swallowsthan about the other goings-on at Burdem Place. Julietâs pregnancy has made her ill-humoured, and Christopher has changed as well. Sarah Anne knows she should have expected this, but still it has come as a shock. These days the guests tend to be Julietâs frivolous friends and not the older naturalists. Young, not old; some of them younger than Sarah Anne herself. For weeks at a time they stroll the grounds in fancy clothes and play games while Sarah Anne hovers off to the side, miserable in their company.
Who is she, then? She doesnât want to act, as Christopher does, the part of her parentsâ generation; but now sheâs found that she doesnât like her own peers either. She fits nowhere. Nowhere, except with Catherine. She and Catherine, tucked into a wing away from the fashionable guests, have formed their own society of two. But she suspects that, after the birth of Julietâs child, even this will be taken from her.
Christopher hopes for many children, an army of children. This child, and the ones that follow, will need a nurse and a governess, Juliet says. And a nursery, and a schoolroom. Sarah Anne has seen Christopher prowling the halls near her bedroom, assessing the space and almost visibly planning renovations. Heâs welcomed Catherineâs frequent long visitsâbut only, Sarah Anne knows, because they keep her occupied and him from feeling guilty about her increasing isolation. The minute he feels pinched for space, heâll suggest to Sarah Anne that Catherine curtail her visits. And then itâs possible heâll ask Sarah Anne to be his childrenâs governess.
But Sarah Anne and Catherine donât talk about this. Instead they look once more at Linnaeusâs letter, which arrived addressed to âMr. S.A. Billoppâ but which, fortunately, Christopher didnât see. They arrange their instruments on the bench beside them and shiver with cold and excitement. They wait. Where is Robert?
It was Catherine who first approached this weedy twelve-year-old,after Sarah Anne told her sheâd once overheard him talking about netting birds for food in Ireland. Catherine told him that they required two or three swallows and would pay him handsomely for them; Robert seemed to believe they had plans to eat them. Still, at 4:30 he met them here, silent and secret. Now he reappears in the doorway, barefoot and wet to the waist. His net is draped over one shoulder and in his hands he holds a sack, which pulses and moves of its own accord.
âRobert!â Catherine says. âYou had good luck?â
Robert nods. Both his hands are tightly wrapped around the sackâs neck, and when Catherine reaches out for it he says, âYou hold this tight, now. Theyâll be wanting to fly.â
âYou did a good job,â Catherine says. âLet me get your money. Sarah Anne, why donât you take the sack?â
Sarah Anne slips both her hands below Robertâs hands and twists the folds of cloth together. âI have it,â she says. Robert releases the sack. Immediately sheâs aware that the sack is alive. Something inside is moving, leaping, dancing. Struggling. The feeling is terrifying.
âThank you, Robert,â Catherine says. Gently she guides him out the door. âYouâve been very helpful. If you remember to keep our secret, weâll ask you for help again.â
By the time she turns back to Sarah Anne and takes the sack from her, Sarah Anne is almost hysterical.
âNothing can satisfy but what confounds,â Catherine says. âNothing but what astonishes is true.â Once more Sarah Anne is reminded of her friendâs remarkable memory. When Catherine is excited, bits of all she has ever read fly off her like water from a churning lump of butter.
âAll right now,â Catherine says. âHold the netting in both hands and pull it over the tubâthatâs good. Now fasten down the
