I have been slow to write about myself. This is partly because the very existence of this letter proves, well enough, that I live. But it is also because I can hardly bring myself to write about the baby-may God have mercy on his little soul. For by now, he is with the angels in Heaven.

After several false starts my labor began in the evening of the 27th of June, which I think was extremely late-certainly I felt as if I had been pregnant for two years! It was early the next morning that my bag of waters broke and poured out like a flood from a broken dam.*Now things became very busy at the Binnenhof as the apparatus of labor and delivery swung into action. Doctors, nurses, midwives, and clergy were summoned, and every gossip within a radius of five miles went to the highest state of alert.

As you have guessed, the incredibly tedious descriptions of labors and deliveries that follow are nothing but the vessel for this encrypted message. But you should read them anyway because it took me several drafts and a gallon of ink to put into words one one-hundredth of the agony, the endless rioting in my viscera as my body tried to rip itself open. Imagine swallowing a melon-seed, feeling it grow in your belly to full size, and then trying to vomit it up through the same small orifice. Thank God the baby is finally out. But pray for God to help me, for I love him.

Yes, I say “love,” not “loved.” Contrary to what is written in the unencrypted text, the baby lives. But I get ahead of myself.

For reasons that will shortly become obvious, you must destroy this letter.

That is, if I don’t destroy it first by dissolving the words with my tears. Sorry about the unsightly blotching.

To the Dutch and the English, I am the Duchess of Qwghlm. To the French, I am the Countess de la Zeur. But neither a Protestant Duchess nor a French Countess can get away with bearing and rearing a child out of wedlock.

My pregnancy I was able to conceal from all but a few, for once I began to show, I ventured out in public only rarely. For the most part I confined myself to the upper storys of the house of Huygens. So it has been a tedious spring and summer. The Princesses of Ansbach, Eleanor and Caroline, have been staying as honored guests of the Prince of Orange at the Binnenhof, which as you know is separated from the Huygens house by only a short distance. Almost every day they strolled across the square to pay a call on me. Or rather Eleanor strolled, and Caroline sprinted ahead. To give a curious six-year-old the run of such a place, cluttered as it is with Huygens’s clocks, pendulums, lenses, prisms, and other apparatus, is a joy for the little one and a deadly trial for all adults within the sound of her voice. For she can ask a hundred questions about even the least interesting relic that she digs up from some corner. Eleanor, who knows practically nothing of Natural Philosophy, quickly wearied of saying “I don’t know” over and over again, and became reluctant to visit the place. But I had nothing better to do with my time as the baby grew, and was hungry for their company, and so attended closely to Caroline and tried as best I could to give some answer to every one of her questions. Perceiving this, Eleanor got in the habit of withdrawing to a sunny corner to do embroidery or write a letter. Sometimes she would leave Caroline with me and go out riding or attend a soiree. So the arrangement worked out well for all three of us. You mentioned to me, Doctor, that the late Margrave John Frederick, Caroline’s father, had a passion for Natural Philosophy and Technologickal Arts. I can now assure you that Caroline has inherited this trait; or perhaps she has dim memories of her father showing off his fossil collection or his latest pendulum-clock, and so feels some communion with his departed soul when I show her the wonders of Huygens’s house. If so it is a tale that will seem familiar to you, who knew your father only by exploring his library.

Thus Eliza and Caroline. But too Eliza and Eleanor have been talking, late at night, when Caroline is asleep in her bedchamber in the Binnenhof. We have been talking about Dynamics. Not the dynamics of rolling balls on inclined planes, but the dynamics of royal and noble families. She and I are both a little bit like mice scurrying around on a bowling-green, trying not to be crushed by the rolling and colliding balls. We must understand dynamics in order to survive.

Only a few months before I became pregnant, I visited London. I was at Whitehall Palace with Daniel Waterhouse when the son of James II-now Pretender to the throne-was supposedly born. Was Mary of Modena really pregnant, or only stuffing pillows under her dress? If she was pregnant, was it really by the syphilitic King James II, or was a healthy stud brought in to the royal apartments to father a robust heir? Supposing she was really pregnant, did the baby survive childbirth? Or was the babe brought forth from that room really an orphan, smuggled into Whitehall in a warming-pan, and triumphantly brought forth so that the Stuart line could continue to reign over England? In one sense it does not matter, since that king is deposed, and that baby is being reared in Paris. But in another sense it matters very much, for the latest news from across the sea is that the father has taken Derry, and is on the march elsewhere in Ireland, trying to win his kingdom back for his son. All because of what did or did not happen in a certain birthing-room at Whitehall.

But I insult your intelligence by belaboring this point. Have you found any changelings or bastards in Sophie’s line? Probably. Have you made these facts known? Of course not. But burn this anyway, and sift the ashes into that canal you are always writing about, making sure beforehand that there are no ill-tempered gondoliers beneath your window.

As a Christian noblewoman, never married, I could not be pregnant, and could not have a child. Eleanor knew this as well as I. We talked about it for hours and hours as my belly grew larger and larger.

My pregnancy was hardly a secret-various servants and women of the household knew-but I could deny it later. Gossips would know I was lying, but in the end, they are of no account. If, God forbid, the baby was stillborn, or died in infancy, then it would be as if it had never happened. But if the baby throve, then matters would be complicated.

Those complications did not really daunt me. If there was one thing I learned at Versailles, it was that Persons of Quality have as many ways of lying about their affairs, perversions, pregnancies, miscarriages, births, and bastards as sailors have of tying knots. As the months of my pregnancy clunked past, ponderous but inexorable, like one of Huygens’s pendulums, I had some time to consider which lie I would choose to tell when my baby was born.

Early, when my belly was just a bit swollen, I considered giving the baby away. As you know, there are plenty of well-funded “orphanages” where illegitimate children of the Quality are raised. Or if I searched long enough I might find some decent mother and father who were barren, and would be more than happy to welcome a healthy infant into their house.

But on the first day that the baby began to kick inside of me, the idea of giving him away faded to an abstraction, and shortly vanished from my mind.

When I reached my seventh month, Eleanor sent to Eisenach for a certain Frau Heppner. Frau Heppner arrived some weeks later, claiming to be a nurse who would look after Princess Caroline and teach her the German language. And this she did; but in truth, Frau Heppner is a midwife. She delivered Eleanor, and has delivered many other noble and common babies since then. Eleanor said that she was loyal and that her discretion could be relied on.
