No, really, with good cause this time. We were weeding the greenhouse and this is what we found -
I think he lives under the paving slabs of the greenhouse path - they are laid on bricks and there is quite a gap. I saw him (or her of course) a couple of years ago in the greenhouse and he slid unhurriedly underground then. I went in excitedly, describing a grass snake over two feet long and people were politely pleased for me, but I suspect they thought I might be exaggerating. Now I have proof however, for this skin is fully three feet.
The full-length photo isn't great, I'm afraid, but you get the idea.
