An anemic red arrow pointed visitors down a narrow flight of stairs with shiny reflective tape beginning to peel back from the treads. Clutching the warped handrail, I picked my way carefully down and came straight up against — the bathrooms. The little stick figures were unmistakable.

Next to them, however, a plain white door had been marked with the word REFERENCE. It was just the tiniest bit ajar, presumably for ventilation rather than hospitality. I pushed the door the rest of the way open and made my way in, the heels of my boots slapping hollowly across the linoleum floor.

In contrast to all the gilt and rosewood upstairs, the reference room wasn't a very impressive setup. The room was small and square, furnished with two rickety aluminum folding tables, each supplied with four equally rickety folding chairs with hard plastic seats. Padding might have encouraged people to linger. At the far end of the room, a small counter, not unlike those in drugstores, separated the reference room from the archives beyond. Through the gap I caught a tantalizing glimpse of utilitarian metal shelves piled with a variety of acid-free boxes and big black binders.

At the desk, a man in a hot pink T-shirt guarded the gap. I use the word "guarded" loosely. He was so deeply absorbed in whatever he was reading that I could have vaulted over the desk without his noticing me. The thought was tempting, but that kindergarten training dies hard. I didn't vault. Instead I coughed. When that didn't work, I coughed again. Loudly. I was afraid I was going to have to resort to more drastic measures — like sneezing — but the third cough finally broke through his literary absorption. As he hoisted himself up, I took a peek at his reading material. It was a copy of Hello! magazine, open to a fine showing of airbrushed celebrities.

Somehow, I didn't think this was the archivist. In fact, I had a pretty shrewd guess as to who he was.

"I believe we spoke on the phone," I said.

Clearly, he also remembered our conversation fondly. His face went from lascivious to hostile in the space of a second. "Oh. You."

So much for being a goodwill ambassador for America, or whatever else it is that the Fulbright people expect you to do. Fortunately, my grant was a Clive fellowship, not a Fulbright, so I was off the hook. As far as I could tell, Mr. Clive had harbored no pretensions about his grantees fostering international amity.

That being the case, I felt no guilt at all about saying crisply, "I'm here to see the papers of Sebastian, Lord Vaughn."

The boy gave me a look as though to say, "You would." Levering himself up with obvious effort, he trudged wearily off into the blazing desert sands, five hundred miles across rugged terrain, to the metal shelves right behind the desk. There, he made a great show of studying the labels on the binders.

"That's Vaughn, v-a-u-g-h-n," I said helpfully. "Sebastian, Lord Vaughn."

"Which one?" asked Pink Shirt dourly.

It had never occurred to me that there might be other Sebastian, Lord Vaughns floating around. "There's more than one?"

"1768 or 1903?"

It was a bit like ordering a hamburger. "1768."

After a moment, his head popped back around again. "Do you want the 1790 box, the 1800 box, or" — his head ducked back down for a moment — "the everything else box?"

Next, he was going to ask me if I wanted fries with that. I made my choice, and the 1800 box was duly shoved into my hands. The tape on one end bore a label that descriptively stated, "Seb'n, Ld. Vn., Misc. Docs. 1800–1810."

I began to wonder if the archivist actually existed, or if they just pretended they had one for the sake of show. Not only was that one of the less convincing classificatory systems I had ever encountered, there had been no effort made to put the contents of the box in any sort of order; small notebooks, loose papers, and packets of letters were all jumbled, one on top of the other. Given that Vaughn had lived well into the reign of Victoria, my hunch was that the everything else box wasn't so-called because there wasn't much there for the next forty years of his life, but simply because no one had gotten around to sorting through it yet.

Settling myself down at the more stable of the two tables, I reached for the first packet in the 1800 box, gingerly unwinding the string that bound the letters. There's nothing like peering into someone else's correspondence. You never know what you might find. Coded messages, plotting skullduggery, passionate letters from a foreign amour, invitations to a late assignation…These turned out to fit none of the categories above. They were all from Vaughn's mother.

What was this with everyone having a mother all of a sudden?

Shoving my hair back behind my ears, I skimmed through the letter on the top of the pile. After one letter, I decided I liked Vaughn's mother. By the end of three, I really liked Vaughn's mother, but reading about Vaughn's spinster cousin Portia who had run off with a footman ("She might at least have picked a handsome one," opined Lady Vaughn) wasn't getting me any nearer to ascertaining the identity of the Black Tulip, so I reluctantly put the pile aside for future perusal and dug back into the box.

I toyed with the notion of Lady Vaughn herself as the Black Tulip, spinning her webs from the safety of Northumberland as she sent out her minions to do her dirty work. Sadly, it didn't seem the least bit probable. From her letters, Lady Vaughn was far too busy bullying the vicar and terrifying her family to be bothered with international espionage. Another great opportunity wasted.

I flipped quickly through the usual detritus of a busy life. There were love letters (using that term broadly); invitations to routs and balls and Venetian breakfasts; an extensive correspondence with his bankers (which generally seemed to boil down to "send more money"), and, at the very bottom of the box, tucked away where one might never have noticed it, a nondescript black book.

It wasn't a little black book in the modern sense. There was no list of addresses, conveniently labeled, MEMBERS OF THE LEAGUE OF THE BLACK TULIP (LONDON BRANCH). But the reality was nearly as good. I had found Lord Vaughn's appointment book. All of Lord Vaughn's movements, recorded in his own hand. His writing was just like his appearance, elegant, but with a sharp edge to it. I paged rapidly through it until I hit 1803, watching the place-names change from the exotic (Messina, Palermo, Lisbon) to the familiar (Hatchards, Angelo's, Manton's). Vaughn, I noted, had had a particularly close and personal relationship with his tailor; he saw him nearly once a week.

I was ruffling lazily through, wondering idly if I could make something out of those tailor appointments (there had, after all, been a round of spies rousted out of a clothiers establishment the year before), when a familiar name struck my eye: Sibley Court.

Sibley Court…I knew I had encountered that name before. After a moment staring into space, it finally clicked. Sibley Court was the family seat of the Viscounts Pinchingdale.

I bolted upright in my uncomfortable chair. Viscount Pinchingdale, at least the Viscount Pinchingdale in possession of the title in 1803, had been second in command of the League of the Purple Gentian, from which he moved on to aiding in the endeavors of the Pink Carnation. He was no fan of Lord Vaughn.

What might the potential Black Tulip be doing at the family seat of a known agent of England?

Well, that was a silly question. Spying, one presumed.

I would never know one way or another unless I read on. The entry was terse, but it was enough for a start. Especially once I recognized the names involved, including that, prominently featured, of Miss Jane Wooliston, otherwise known (although not to many) as the Pink Carnation.

14 Oct., 1803. Sibley Ct., Gloucestershire. Immured in Elizabethan horror in G'shire. Forced to play hunt the slipper with Dorrington and wife. Selwick going on about days of glory in France. Interesting proposition made to me by Miss Wooliston…

October, 1803

Sibley Court, Gloucestershire

Sebastian, Lord Vaughn, stood beside a rusting suit of armor, a dusty glass of claret in hand, wondering for the tenth time what evil demon had possessed him to accept an invitation to the house party at Sibley Court. It had to be a demon; Vaughn held no truck with deities.

The house, which had been closed for well over a decade, was a masterpiece of Elizabethan handicraft — in other words, an offense to anyone with classical sensibilities. Vaughn regarded a series of carved panels with distaste. The repetition of Tudor roses had undoubtedly been intended as a heavy-handed compliment to the monarch. The tapestries were even worse than the paneling, lugubrious depictions of the darker moments of the Old Testament, enlivened only by a rather buxom Eve, who seemed to be juggling her apples rather than eating them.

Sibley Court had slumbered among its memories and dust motes since the death of the current Viscount Pinchingdale's father and had only just been hastily opened for the accommodation of the viscount and his new bride. Vaughn had no doubt that the new viscountess would soon have the ancient flagstones gleaming. She was the managing sort. So far, she had already managed her guests through supper, a game of hunt the slipper, and an abortive attempt at blindman's buff that had come to an abrupt halt when the hoodsman, one Mr. Miles Dorrington, had blundered into a suit of armor under the delusion that it might be his wife, bringing the entire edifice crashing down and nearly decapitating the dowager Lady Pinchingdale in the process.
