I opened the envelope hesitantly and drew out the photographs, my heart beating in apprehension. I examined them for a few seconds, one by one.
"Is this it?" I asked, my voice rising in indignation.
"Yes," he said, "I photographed the whole thing. You had no idea I'd tailed you."
"And that's the best you can do...? You seriously expect me to pay you for these?"
He pushed his spectacles further up his nose and leered.
I went on: "Look, I'm sorry, but if you're going to try to blackmail me, I'll expect you to do a lot better that this. I mean, these are RUBBISH. I'm very disappointed. Not only is the framing total crap, but you can't even see anything happening. This could be anything - gnomes dancing round a mushroom - anything."
He blinked, started to laugh knowingly, then stopped abruptly.
