“So maybe that means the ghost watches us?” Julia was getting creeped out in spite of herself. “Because otherwise how would the ghost even know you wanted the kitten? Did you leave the spool of thread here, or was it in the sewing box?”

“No, it was here.”

“Hmm.” Julia was pacing back and forth with her hands clasped behind her back. Valentina thought of a Sherlock Holmes movie they had seen over and over on Channel Nine when they were kids. Holmes was always pacing. Valentina half-expected Julia to say, It’s elementary, my dear Watson, but Julia only sat down on the floor and stared at the ottoman, frowning. “Do you think the ghost is still here?”

Valentina looked around. There weren’t very many places a ghost could be in here; the dining room was somewhat bare. “I guess,” she said. “But the ghost is mostly a feeling, at least before tonight. It’s not like I’ve ever seen it. And I don’t feel it right now.”

Elspeth stood on top of the dining-room table. She was wearing a blue chiffon cocktail dress and spiked heels with fishnet stockings. Elspeth delighted in the fact that she could walk on the smooth wood of the table without marring it. She was also tremendously pleased that she had caught the kitten, and that Valentina had seen her do it. That’s it, then. I’ve done it! They’ve got to believe in me now.

The Little Kitten of Death sat under the ottoman, enraged. She knew that there was tuna quite close by, but she did not want to give anyone the satisfaction of seeing her eat it. After a while, Julia grew bored with watching the ottoman and went to bed. Valentina put a litter box in the dining room, hoping that the kitten wouldn’t pee all over everything. She turned out the lights and also went to bed. Elspeth sat on the table, waiting.

“Sk-sk-sk,” she said, knowing the kitten couldn’t hear her. After half an hour of complete silence, the kitten crept out and looked around, circling the room, hunting for a way out. Elspeth hopped off the table and sat on the ottoman. She waited for the kitten to calm down, stroked it as it gulped down the tuna. It didn’t notice.

JESSICA STOOD in front of the Eastern Cemetery’s gates on a brisk Sunday in early March, watching the visitors assembled before the main gate on the Western side. They were an unpromising lot: an American couple wearing intimidating trainers and impressive cameras; a quiet, middle-aged man with a receding hairline and binoculars; three young Japanese men in baggy denim trousers and baseball caps; a woman with a rather aerodynamic-looking pram; and a stout man with an enormous backpack, who paced back and forth with bouncy energy.

A black van sped along Swains Lane. The gilt, circus-poster-style lettering on its side said only: TEMERITY.

Indeed, thought Jessica. She checked her watch. It was quarter to three. She glanced behind her at Kate, a round, pleasant, American volunteer who was chatting with some grave owners about the renovations to the Eastern Cemetery’s wall. When Jessica returned her gaze to the group at the gate she saw that they had been joined by two girls dressed from head to toe in white. The girls stood by themselves, holding hands. They wore white hooded sweatshirts with fur trim, white miniskirts, leggings and boots. Their white knitted caps were almost the same colour as their hair. The girls had their backs to Jessica, but she knew without seeing their faces that they must be twins. How darling they are. She wondered if they realised how muddy the cemetery paths were, and whether they were younger than sixteen.

Julia and Valentina stood in front of the gates, shifting from foot to foot and shivering. Julia wondered where everyone was; all was quiet inside the gates. She could see a wide courtyard beyond the gatehouse and a colonnade which extended in a half-circle around it. She heard someone using a walkie-talkie, but there were no people in sight. Across the road was the other half of the cemetery, where Karl Marx was buried. It looked more open, more like a regular American cemetery. The guidebook said that the Western Cemetery was more interesting, but could only be visited on the tour. Anyway, it was the Western side that the twins’ windows overlooked.

Jessica crossed Swains Lane, strode through the little crowd and unlocked the massive gates. She was dressed entirely in shades of violet and mauve, and wore a hat that Valentina instantly coveted, a large-brimmed felt affair with a sweeping black feather tucked in the band. Valentina and Julia’s first impression was of royalty, a duchess, perhaps, who had come to the cemetery for the afternoon to cut a ribbon or visit a loved one and had stayed on to help out. This notion was not immediately dispelled when she spoke. “Do come in now, my dears. Has everyone read the notices? Right, please leave all luggage in the office. I’m terribly sorry, but no children under the age of eight are allowed in the Western Cemetery. Photographs may be taken for Personal Use Only. This way, please, kindly perch yourselves in front of the War Memorial on the far side of the courtyard there, we’ll be right with you.” The twins obediently sat on a bench and waited.

Robert walked out of the office with the ticket box, distracted by a crossword clue James had just read to him. He joined Jessica and they crossed the courtyard together. He saw the twins and his stomach clenched. The sensation reminded him of stage fright; then he realised it was guilt.

“Don’t charge them,” he said to Jessica.

“Why ever not?”

“They’re grave owners.”

“Surely n-oh,” she said, looking more carefully. “I see.” They continued walking. “Will you be all right, then? Shall I ask Kate to give the tour?”

“Don’t be silly. I’ve got to meet them eventually.”

The twins watched them arrive. Julia elbowed Valentina. “Isn’t that the guy you met on the tube?” she whispered. Valentina nodded. She watched Robert tearing tickets, Jessica accepting £5 from each person. The twins were at the end of the row of benches. When she had taken the money from the American couple Jessica closed her money box and winked at them. Julia held out £10, but Jessica shook her head and smiled. The American woman gave them an annoyed look. Julia squeezed Valentina’s hand.

“Welcome to Highgate Cemetery,” Jessica said. “Robert will be your guide. He is one of our most Learned Guides, an historian of the Victorian Era, and is writing a book about this cemetery. All of our work is done on a voluntary basis, and every year we must raise over three hundred and fifty thousand pounds just to keep the cemetery open.” Jessica flirted with them as she spoke, and exhibited the green box. “As you leave, a volunteer will be stationed at the gate with this green box, and any help you can give will be Much Appreciated.” Robert watched the tourists fidget. Jessica wished them a Pleasant Tour and went back to the office. She felt a flutter of excitement. Why? She stood at the office window and watched Robert gather his group in front of the Colonnade steps. He stood two steps up and spoke to them, looking down, gesturing. From where they stood, the tourists could not see anything but greenery and the steps. Thosegirls look extraordinarily like Elspeth. How amazing life is. I hope he’ll be all right. He looked a bit pale.

Robert tried to clear his mind. He felt as though he were watching himself, as though he had separated into two Roberts, one of whom was calmly giving a tour, the other mute with nerves, trying to think what he might say to the twins. Bloody hell, you’d think you were seventeen. You don’t have to talk to them. They’ll talk to you. Wait.
