Don't ask me, ask Jillian. She made it up.

Stage One: Colin froze with one hand on the mobile. Stage Two: Eyes narrowing, Colin leaned forward, face arranged in just the right blend of curiosity and confusion. Stage Three:…

I didn't wait to see Colin go through Stage Three. I hastily wrenched my gaze back to Jay.

"Tofu turkey? Really?" I said breathlessly.

I put an extra few watts into my smile at Jay, just because. It was a sickening display. Grandma would have been so proud.

"Only that one year," said Jay, clearly anxious lest I think them impossibly passй on the Thanksgiving menu front. "And it was just because my brother's girlfriend doesn't eat meat." He made it sound like a personal failing.

"What did it taste like?"

"Turkey," said Jay.

On that scintillating note, a shadow fell across our table.

"Hi," Colin said.

He smelled of the outdoors, of cold, clean air, and falling leaves, and long, open stretches of parkland, a world away from the muggy heat of the Indian restaurant. His pale green shirt was open slightly at the collar, lending a greenish cast to his hazel eyes. His skin looked tanner than the last time I had seen him, the healthy brown of the dedicated outdoorsman, although that might only have been in contrast to Jay's office-park pallor.

There's a Christina Rosetti poem that begins, "The birthday of my life is come / My love is come to me." Well, I couldn't claim—at least not with a straight face—that my heart was like the singing bird that perched upon the watered shoot. And I think Rosetti was talking about Christ, or something equally allegorical and noncarnal. But my spirits did float up like leaves eddying in playful circles in an autumn breeze.

Up—and down. All those ridiculous conflicting emotions one experiences and would like to pretend one didn't. Ecstatic joy that he had gotten up and walked all the way across the room—to see me! Staggering resentment that he hadn't called. Desperate yearning for some sort of sign, some sort of signal, that he would have liked to have called.

And, topping it all off, extreme personal annoyance for all of the aforementioned emotions. What was I, thirteen?

"Hi," I said.

We stared at each other like idiots.

At least, I was staring like an idiot, desperately trying to think of something neutral to say. "Where have you been?" and "Why the hell haven't you called me?" didn't seem to come under that category. Nor did "Colin, take me away!" Besides, that was supposed to be "Calgon," not "Colin."

"Hi," Jay said loudly, completing the conversational circle. He stuck out a hand. "Jay Watkins."

Colin's hand met his with an audible thump, like two gorillas bumping chests in the forest. "Colin Selwick."

"Oh, right, sorry," I said incoherently, shoving the hair back out of my face. It promptly flopped back again. Chin-length hair and a side part do not a convenient combination make. "Colin, Jay. Jay, Colin."

The introductions having been completed—twice—I belatedly remembered my manners.

"How is your aunt?" For Jay's benefit, I added, "Colin's aunt was kind enough to help me out with my research."

"Wreaking her usual havoc," Colin said fondly. "You should ring her. I'm sure she'll want to hear how you're getting on."

"I'll do that." All the excited flutters leached out of me, like air from a burst balloon. Of course, that was why Colin had come over. As a courtesy on behalf of his aunt. A duty visit. That was what the whole thing had been, from the very beginning, and I was an idiot to have ever thought otherwise.

What sort of pathetic creature was I, that I had mistaken plain good manners for romantic interest?

That, by the way, was a rhetorical question. The answer was too grim to contemplate.

I took a bracing sip of my wine. "It's very kind of her to take an interest."

Colin braced both hands against the tabletop, the corners of his eyes crinkling as he leaned forward. "How are you getting on?"

"Very well, actually." I couldn't have him thinking that I was entirely dependent on his family's good graces. "I followed a hunch and came across some great stuff in the BL."

"I didn't realize the BL had anything on the Carnation."

"I don't think they realized either." Flipping back my hair, I grinned up at him. "It's all under 'Alsdale'—whoever entered it into the computer clearly just took the name off the bottom of the letters."

"Alsdale? That doesn't sound familiar."

He seemed so genuinely interested that I couldn't resist. Besides, I'd been dying to tell someone. Alex was busy, Pammy couldn't care less, and my adviser responded to e-mails about once every three months. If I was lucky.

"Remember Mary Alsworthy?"

"Vaguely," said Colin cautiously. "It's been years since I read through those papers."

"Her sister Letty married Geoffrey Pinchingdale-Snipe. He went off to Ireland in 1803—"

"That much I did know."

"—and she followed after him, under the name Alsdale."

"So you followed 'Alsworthy' to 'Alsdale'?"

"Mm-hmm," I said smugly. "And it gets even better. Guess who else was there?"

Jay wanted to play, too. "The Scarlet Pumpernickel?"

Colin fell pray to a sudden coughing fit.

"Close," I said, bracing one elbow against the table and leaning encouragingly toward Jay. Even aside from Colin's coughing fit, I did feel a little bad about Jay. After all, it must be very tedious for him to be stuck listening to a detailed discussion on an esoteric topic he knew nothing about—much like I had felt when he had been going on about his three previous companies.

Besides, being on a date with Jay was clear proof that I had never, ever cherished tender notions regarding Colin. And I certainly hadn't checked my phone every five minutes for the past ten days waiting for him to call.

Guilt—and less laudable motives—inspired me to bestow a warm smile in Jay's direction. "It wasn't the Pimpernel, but it was another spy with a flowery name."

Jay shook his head, struggling for words.

"I can't believe you're spending seven years of your life on spies named after flowers."

I abruptly ceased feeling bad about Jay.

"If all of this has been sitting at the BL all this time," said Colin, crossing his arms across his chest, "why hasn't anyone come across it before?"

I shook my head. "I'm not explaining it well, am I? First, it's in one of those jumble folios. Someone just tossed the contents of their attic into a notebook and sent it off to the BL. I don't think anyone's opened it since it got there in 1902. On top of that, Letty doesn't use proper names anywhere. I mean, from time to time she'll throw in a reference to the Carnation or the Tulip, but most of the time you have to work by inference. Everyone—and I do mean everyone—seems to be traveling under an assumed name. The only reason I was able to figure out who was who was because I was looking for it. I knew Letty's relationship to Geoffrey Pinchingdale-Snipe, and I knew that if there was a Jane operating in concert with a Geoffrey, it was probably the Jane."

"So you followed Geoffrey to Letty, and Letty to Jane." The words were simple enough, but the admiring look that accompanied them made me want to wriggle and thump my tail like a happy puppy dog.

"Basically. To anyone reading the letters cold, it would all just sound like pointless gossip—he-said, she-said sort of stuff about a bunch of historically unimportant people. You have to read pretty far along before you even get to the first Pink Carnation mention." I tried to look modest and missed by about a mile. "Guess what Jane's alias was?"

"The Scarlet Pumpernickel?"

I bit my lip on a grin and cast him a mock reproachful look. My restraint was entirely wasted on Jay, who was surreptitiously checking his BlackBerry, entirely unaware that he was being mocked. "Not even close. She traveled as a Miss Gilly Fairley."

"Gilly…for gillyflower?"

The lad was quick.

"Exactly." I beamed.

Jay slid his BlackBerry back under the table. "Gillyflower?"

"It's another name for a carnation," I explained.

"As in pink," added Colin.

"Oh, right." Jay took a long pull of his beer.

"Are you a historian?" asked Colin politely. A little too politely.

With the conversation directed back where it belonged—him—Jay perked up. "No. I help technological service providers actualize their human resource needs."

I took a peek at Colin, but he had his poker face down pat. "A necessary cog in the great wheel of social progress," he said solemnly.

Damn. Jay was rapidly losing value as a face-saving device. Something had to be done, and quickly.

"Jay made some great suggestions about my dissertation earlier!" I chimed in, like a one-woman cheerleading squad.

Across the table, Jay preened.

"Really?" Colin looked expectantly at Jay.

"Yes! I mean, yes. Jay, um, reminded me that it's all too easy to assume an Anglocentric viewpoint while working with a source base composed primarily of the epistolary product of a privileged segment of English society. He suggested that it might be a useful corrective to factor in the social, economic, and political grievances of the oppressed Irish underclass." I took a healthy swig of my wine. "In the interest of scholarly accuracy, of course."

Jay looked much as I must have when he started going on about actualizing technological potentialities. Ha! I could speak gibberish, too, when I wanted to. No field is without its own useful circumlocutions—which roughly translates as "important-sounding babble."
