‘Angela has managed to get something from this,’ I say, pointing at the photo of Anna’s cheek. ‘Even though it is a partial print, Angela is certain it’s a size twelve boot. The tread is consistent with those found on Caterpillar Shiftstick boots. We think the killer bought them new very recently as the print shows no signs of wear and tear. It could have been the first time he’s ever worn them. This theory is in keeping with what Zed said about the homeless man wearing boots that didn’t have a scuff on them.’

I turn to Angela.

‘Any luck getting through to Ed?’ I ask.

She stands up and faces the team.

‘I haven’t been able to get through to him personally, though I do have a mobile number for him. It keeps going to voicemail. His agent has confirmed that he has travelled to the Scottish Highlands for a writing retreat. It started the day after Anna was murdered and finishes today, so we may have a chance of getting in touch with him either later today or tomorrow. He has that joint event with the director,’ she points at the picture of Reuben, ‘in The Book Club in Manchester the day after tomorrow.’

‘Might it be an idea to have some police presence at the event?’ asks the DCI to the room.

‘Good idea, Chief,’ I say, ‘I’m happy to go. Reuben seems to think I’m alright, despite falsely accusing him of murder.’ The room fills with laughter. I think we can rule him out as a suspect now. His alibi has been confirmed.’

‘I’m happy to go too,’ chimes Tom. ‘I’m a fan of The Threat books so it’ll be interesting for me to see what the author is up to next.’

‘It’s a date!’ says the Chief, a hint of a smile in the upturned corners of his mouth. Is that a knowing smile or am I being paranoid?

‘Right everyone, next steps; monitor Rory’s movements once the ANPR hits come in and find out who this homeless, or fake homeless, or whatever, man is.’

He turns as if to return to his office, before calling, ‘Erika, my room please.’

‘I know you’re not going to like this’ is never a good opening gambit, but it’s what the Chief has opted for.

‘I’ve arranged for you to have counselling,’ he says gently. ‘What you went through last year was horrific, and I think you should discuss what you are feeling with a professional.’

I know his intentions are well meaning, though I still let out a loud sigh.

‘I suppose I don’t have a choice?’ I ask, sounding slightly like a stroppy teenager.

‘You don’t, I’m afraid. I have a duty of care to my staff and I think this will be very beneficial for you. Your first session is this evening,’ he adds, with the hint of an apologetic smile.
