‘She came to see me, and it very quickly became apparent that she wanted, wanted to . . . Well, she wanted to have sex.’

‘And how did she indicate this?’ asked Moss.

‘How do you bloody think!’ said Giles, growing red. He looked around, desperate to be somewhere else. ‘She lifted her sweater and exposed herself. Told me that no one would know.’

‘And what did you do?’

‘I told her where to go. Even if she wasn’t Andrea’s sister, she’s not exactly . . .’

‘Not exactly?’

‘Well she’s not exactly a looker, is she?’

Moss and Erika remained silent.

Giles went on, ‘As far as I’m aware it’s not a crime to find someone . . .’

‘Repulsive?’ finished Erika.

‘I wouldn’t go quite that far,’ said Giles.

‘And then things turned nasty. Linda vandalised your office and, according to the records, broke in and poisoned your cat.’

‘Yes, and I don’t know. You’ve read the case files, then?’

Erika and Moss nodded.

‘I found myself with an unfortunate dilemma with Linda. Sir Simon asked me to drop the charges. What could I do?’

‘I’m sorry to have to bring this up, Giles, but were you aware that Andrea was seeing other men when you were together?’ asked Erika.

Giles paused. ‘I am now.’

‘And how does that make you feel?’

‘How do you bloody think that makes me feel?! We were engaged. I thought she was the one. Sure, she liked to flirt and play, and I should have seen it, but I thought she might calm down once we were married, and then we’d get sprogged up.’

‘Sprogged up?’ asked Erika. ‘You mean, have children?’

‘Yes. I had no idea she had several men on the go. She was so stupid to get involved with that hateful creature Marco Frost. He scared Andrea with his obsession. Do you think you have enough evidence to secure a prison sentence?’

Erika looked at Moss. ‘Mr Osborne, can I please ask you to take a look at this photo?’ She placed the picture of Andrea with the dark-haired man on the table. He glanced at it.

‘No. I don’t know him.’

‘I didn’t ask if you knew him. Please take a good look; this was taken just four days before Andrea disappeared.’

Giles looked at the photo again. ‘Well, what am I looking at? He was probably one of the many men who make eyes at her.’

‘What about this? Or this . . . or this?’ asked Erika. She placed the series of photos in front of Giles: Andrea lying in bed with the dark-haired man, naked, her nipple drawn between his teeth, then Andrea with her lips spread wide and his penis in her mouth.

‘What are you people doing?’ cried Giles, pushing his chair back and getting up. There were tears in his eyes. ‘How dare you come in here and take advantage of my good will!’

‘Sir, these are from Andrea’s second mobile phone which we recently recovered. We showed these photos to you for a reason. They were taken just a few days before she vanished.’

Giles stood and went to the glass door. ‘Thank you, officers, but I came into my office today to remember Andrea, and write about her life. I have been asked to speak at her funeral, and you come here and sully my memories of her with hardcore pornographic photos!’ He opened the door and indicated that they leave.

‘Sir, we believe that the man pictured with Andrea is also involved in the killing of three Eastern European girls who worked as prostitutes, and the murder of an elderly lady. We also believe that Andrea was with this man on the night she died,’ explained Erika. She looked at Moss. Giles saw their exchange.

‘Hang on. What about Marco Frost? I thought he was your man? Chief Superintendent Marsh assured me, and Assistant Commissioner Oakley . . .’ said Giles.

‘This is another line of enquiry we are pursuing,’ said Erika.

‘So you really have no idea who killed Andrea? Yet you come over here hassling me, on a hunch? Andrea was a flawed human being, and she had secrets. But all she did was love, all she wanted was to love . . .’ Giles broke down, heaving and sobbing. He put his hand to his mouth. ‘I just can’t take this much longer. Please! Leave!’

Erika and Moss went back to the table, gathered up the photos and left, leaving Giles to sob.

‘Oh fuck,’ said Moss, when they came back to the car parked a few roads away.

‘I said it, not you,’ said Erika.

‘Boss, I have to go and report this all to DCI Sparks, and Marsh.’
