that might help us find your wife.’
Puzzled, Birley looked at his sister, whose face had set into an angry expression. ‘I suppose it’ll be all right,’ he said.
The Birleys lived in a detached limestone cottage with an enclosed garden. Fry guessed there were probably three or four bedrooms upstairs. From outside, it was obvious that the property had been created by combining two cottages whose roofs were at slightly different heights. An external chimney stack at one end suggested there might have been a third cottage in the row at some time.
Fry looked first into the kitchen and saw an enamelled range, the kind that provided central heating and hot water as well as cooking. She’d never be able to manage one of those herself. In the sitting room, the focal point had been a castiron stove with a carved surround, which looked equally impractical.
In the dining room, Fry paused to admire a carving of a leaping dolphin on a table near the fireplace. There was much more light at the back of the house, thanks to a sliding door that led into a conservatory, with pine floorboards covered in raffia matting. She walked straight through it and out into the garden, past a lawn and a series of raised borders, until she found a brick store place and a garden shed that had been painted bright blue. Neither of them contained the body of Sandra Birley.
Re-entering the house, Fry saw Hitchens descending the stairs from the bedrooms. She shook her head, and they both went back into the sitting room, where they were met with a glare from Trish Neville. Geoff himself was gazing at the carved surround of the stove, as if searching for a meaning in its decorative curlicues.
‘Is that your car parked outside, sir?’ said Hitchens. ‘The green Audi?’
‘Yes. Why?’
‘Do you mind if DS Fry takes a look?’
Birley found the keys to the Audi without argument. Either he’d cottoned on by now, or his sister had explained it to him while they were out of the room.
Fry went outside and checked the interior and boot of the car. It contained nothing more incriminating than half a roll of blue stretch wrap that looked as though it might have come from the despatch department at a distribution centre.
‘I don’t know what I’ll do without Sandra,’ Birley said, as the detectives prepared to leave.
‘We don’t know that your wife is dead, Mr Birley,’ said Hitchens.
‘What? You think he might be keeping her prisoner somewhere?’
‘It’s quite possible. Until we know one way or the other, we’re keeping an open mind.’
Birley had begun to look hopeful. But now he dropped his eyes again.
‘You’re just saying that. You’ll find her dead, won’t you? You know you will. Why else would he have snatched her from that car park?’
‘Until that happens, we can still hope for the best, sir.’
As soon as he’d spoken, Fry remembered having said something similar quite recently. But she couldn’t quite recall when and where.
Detective Chief Inspector Oliver Kessen leaned against the side of the crime scene van and thrust his hands into his pockets. ‘Well, this place must be dead overnight,’ he said. ‘Do many people leave vehicles in here until morning?’
Fry assumed that the DCI was talking to her, though he gave no sign of it. Scenes of crime had almost finished with Sandra Birley’s Skoda, and were moving away along the retaining wall towards the ramps.
‘Very few,’ said Fry. ‘It’s too expensive.’
She looked around for Ben Cooper to get confirmation.
‘This is a shoppers’ car park,’ he said. ‘It’s meant for short stay. But some of the office workers use it, if they need to. The other parking facilities get full.’
‘That’s what Mr Birley told us, too,’ added Fry.
Kessen kept his eye on the Skoda, as if it might do something. Perhaps he expected it to crack open its bonnet and make a confession.
‘The attacker must have known it would be empty by that time.’
Fry nodded, though she knew Kessen wouldn’t see her gesture. He’d barely looked at her yet.
‘Yes, he certainly seems to have known his way around. There are eleven CCTV cameras in here – one on each level, and two at the entrance and exit. But he must have known exactly where they were, because none of them seem to have caught him, so far as we can tell from the attendant.’
One of the SOCOs, Liz Petty, glanced over towards them and smiled. Fry thought she’d found something significant, but she went back to dusting the edge of the wall near Sandra Birley’s car. Elsewhere, DI Hitchens was supervising a search on the stairs and in the lift, followed by the concrete parking bays between them and the car. The whole of Level 8 had been sealed off, which meant no one could reach the roof level of the car park either. Apart from the Skoda, the only vehicles here now belonged to the police team.
‘Just one attendant?’ said Kessen.
‘At that time of night, yes. He has a little office on the first level, and he monitors the cameras from there.’
‘Someone will have to go through every bit of footage.’
‘Yes, sir.’
Looking at the vehicles lined up in the multistorey car park reminded Fry that her Peugeot was due for its MoT this month. She ought to check the date on the certificate – she suspected there were only a few days left before it expired. It didn’t do a police officer’s reputation any good to be caught driving an illegal vehicle.
Sealing off the two top levels of the car park was undoubtedly causing problems. The ‘full’ sign at the entrance had already been illuminated when the first police officers arrived to look at Sandra Birley’s car. Now, frustrated motorists were continually pulling up to the barrier at ground level and reversing away again.
‘What about the lifts?’
‘They’re cleaned out every day,’ said Cooper. ‘The interiors are specifically designed for easy washing and disinfecting. It’s a familiar problem, apparently.’
‘And here I was thinking it was only a problem in high-rise flats on council estates in Birmingham,’ said Fry. ‘You’ve imported some dirty habits into Derbyshire, haven’t you?’
‘Well, I got on to the cleaning contractors a few minutes ago. They swear the lift at the Hardwick Lane entrance was thoroughly cleaned early yesterday morning. So it shouldn’t have smelled of anything but industrial disinfectant with a hint of pine forest when Mrs Birley arrived.’
‘When she arrived, yes. But somebody had been up to their dirty tricks by the time she came back for her car that night.’
‘Do you think she’d have been safer using the lift?’
Fry strode in front of the DCI and gestured at the Skoda, the SOCOs in their scene suits still clustered round it. It wasn’t a murder enquiry, not without a body. So Kessen would disappear soon. He needed to know who had the ideas at an early stage.
‘Well, look at the layout of this level,’ she said. ‘If Sandra Birley used the lift, she’d have had only a few feet to walk before she reached her car. In fact, I think it’s likely she chose that parking space precisely because it was near the lift. But the exit from the stairs is fifty yards further on, and it meant she had to pass the bottom of the down ramp from Level 9 on the way to her car.’
‘Where her attacker may have been waiting behind the concrete barrier.’
‘Exactly.’
‘So it seems her own fastidiousness led her into danger.’
DI Hitchens trotted towards them from
