I added to my fortune whenever I paid a visit to the cash dispenser just outside Edinburgh’s Balmoral Hotel. Here each morning on my way to work, I pretended to make a transaction. In reality, I was picking up wads of used bank notes, then stuffing them into my satchel.

I had no idea who was supplying the cash. I would have continued to collect it until TPR pointed out that my dodgy dealings were probably being recorded on CCTV, and that I would soon be arrested.
