Suzy rested her guidebook on the table and I looked up. The target had come out of the door and was soon climbing back over the fence. The source waved, then got out of his cab. In the stronger light I could see he was definitely Indonesian, with high cheekbones, short black hair and a moustache, about the same height as Suzy. His stripy shirt hung out of his jeans, maybe because his massive shoulders were stretching the material so much – he looked as if he'd forgotten to take out the extra-wide coat hanger before putting his shirt on.

The two men came together without greeting, then went through the same door the target had come out of. Suzy packed her book back into her bag as the Brits eyed up a group of girls walking by, and the organist got a ripple of applause. The source was coming out again, carrying some sort of white box with a handle. As he got nearer to the taxi I could see it was a cardboard gift pack of six bottles of wine, with the sides cut away to make the labels visible. He went round to the passenger door, the side nearest us, and opened it, placed the box carefully in the footwell, then walked back round the front of the cab, climbed in and the vehicle started rolling. It was all over and done with in less than a minute.

Suzy's hands were securing the rolled-up top of her bag as the taxi melted into the traffic. 'So much for Muslims and alcohol, eh? Maybe it's Ribena.'

The Brits next door cheered and slapped the table. It wasn't Suzy's joke: Leeds had scored.

As we sat there and waited, I felt in my trouser pocket for the bike key. The target would be leaving for work soon. Even terrorists need to make money and have a cover story.

He was illuminated by the sign as he came out a couple of minutes later. He was a little early tonight. There was normally a fifteen-minute window after prayers before he set off. His white shirt was now tucked into a pair of black trousers, and he was wearing black patent leather shoes. He crossed the fence once more and headed to his Lite Ace, dodging the puddles in an attempt to keep his shoes clean.
