I peered through the windows of the BMW and saw Guleed grappling with Lesley on the other side. I couldn’t risk the crossfire on the roadway, so I clambered awkwardly around the back and arrived just in time to see Guleed snap her head forward and land as sweet a Glaswegian kiss as was ever administered outside the National Club in Kilburn. Lesley staggered back, clutching her nose, and before she could recover Guleed had her spun around with her right arm in an elbow lock and I, upholding the fine tradition of the Metropolitan Police Service, piled in behind. I’m sure, had she thought about it, Lesley would have approved.

I hooked her feet out from under her, she went face down and I pulled the speedcuffs off my belt. It wasn’t that easy while trying to hang on to my staff, and I only had one of her wrists snapped when the white Humvee lurched half a metre over and squashed us up against the side of the BMW.

‘God, Peter,’ said Lesley. ‘Why are you so clumsy with the cuffs?’ And she elbowed me in the nuts. It hurt, but it would have hurt a lot more if I hadn’t been wearing the box that’s part of my PSU kit. I’ve been smacked in the bollocks before, and try to learn from my mistakes.

The Humvee lurched again, and we would have been crushed if it hadn’t been for its high clearance, which allowed all three of us to slide underneath it.

‘Shit,’ said Lesley, ‘he’s getting away!’

I followed her gaze and saw a pair of legs climbing into Reynard’s Renault. It was Reynard himself – I recognised the skinny hipster jeans as they climbed through the passenger door. The engine started, no microprocessors to fry on that car, and it started to pull out of the parking spot.

‘Where does he think he’s going?’ asked Guleed, which was a good question because there was no ramp up to the surface. Only the two vehicle lifts, and they were in lock-down.

Lesley wriggled and I was trying to get a grip on her other wrist when she was dragged out from under the Humvee and into the roadway. Since me and Guleed were hanging onto to her, we went too.

The sprinklers had finally stopped, leaving the decking a wet cold slick and the air full of the smell of stale water. I noticed that some serious puddles had accumulated in some of the parking bays and around the entrance to the lifts. Whoever had put the nice resin coating down had skimped on the drainage system.
