‘It’s been mayhem.’ He turned away from the shop so we were out of earshot. ‘I had a feeling you’d turn up when you heard it was the old bagel shop.’ Affection creased the corners of his mouth before he switched into professional mode. ‘Uniform have begun eyewitness interviews, including some of the teenagers from the flash mob. The woman with the sling was on her way to visit her mum and someone pulled her into the crowd. She fell on her wrist. The young lad by the door is anxious to get moving – something about his parents being worried. His English isn’t great so it’s hard to figure out exactly what he saw, but the priority is to get stitches over that cut before he gets a nasty infection. He’s already feeling dizzy. Rima’s on her way to interpret.’

I was absorbing the details. ‘A flash mob and arson?’ I frowned the question.

The three of us began walking towards the burnt building.

‘It is a bit of a coincidence,’ Dougie replied.

My mind was spinning.

Dougie wiped his blackened face with the sleeve of his jacket. ‘The fire investigators think the blaze started on the ground floor. Probably at the foot of the stairs. It would then have spread quickly upwards, building in intensity, and then blown out the windows. The top floor has collapsed under the weight of the water.’

‘In that case, I’ll get the H-2-H teams started so we don’t waste time.’ I glanced ahead. A neon sign lay on the ground. Over the front of the shop, smoke-charred in places, I made out ‘SOUP’. I turned to face the shop opposite the fire and felt nostalgic momentarily.

FELDMAN’S NEWSAGENT.

‘Dad often brought us here. He and Mr Feldman were pals.’

Suddenly, I heard something. Faint and weak, but its distress gnawed through the air. ‘What’s that? I can hear someone.’ I wheeled round, trying to locate the source. ‘It’s coming from one of the shops.’ There it was. ‘It’s the newsagent’s. Someone’s calling for help.’

I dashed over to the shop; pushed the door open and entered the shop alone. ‘Hello? It’s the police.’

A different smell greeted me. Musty. Less of the acrid smoke, and the water-drenched tarmac and masonry; this was damp timber and plaster. It reminded me of our first flat. In the dim light, it was like stepping back in time. It was as if the whole place hadn’t been touched for thirty years, and suddenly I was a child again, in here with my brother and sister, choosing sweets.

‘Help, help,’ came the voice, followed by a series of rasping coughs.
