Twice in the last ten years, I have seen what is believed to have been a Black Panther running loose.
The first time I was on a train, when another passenger saw it and remarked how it looked like a Very Large black cat, as it was way not only too small for one, but also too fast for it to have been a horse.
The second time was a matter of months back, when a creature of similar description ran across the road ahead of me one night while on my way home from Model Railway Club.
