Dog wanted to roll in it. She was not permitted. I didn't know what it was and I didn't have a camera on me and it isn't easy to explain. Whatever it was (this is not fiction, incidentally, this is me on Widemouth Beach finding a sea monster) had a fleece skin and the S-bend body shape of a seven-foot slinky fish. Flesh seemed mammalian. Obvious explanation is that a sheep has tumbled from a cliff edged field and been remodelled by the sea. Can't work out how that sharky shape can be made of sheep. Mysterious: strange.
Shook my head and went for a stride in the waves, which were messy and cold.
Drove home my favourite way: with bare sandy feet.
Later when my feet were dry and zipped in boots I decided to get some mussels for tea, and on the way to the fish counter met one of my junior students. She has a twin brother, who looks much like her but is autistic and does not speak. I smiled at him and he reached out for a hug. This is a rare event, decidedly noteworthy. Mysterious: marvellous.
