Matt hung up the phone and turned his attention to Imogen. ‘Well, what do you make of that then? Have you ever seen anything like it? I was just talking to her this morning.’

Actually, Imogen thought, she had, and a lot worse besides. But she didn’t want to disappoint him with her answer. For some bizarre reason, she wanted to please him. There was no rhyme or reason to it, other than the fact that she genuinely wanted to like Matt Walsh.

‘No. It’s pretty horrible.’

Matt Walsh’s phone beeped and he looked at the screen. ‘The DCI needs to see us, immediately.’

DCI Kapoor had three empty coffee mugs in front of her. She looked somewhat harassed and rubbed her eyes before letting out a big sigh. They were all acutely aware of how little headway they had made in the investigation and no one would be feeling more pressure than the DCI. Imogen was glad that the responsibility for this mess of a case wasn’t falling to her.

DCI Kapoor turned to them. ‘We don’t seem to be getting any closer to any kind of motive for these crimes and they appear to be getting worse. What with the allegations against Adrian as well, the press are having an absolute field day.’

‘As soon as we can figure out what the connection is, then we should make some headway. If only we could get Caitlin Watts to speak to us again,’ Imogen said.

‘That’s why I called you in. The uniformed officer stationed with her at the hospital called and asked to speak to you.’

‘What do you mean?’ Imogen said, raising her eyebrow. After everything Caitlin had put Adrian through – not just Adrian but the entire station – Imogen thought if she had to sit in the same room as her she might lose it.

‘Apparently, Caitlin has asked for you specifically, Imogen. After they asked her if she knew anything about this, about Gillian Mitchell.’

‘What? Why would she ask for me?’

‘Go and find out. See if you can push her on the exact nature of her relationship with Gillian Mitchell and anything else she might know about Doctor Norris’ murder. It’s worth ascertaining if the information she gave us before was even accurate – did he really have an affair with a student?’

‘Has she given a statement to DCC Sneddon yet?’ Matt asked.

‘She wouldn’t agree to do it until after she has spoken to Imogen. So you had both better get over there now.’

‘Not just DS Grey?’ DI Walsh said.

‘I don’t think I want any of my detectives alone with her, given what we know about her propensity for lying.’

‘OK, Ma’am,’ Imogen said; the investigation had to take precedent over her personal feelings. The truth would come out eventually, she knew that much, she just had to hope that Adrian’s career wouldn’t be over before it did.

DCI Kapoor nodded and they both stood up to leave. Imogen didn’t particularly ever want to see Caitlin Watts again, but if it meant getting a statement that could exonerate Adrian faster then she would just have to suck it up.
