Then the crowd was silenced by a terrific bang that hit the village like a huge hand had been slapped down on the landscape. It punched eardrums and stopped a few hearts, judging by the expressions on the faces around him. It was the maroon, the single loud report that signalled the start of the display.

The maroon was followed by flares, fountains and rockets, candles. Brilliant white star bursts and red blossoms. They produced a barrage of bangs and whistles, whizzes and crackles, intense light and smoke. Glittering, coloured fire hung over the tor. A canopy of colour exploded into sparks, bangs, crackles and whistles. He saw the characteristic sparkling tail of a rocket on its way up. Screamers and screechers chased each other into the sky. Small stars and balls of fire changed colour in flight, finishing with a series of bangs. Comets grew brighter, their tails splitting into small fragments. Serpents snaked and wriggled through the air.

‘Hold on. Diane, I can see him.’

‘Brian Mullen?’

‘Yes.’

‘Are you sure?’

‘It’s him and Luanne. They’re right down the north end of the gardens, near where the boats are docking after the parade.’

‘Can you get to them, Ben?’

‘I’m on the wrong side of the river. The nearest crossing is the footbridge. I’ll have to go back and cross over.’

‘Which way is Mullen heading?’

‘He’s standing still at the moment. No, wait – he’s moving.’

‘Has he seen you, do you think?’

‘I don’t think so. I’m on the darkest part of the bank over here. But he’s moving all right. God, he’s running. Diane, he’s started to run. He’ll be on the road in a minute.’

‘I’ll get back to the car and drive down. Gavin, where are you?’

‘By the ice-cream kiosk in the Pavilion car park.’

‘Get to the road, and I’ll pick you up.’

There was no way of spotting Brian Mullen again, once he’d disappeared into the crowd. There were too many paths up there in the trees, too many dark corners, too many members of the public in the way. And too many of them were parents with small children.

‘I’m pretty sure there’s no way out at the other end of the gardens,’ said Cooper. ‘Not unless you’re fit enough to scramble up the slope and get over that wall. Mullen couldn’t do it with a small child in tow.’

‘So he’ll have to come back this way?’

‘The nearest way out on to the road is by the netball court. I left my car at this end, Diane – opposite the church.’

‘OK, we’ll catch you up. Don’t worry, he hasn’t got a big start on us.’
