‘Hey, this isn’t your fault,’ Imogen said, knowing that Adrian would already be blaming himself for allowing the woman at the riverbank to film him. ‘She probably just left on her own. Let’s find out what happened before we freak out.’

‘I’ll go check with security, you go check the main entrance,’ Adrian said to her and rushed off.

Imogen peered into rooms as she walked briskly towards the main entrance to the hospital. The buses ran quite frequently past the hospital and so she could be on a bus, or she could have walked into the residential area. Given that they knew nothing about her, they had no idea where to look.

It wasn’t just about her, either. They had a body they needed to identify and she was the closest thing they had to a witness. Imogen accepted that the woman had probably lied about not remembering anything and if she did, then she knew the who and perhaps the why. There was no reasonable explanation for her to run away if she genuinely couldn’t remember anything about her situation. Was she afraid of getting in trouble with the police? Was she afraid of a person? Was the man who died her husband? So many more questions …

Imogen knew before she got to the exit that she wouldn’t see the woman, that there would be no way to find her. This case was feeling like one door slamming in her face after another. She pulled her phone out and called Gary to check for any CCTV of the hospital and surrounding neighbourhoods. He could put someone on it while they searched the area. She should get him to make that young PC who was supposed to be watching the woman to do it as punishment, but she wouldn’t trust him not to miss anything.

‘I heard,’ Gary said as he answered the phone. ‘The DCI has already asked me to look for CCTV and she has dispatched a couple of cars to look for Jane Doe. DI Walsh is also on his way to the hospital to speak to PC Milbourne.’

‘We are going to look here as well. Adrian has alerted hospital security in case she is still in the building, but she’s had plenty of time to get away. He said twenty minutes, but I reckon we can add at least another ten minutes to that.’

‘There are cameras on the exits to the hospital, so I should be able to get an exact time for you soon enough. I’ve got the head of hospital security on the other line. I’ll text you when I know,’ Gary said before ringing off.
