Imogen noted that Caitlin’s face looked a lot better than it had the last time she had seen her. The bruising was fading and coming out, and there was no more swelling. Even knowing that the girl had lied, Imogen felt pity towards her. Whatever part she was playing in this mess, she was not the mastermind. She was sat up in bed, watching the television, when Imogen and DI Walsh opened the door.

Caitlin looked instantly guilty as soon as she saw Imogen, and the tears started to flow. She picked up the TV remote and flicked off the telly. She scooched up a little in her bed, wincing and instinctively reaching for her side.

‘Miss Watts, I hear you wanted to speak to us. Do you wish to change your statement from earlier?’ DI Walsh said.

‘Please don’t be angry with me. I was only doing what I was told,’ Caitlin said.

‘What are you talking about?’ asked Imogen.

‘That day, when you came to the university and you asked questions about Doctor Norris. Gillian was really angry about that. And then when she saw that I knew you both, she told me that I had to do something for her. She said she needed some time and that I was to derail your investigation. She told me that I had to get DS Miles alone; she wanted me to sleep with him. After I had slept with him, she wanted me to claim that he had raped me.’

‘Why would she do that?’ DI Walsh said.

Caitlin just shook her head and looked down.

‘Why didn’t you have sex with him then? What went wrong with your plan?’ Imogen asked, trying to ignore that part of her that didn’t want to know the answer.

‘I tried. I flirted with him. I was attracted to him and I thought he was attracted to me. But when I asked him inside for a drink, he said no; he didn’t even hesitate. At that point I knew he wasn’t gonna take the bait. He was just being nice, and I fucked him over,’ Caitlin said, tears hovering at the corners of her eyes, the blue magnified under the glaze.

Imogen found those tears annoying; after what Caitlin had put Adrian through, she didn’t have the right to be upset.

‘Do you know what Gillian Mitchell’s involvement was in Doctor Norris’s murder?’ DI Walsh asked.

‘I can’t talk to you about that. I shouldn’t have even said this much. I just wanted to make sure that DS Miles wasn’t still in trouble,’ Caitlin said.

‘What do you mean? Why shouldn’t you have said this much? What aren’t you telling us?’ DI Walsh said.

‘I’m already in deep shit for saying as much as I have. But, now that she’s gone, I just had to tell you the truth about DS Miles. He never touched me. I’ll tell whoever you want me to tell.’

‘Has someone been putting pressure on you to change your statement? Has DS Miles contacted you or threatened you in any way?’ DI Walsh said.
