Camden Lock and Little Venice, two miles to the west in Paddington. By the following Wednesday she felt brave enough, and bored enough, to leave her refuge and visit the zoo.
It was a short walk along the canal, dodging bicyclists who jingled their bells impatiently when she forgot to stay on the proper side of the path. She passed beneath several arching bridges, their undersides pleated with slime and moss. Drunks sprawled against the stones and stared at her blearily or challengingly by turns; well-dressed couples walked dogs, and there were excited knots of children, tugging their parents on to the zoo.
Fred had walked here with Jane, to show her the way. But it all looked unfamiliar now. She kept a few strides behind a family, her head down, trying not to look as though she was following them, and felt a pulse of relief when they reached a twisting stair with an arrowed sign at its top.
REGENT’S PARK ZOO
There was an old old church across the street, its yellow stone walls overgrown with ivy; and down and around the corner a long stretch of hedges with high iron walls fronting them, and at last a huge set of gates, crammed with children and vendors selling balloons and banners and London guidebooks. Jane lifted her head and walked quickly past the family that had led her here, showed her membership card at the entrance, and went inside.
She wasted no time on the seals or tigers or monkeys, but went straight to the newly renovated structure where a multicolored banner flapped in the late-morning breeze.
AN ALTERNATE UNIVERSE: SECRETS OF THE INSECT WORLD
Inside, crowds of schoolchildren and harassed-looking adults formed a ragged queue that trailed through a brightly lit corridor, its walls covered with huge glossy color photos and computer-enhanced images of hissing cockroaches, hellgrammites, morpho butterflies, death-watch beetles, poly-phemous moths. Jane dutifully joined the queue, but when the corridor opened into a vast sun-lit atrium she strode off on her own, leaving the children and teachers to gape at monarchs in butterfly cages and an interactive display of honeybees dancing. Instead she found a relatively quiet display at the far end of the exhibition space, a floor-to-ceiling cylinder of transparent net, perhaps six feet in diameter. Inside, buckthorn bushes and blooming hawthorn vied for sunlight with a slender beech sapling, and dozens of butterflies flitted upwards through the new yellow leaves, or sat with wings outstretched upon the beech tree. They were a type of Pieridae, the butterflies known as whites; though these were not white at all. The females had creamy yellow-green wings, very pale, their wingspans perhaps an inch and a half. The males were the same size; when they were at rest their flattened wings were a dull, rather sulphurous color. But when the males lit into the air their wings revealed vivid, spectral yellow undersides. Jane caught her breath in delight, her neck prickling with that same atavistic joy she’d felt as a child in the attic.
“Wow,” she breathed, and pressed up against the netting. It felt like wings against her face, soft, webbed; but as she stared at the insects inside, her brow began to ache as with migraine. She shoved her glasses onto her nose, closed her eyes, and drew a long breath; then took a step away from the cage. After a minute she opened her eyes. The headache had diminished to a dull throb; when she hesitantly touched one eyebrow, she could feel the entwined hairs there, stiff as wire. They were vibrating, but at her touch the vibrations like the headache dulled. She stared at the floor, the tiles sticky with contraband juice and gum; then looked up once again at the cage. There was a display sign off to one side; she walked over to it, slowly, and read.
CLEOPATRA BRIMSTONE
Gonepteryx rhamni cleopatra
This popular and subtly colored species has a range which extends throughout the Northern Hemisphere, with the exception of Arctic regions and several remote islands. In Europe, the brimstone is a harbinger of spring, often emerging from its winter hibernation under dead leaves to revel in the countryside while there is still snow upon the ground.
“I must ask you please not to touch the cages.”
Jane turned to see a man, perhaps fifty, standing a few feet away. A net was jammed under his arm; in his hand he held a clear plastic jar with several butterflies at the bottom, apparently dead.
“Oh. Sorry,” said Jane. The man edged past her. He
