Unravelling A Mystery, Columbo Style?

It seems that there may be more hedgehog activity in the making, this time either side of the entrance to our bridge.

Nigel was just passing, as a lorry arrived with another load of scrap and couldn't help but notice that it looked as if part of the wall beside it had turned blue overnight!

....... and on the other side .......

..... more was also emerging in white, even encroaching what had been our inaugural and original bridge hedgehog.

As to who these artists, so fond of hedgehogs and bridges are, the only potential clue Nigel could muster, in best Columbo style, was from the scattering of discarded McDonalds litter. However, with the said nearest fast food emporium 2 - 3 miles away, to eat their Big Mac, Nuggets and fries, while still warm and quaff their coke,  while carrying out more covert spraying, surely, he deduced, they must have a car or at best a bike?

As for the rest of the "art", as posted a couple of weeks ago, well, the hedgehog remains much the same.

The "tag" has been added to, filled in, but still, in Nigel's growing knowledgeable opinion, an undecipherable mess ......

....... although he mused, there was most likely to be some more highlights to come.

It's all looking to be yet another undercover and furtive hedgehog infused saga, as and when Nigel sees more, you, of course will be the first to know!
