She continues, ‘The van is registered to Josef Olinski and was part of his small fleet, which as you may recall, was destroyed by the fire. According to ANPR the last sighting of the van saw it head out of Streatham to the A23, and possibly onward to the Anywhere Delivery Brothers location. Because it’s a remote place we lost it after that. That said, it’s my opinion the van was left at the site and the killer took Billy Perrin in another vehicle.’

‘Do we think the Olinskis were involved in any way?’ asks Pierce.

Tozer interjects, ‘Ma’am, we spoke to Josef Olinski’s wife and she confirmed that an unnamed client had requested use of their fleet. He paid very well apparently so neither of the brothers asked any questions.’

‘OK, let’s move on. Is there a connection between the three victims in the cabinets?’ asks Pierce.

‘There doesn’t seem to be any connection other than the three men were homeless. They had no prior relationship of any significance.’

‘And what of the cabinets. Where did they come from?’

‘We found the maker and distributor from the translation of Olinski’s office diary. We contacted him and confirmed they were ordered and picked up by the brothers,’ replies Os.

‘How many cabinets were ordered?’ asks Archer.

‘For this recent transaction, he ordered nine. All paid for in cash.’

‘Recent transaction?’

‘He had placed a previous order for four cabinets.’

Pierce’s face drops. ‘So we can expect ten more murders? That’s just bloody marvellous.’ The DCI shakes her head. ‘Let’s hope it doesn’t come to that. Was there anything else in the diary?’

‘Nothing that sticks out, ma’am,’ replies Archer.

Pierce begins to tap her pen on the table top.

DC Phillips speaks. ‘The application for the exhibition was made by a lawyer acting on behalf of the artist . . . I mean, killer. Unfortunately, both the name and lawyer’s address were false.’

Pierce rolls her eyes. ‘Of course they were.’

Phillips continues, ‘The court order for taking down the videos is in progress. However, they keep popping up on other sites. People copy them and redistribute them making it an almost impossible task.’

Pierce’s tapping increases. ‘What else?’

‘The mobile number in Josef Olinski’s diary remains off-grid. My colleague at the NCA has written code that will alert her if it goes live again.’

Pierce nods her head, but says nothing.

‘Blond hairs were found on the bodies of Billy Perrin, Noel Tipping and Stan Buxton. We’re awaiting DNA on those although the formaldehyde may have compromised the quality. Unfortunately, the same formaldehyde has wiped away any DNA from the coats worn by the three victims.’

No one says anything for a moment.

‘Is that everything?’ asks Pierce, breaking the silence.

Archer looks to Hicks. ‘DI Hicks, please share with us your findings from yesterday.’

‘My findings?’

‘What did you two get up to yesterday?’
