friends now and doesn’t need the imaginary one.’
‘Do you think so, Ben?’
‘With the best will in the world, it was a bit lonely up here for Josie when Amy was already at school and she wasn’t.’
‘Time will tell, I suppose,’ said Matt. ‘But I have to find out the facts. It was me who made the decision to have children. Well, me and Kate.’
‘Have you talked to Kate about it?’
Matt ran a hand across his face. ‘I need to know what to tell her first.’
‘When you were looking up all this information on the internet, did you come across any advice? What do they say you should do?’
‘Talk to a psychiatrist.’
‘And that’s what you’re going to do, right?’
Matt sighed. ‘According to some of these websites, the genetics of mental illness will be much better understood in twenty years’ time. But there isn’t much chance of research having practical applications within five years – when it would be useful to me. Or useful to you, Ben.’
‘I’m not planning on having kids any time soon.’
‘You’re past thirty. You won’t want to wait that much longer. Men have a body clock, too.’
‘If you say so.’
‘What about that girlfriend of yours?’
‘Liz? We’re just … Well, we’re just going out together, that’s all.’
Matt raised his eyebrows and gave him a sceptical glance.
‘What?’ said Ben.
‘Nothing. I just think you’ve been different since you got together with her.’
‘No, I haven’t.’
His brother snorted. ‘Be that as it may. In the end, Ben, you’ll have to face the fact that no one can tell you whether a child of yours will be healthy, or vulnerable to schizophrenia.’
‘That’s one thing I’m not going to worry about,’ said Ben firmly.
A few minutes later, he left his brother in the office and went out into the passage that ran through the centre of the house. When he was a child, the passage and stairs had been gloomy places. He remembered dark brown varnish, and floorboards painted black alongside narrow strips of carpet that had lost its colour under layers of dirt.
Things were very different now. There were deep-pile fitted carpets on the floor, and the walls were painted white. Or maybe it was some shade of off-white. Kate would know the exact name from the catalogue. The wood had been stripped back to its original golden pine and there were mirrors and pictures to catch the light.
Reluctantly, Ben turned and looked up the stairs. At the top, he could see the first door on the landing, the one that had been his mother’s bedroom. After the death of his father, she had gradually deteriorated until the family could no longer hide from each other the fact that she was mentally ill.
Isabel Cooper had been diagnosed with chronic schizophrenia, and finally the distressing incidents had become untenable, especially with the children in the house. Ben shuddered at the memory. He never wanted to witness anything like that, ever again.
On a Monday night in October, Matlock Bath’s Derwent Gardens were deserted. There was no one to be seen on the paths between the flower beds and the fountain, no one near the bandstand or the tufa grotto. The sycamores along the riverside were turning golden yellow. Their leaves drifted across the paths, undisturbed by passing feet.
At the far end of the gardens, past a row of stalls under striped awnings, was a temporary fairground. An old-fashioned waltzer and a ferris wheel, a train ride, a set of dodgem cars, all silent and still.
A figure approached from the direction of the Pavilion, a man in an overcoat, walking along the river bank, past the jetty where boats were tied up ready to take part in Saturday’s parade. He wandered apparently aimlessly, kicking at tree roots, making the fresh, dry leaves crackle under his feet.
He passed the waltzer and ferris wheel and found himself near a small hut that served as a ticket booth for the rides.
By the door of the hut, he stopped. There was no one visible in the darkness inside. But still he kept his eyes turned away, gazing up at the tower on the Heights of Abraham, high above the village. That was the place he’d rather be, surrounded by rushing air, with the wind loud in his ears. But the hilltop amusement parks had closed for the day.
‘It’s done, then? All over with.’
He froze. The whisper might have come from the hut, or from the river bank behind him. Or it might have been inside his head.
‘Yes, all over,’ he said.
Beyond the hut, he could see the dodgems lurking in the gloom of their wooden circuit, like a cluster of coloured beetles. There was a Rams windscreen sticker on a Leyland truck, backed up on the other side of the circuit. One of the operators of the fairground must be a Derby County fan. He wondered if the truck contained the generator that ran the cars, bringing life to the beetles, making them crackle and spark.
‘You’re evil, aren’t you?’
‘Am I?’ he said.
‘Really evil.’
He was distracted by the sound of the fountain splashing. A spray of water caught by the breeze spattered on to the rose bushes. Tip-tap, like tiny footsteps.
‘I’m not listening any more.’
Laughter swirled in his mind, making him shiver. ‘Too late.’
John Lowther pulled his overcoat closer around his shoulders as he walked away, scuffing his feet in the leaves. He didn’t know what he was supposed to do next. And he wasn’t at all sure about the voice, that awful disembodied whisper. It had sounded like the voice of a child.
Tuesday, 25 October
An incident room had been opened up in Edendale for the Rose Shepherd enquiry. A fatal shooting was still rare enough in Derbyshire to make Miss Shepherd’s murder a high-profile case, even if she hadn’t been a respectable middle-class woman gunned down in her own home.
Watching the staff arriving at E Division headquarters, Cooper deduced that the HOLMES system was being activated. He recognized an allocator he’d worked with on a previous enquiry. The others would be data inputters, a receiver, an analyst.
With no obvious lines of enquiry that might lead to a quick conclusion, the HOLMES computer indexes would be vital in sniffing out correlations as information came in. One tiny detail could send the investigation in a new direction.
Before the morning briefing started, Cooper joined a small crowd examining the
