When the men started to throw beer at us on George Street, we took this as a signal to flee.

We charged down Castle Street, onto Princes Street, and up a side road in the West End. Just as we turned the corner, TPR flung a pistol back along the main road.

‘What did you do that for?’ I asked.

‘I don’t want to be caught in possession of SL’s gun,’ he replied.

‘So you ditch it on Princes Street?!!! Why didn’t you dump it in the canal, or the Forth, where your actions would not have been captured on CCTV? You are doomed’.
