“So you think it’s more likely that he met someone by arrangement?”

“Not necessarily. It might have been a chance meeting that turned nasty.”

Lindsay recalled Crabtree’s distinctive figure. “Your father would have been easy to recognize at a distance and chase after if you were looking for a chance encounter. After all, Deborah thought she spotted him from quite a way off on the night he died, when he was walking the dog,” she added. “And she wasn’t even on the common. She was walking back from the phone box.” Simon shrugged. “But he was carrying a gun, Simon,” Lindsay continued. “Surely that suggests he was expecting trouble?”

Simon paused to think. “Yes, but maybe he was just expecting trouble in a general way and had started carrying the gun when he took Rex out last thing.”

Lindsay shook her head in disbelief. “This is rural England, not the New York subway. People don’t wander round with guns just because they think someone might give them a hard time. If he was genuinely afraid of being attacked, if he’d been threatened in any serious way, surely he’d have gone to the police?”

Simon shrugged. “Don’t ask me. It would probably have given him a buzz to confront someone with his gun and then turn them over to the cops. And I think he was genuinely frightened by those peace women. Especially after that one attacked him.”

Lindsay shook her head. “I can’t believe he thought the peace women were coming after him,” she said. “It must have been something else. He said nothing?”

“No. And if you’ve no more questions, I’d appreciate the chance to get back to work,” he replied.

“Okay. Thanks for the time. I’m sure Ros will appreciate your solidarity,” she threw over her shoulder as she left.

Back in the car, she scribbled down the names of the computers she had seen and drove off, keeping an eye out for the red Fiesta. But her rear-view mirror was clear, so she stopped at the first phone box she came to. Typically, it was prepared to allow 999 calls only. Three boxes later, she found one that would accept her money, and she dialed an Oxford number. She was quickly connected with a friend from her student days, Annie Norton, a whiz kid in computer research.

After an exhaustive exchange of gossipy updates while she pumped coins into the box, Lindsay wound her way round to the point of the call. “Annie, I need your help on an investigation I’ve got tangled up with,” she tossed into a gap in the conversation.

“If it’s anything to do with Caroline Redfern’s much publicized love-life, my lips are sealed,” Annie replied.

“No, this is serious, not chit-chat. It’s about computers. I’ve acquired a cassette tape that I think is a computer program. It could have been made on any one of four computers, and I need to know what it says. Can you help?”

“A cassette tape? How extraordinary. We’re talking real computers here, are we, not video games?”

“I think so, yes.”

“Hmm. No indication of what language it’s in?” Annie asked.

“English, I suppose.”

“No, no, what computer language-BASIC, FORTRAN, ALGOL, etc., etc.”

“Oh,” said Lindsay, bewildered. “No, nothing at all, unless there’s a computer language called Sting: The Dream Of The Blue Turtles‘:’

“What? Are you serious?”

Lindsay laughed. “No, that’s what’s written on the cassette, that’s all.”

“And what computers are we talking about?”

“An Apple Macintosh, an IBM, an Apricot, an Amstrad, and a Tandy.”

“A Tandy? Little lap-top job, would fit in a briefcase? With a flip-up screen?”

“Yes, that’s right.”

Annie sighed in relief. “That explains the tape. It’s probably been transferred from one of the other machines,” she mused. “It should be fairly simple to run it through our Univac and read it for you. When can you get it to me?”

“I could drop it off in an hour or so-I’m only down the road in Fordham.”

“Tremendous. We could have dinner together if you fancy it.”

Lindsay was tempted. She had reached the point where she wanted more than anything to walk away from the conflict of interests with the peace camp, the police, and the job. She felt guilty about two-timing Cordelia and was unsure how she felt about Debs. But she had promised to be at the vigil, and she had to keep that promise. She could just fit in the round trip to Oxford if she didn’t hang about too long with Annie. “Sorry,” she said. “But I’m working tonight. Maybe when I pick it up again, yeah? How long will it take you?”

“Hard to say. A day? Two, maybe, if it’s not something obvious. If the person who’s made it is a real computer buff, which he or she presumably is, if they really use those four systems to their full potential, then it could be a bit subtle. Still, a nice bit of hacking makes a pleasant change. I’ll see you again in about an hour, then. You know where to find me?”

“Sure, I remember. I’ll be with you soon as possible.” Lindsay rang off and was about to leave the box when she realized she hadn’t spoken to Cordelia since her angry departure on Monday. Her mind had been too occupied with Crabtree and Debs for her to pay attention to her lover’s needs. It wouldn’t be an easy call, for Lindsay knew she’d have to lie about what had happened with Debs. The phone wasn’t the place for confessions. And Cordelia would be quite justifiably hurt that Lindsay hadn’t made time for her. Especially with Deborah Patterson back on the scene. The stab of guilt made her rake through her pockets for more change, and she hastily dialed their number. On the fourth ring, the answering machine picked up the call. “Oh shit,” she muttered as she listened to her own voice instructing her to leave a message. After the tone, she forced a smile into her voice and said, feeling foolish as she always did on their own machine, “Hello, darling, it’s me. Wednesday afternoon. Just a check call to let you know I’m okay. Duncan ’s leaving me here on the murder story because of my peace camp contacts, so God knows when I’ll be home. Probably not till after the funeral, or an arrest, whichever comes first. I’ll try to ring tonight. Love you. Bye.” She put the phone down with relief and set off for Oxford.

Deborah was waiting impatiently by the Gate Six encampment for Lindsay. Already, most of the women taking part in the vigil were in place. The traffic on the main road back from Oxford and the need to change into more suitable clothes had delayed Lindsay enough for her to have missed the procession, but she could see that there were not sufficient numbers there to encircle the base holding hands. They had spread out along as much of the perimeter as they could cover, with gaps of about fifty yards between them. The flicker of candles, feeble against the cloudy winter night, was gradually spreading.

Deborah hustled Lindsay along the muddy clearing by the fence for half a mile till they reached their agreed station, a corner of the fence near a deep drainage ditch. They kissed goodbye, then Lindsay walked on round the corner to her position.

She turned facing the base, where the buildings and bunkers were floodlit against the enemy-not the red menace, but the monstrous regiment, she thought. She turned back and peered towards the nearest flame. She could just make out the silhouette of the next woman in the vigil and in the distance she could hear the faint sound of singing. She knew from experience that it would soon work its way round to her like Chinese whispers. She had been pleasantly surprised to see, for once, the police and military presence were fairly low key. She hadn’t seen any journalists, but assumed they would all be down by the main gates, reluctant to stagger through the mud unless it became absolutely necessary. She smiled wryly. At least her story would have the unmistakable air of verisimilitude.
