course.â
In their excitement theyâve been walking so fast that theyâve left Juliet behind. They hear the men calling them and stop. Quickly, knowing she has little time, Sarah Anne asks the remaining important question. âAnd your husband?â she says. âHe shares your interests?â
âHeâs dead,â Mrs. Pearce says calmly. âIâm a widow.â
She lives in London, Sarah Anne learns, alone but for three servants. Both her daughters are married and gone. âI would be so pleased if you would visit us,â Sarah Anne says. âWe have a place just a few miles from town, but far enough away to have all the pleasures of the country. In the gardens there are some interesting plants from North America, and weâve quite a large libraryâ¦â
Mrs. Pearce lays her gloved hand on Sarah Anneâs arm. âIâd be delighted,â she says. âAnd you must visit me in town. Itâs so rare to find a friend.â
The others join them, looking cold and displeased. âMiss Colden,â Mrs. Pearce says.
âMrs. Pearce. I do hope you two have had a nice talk.â
âLovely,â Mrs. Pearce says.
She looks over Julietâs head at Sarah Anne. âIâll see you soon.â Then she hooks her hand into Mr. Hillâs arm and walks away.
âOdd woman,â John says. âBit of a bluestocking, isnât she?â
âShe dresses terribly,â Juliet says, with considerable satisfaction. From the sharp look she gives Sarah Anne, Sarah Anne knows sheâll pay for that brief bit of reviving conversation. But her mind is humming with the pleasure of her new friend, with plans for all they might do together, with the letter sheâll write to Linnaeus the very instant she reaches home. She imagines reading that letter out loud to Mrs. Pearce, showing Mrs. Pearce the response she will surely receive.
âWe should write him about that old potion,â Mrs. Pearce says; and Sarah Anne says, âWhat?â
âFor melancholy. Donât you know it?â
âI donât think so.â
âItâs a potion made partly from the blood of swallows. Birds of summer, symbols of easeâthe potion is supposed to ease sadness and give wings to the feet.â
âMore likely than what heâs proposing,â Sarah Anne says, and Mrs. Pearce agrees.
Itâs September nowânot the September following their meeting but the one after that: 1764. The two women are in an unused stable at Burdem Place, patiently waiting, surrounded by their equipment. It is just barely dawn. Down in the reeds, where the birds are sleeping, theyâve sent Robert the gardenerâs boy with a net and instructions. What theyâre talking about while they wait is the letter Sarah Anne received last week from Carl Linnaeus, in which he graciously but firmly (and in Latin; but Sarah Anne can read it), dismissed her theories and stated his absolute conviction that swallows hibernate under the water. The letter upset Sarah Anne, but she would not have done anything more than fume had Mrs. Pearce not been visiting. It was Mrs. PearceâCatherineâwhoâd said, âWell. Weâll just have to do the experiments ourselves.â
On the wooden floor theyâve set the bottom half of a cask, which Robert has filled with water. Below the water lies a few inches of river sand; on the surface a board floats an inch from the rim. A large piece of sturdy netting awaits the use to which theyâll put it. Inside the stable itâs still quite dark; through the open door the trees are barely visible through the mist. Above them the house sleeps. Just after four oâclock, Sarah Anne rose in her new room and tapped once on the door of the room down the hall, where Catherine stays when she visits. Catherine opened the door instantly, already dressed.
Recently it has been easier for them to talk about the
