‘Ma’am?’‘Yes?’‘Ma’am, I wasn’t sure at the time but come and see this.’ He waved to her to follow him to his desk. He had a still from the car park CCTV streamed into his desktop. A grainy picture showed the front of a small white van parked across the road. The licence plate was readable.She looked at him for an explanation.‘The van’s registered to a private individual, Matthew Stepper. He works for newspapers.’She looked at the screen. ‘And it’s outside here right now?’‘Aye.’Morrow and McCarthy stood on the pavement outside the station. They watched the white van wobble, rain bouncing off the roof. They were both trying hard not to laugh. Whoever was inside was pretending they weren’t but every time they moved the entire body shifted. They watched for a while, uncertain they could speak without howling, and then finally Morrow banged on the side.‘We can see you moving in there. Come out.’Hissing whispers inside, there must be two of them. Then someone moved again, down to the front, looking out of the windscreen.
