the appeal of painlessness was universal—but not to people who had never experienced it. They had no context in which to place such a notion, and while they presumably didn’t all think ether was a Papist plot, they did view an offer to remove pain from them as being in some way contrary to the divine vision of the universe.
Bobby and Lizzie, though, were sufficiently under my sway that I was fairly sure I could coax—or bully—them into a brief trial. If they then reported the experience in a positive light … but improved public relations was only the half of it.
The real necessity was to try my ether out on a variety of subjects, taking careful note of the results. The scare of Henri-Christian’s birth had shown me how woefully unprepared I was. I needed to have some idea of how much to administer per unit of body weight, how long such-and-such a dose might last, and how deep the resulting stupor might be. The last thing I wanted was to be up to my elbows in someone’s abdomen, only to have them come suddenly round with a shriek.
“You’re doing it again, mum.” Bobby’s brow creased as he chewed slowly, eyes narrowed at me.
“What? What am I doing?” I feigned innocence, helping myself to a bit of the pork pie.
“Watching me. Same as a sparrer hawk watches a mouse, just afore she stoops. I’n’t she?” he appealed to Lizzie.
“Aye, she is,” Lizzie agreed, dimpling at me. “But it’s only her way, ken. Ye’d make a big mouse, Bobby.” Being Scottish, she pronounced it “moose,” which made Bobby laugh and choke over his muffin.
Mrs. Bug paused to pound him helpfully on the back, leaving him purple and gasping.
“Well, wha’s amiss wi’ him, then?” she asked, coming round to squint critically at Bobby’s face. “Ye’ve no got the shits again, have ye, lad?”
“Again?” I said.
“Oh, no, mum,” he croaked. “Perish the thought! ’Twas only eating green apples, the once.” He choked, coughed, and sat up straight, clearing his throat.
“Can we please not talk about me bowels, mum?” he asked plaintively. “Not over breakfast, at least?”
I could feel Lizzie vibrating with amusement next to me, but she kept her eyes demurely on her plate, not to embarrass him further.
“Certainly,” I said, smiling. “I hope you’ll be staying for a few days, Bobby?” He’d come the day before, bearing the usual assortment of letters and newspapers from Lord John—along with a package containing a marvelous present for Jemmy: a musical jack-in-the-box, sent specially from London by the good offices of Lord John’s son, Willie.
“Oh, I s’all, mum, yes,” he assured me, mouth full of muffin. “His Lordship said I was to see if Mr. Fraser had a letter for me to carry back, so I must wait for him, mustn’t I?”
“Of course.” Jamie and Ian had gone to the Cherokee a week before; it was likely to be another week before they returned. Plenty of time to make my experiments.
“Is there anything I might do, mum, in the way of service to you?” Bobby asked. “Seeing as I’m here, I mean, and Mr. Fraser and Mr. Ian not.” There was a small tone of satisfaction in this; he got on all right with Ian, but there was no doubt that he preferred to have Lizzie’s attention to himself.
“Why, yes,” I said, scooping up a bit of porridge. “Now that you mention it, Bobby …”
By the time I had finished explaining, Bobby still looked healthy, but a good deal less in bloom.
“Put me asleep,” he repeated uncertainly. He glanced at Lizzie, who looked a little uncertain, too, but who was much too used to being told to do unreasonable things to protest.
“You’ll only be asleep for a moment,” I assured him. “Likely you won’t even notice.”
His face expressed considerable skepticism, and I could see him shifting about for some excuse. I’d foreseen that ploy, though, and now played my trump card.
“It’s not only me needing to judge the dose,” I said. “I can’t operate on someone and give the ether at the same time—or not easily. Malva Christie will be assisting me; she’ll need the practice.”
“Oh,” Bobby said thoughtfully. “Miss Christie.” A sort of soft, dreamy expression spread across his face. “Well. I s’ouldn’t want to put Miss Christie out, of course.”
Lizzie made one of those economical Scottish noises in the back of her throat, managing to convey scorn, derision, and abiding disapproval in the space of two glottal syllables.
Bobby looked up in inquiry, a bit of pie poised on his fork.
“Did you say something?”
“Who, me?” she said. “O’ course not.” She got up abruptly and, carrying her apron before her, neatly shook crumbs into the fire, and turned to me.
“When d’ye mean to do it?” she demanded, adding a belated, “ma’am.”
“Tomorrow morning,” I said. “It needs to be done on an empty stomach, so we’ll do it first thing, before breakfast.”
“Fine!” she said, and stamped out.
Bobby blinked after her, then turned to me, bewildered.
“Did I say something?”
Mrs. Bug’s eye met mine in perfect understanding.
“Not a thing, lad,” she said, depositing a fresh spatulaful of scrambled eggs onto his plate. “Eat up. Ye’ll need your strength.”

BRIANNA, CLEVER WITH her hands, had made the mask to my specifications, woven of oak splits. It was simple enough, a sort of double cage, hinged so that the two halves of it swung apart for the insertion of a thick layer of cotton wool between them, and then back together, the whole thing shaped to fit like a catcher’s mask over the patient’s nose and mouth.
“Put enough ether on to dampen the cotton wool all through,” I instructed Malva. “We’ll want it to take effect quickly.”
“Aye, ma’am. Oh, it does smell queer, doesn’t it?” She sniffed cautiously, face turned half away as she dripped ether onto the mask.
“Yes. Do be careful not to breathe too much of it yourself,” I said. “We don’t want you falling over in the midst of an operation.”
She laughed, but dutifully held the mask further away.
Lizzie had bravely offered to go first—with the clear intent of deflecting Bobby’s attention from Malva to her. This was working; she lay in a languid pose on the table, cap off, and her soft, pale hair displayed to best advantage on the pillow. Bobby sat beside her, earnestly holding her hand.
“All right, then.” I had a tiny minute-glass to hand, the best I could do by way of keeping accurate time. “Put it gently over her face. Lizzie, just breathe deeply, and count with me, one … two … goodness, that didn’t take long, did it?”
