It turned out that Mum, who had nipped out to her meditation group in Nevern, had become parted from her coat and in that coat pocket was her car key. Ah ha.
It also turned out that "we'll fetch you" actually meant "Maggie will fetch you". Ah ha ha.
I dragged myself out from underneath the dog, threw on my coat and valiantly charged out into the stormy night in my 4X4.
I splashed triumphantly into Nevern, to be greeted with the words, "have you got my spare car keys?" Oh
So I drove my parent back over the Preseli Hills through fog and rain and wind while she explained that her coat had inadvertently gone home (to a deepest darkest somewhere south of Lampeter) on the back of a gentleman who had mistaken her smart Berghaus waterproof with its pocketful of car keys and sensible torch for his moth-eaten coat which had the grand total of nothing in its scruffy pockets. Mum was wearing the latter (because it was raining) looking moth-eaten, scruffy and car key and torch-less.
We left Mum's car (according to her) tucked in neatly at the side of the road or (according to me) parked in the middle of the road blocking her hosts' car neatly in its driveway and causing a small obstruction to those negotiating the picturesque but narrow bridge over the river Nevern.
The night passed bringing more rain and the morning subsequently arrived with news from Mum's hosts that her car was parked near the river and the aforementioned river had just burst its banks. Ah.
We had visions of a little silver Hyundai Getz appearing on news reports bobbing down the river to the sea and causing a hazard to shipping.
So we splashed over the Preselis again, this time double-checking the presence of the spare key, passing through two floods and dodging others and successfully rescued the car from the clutches of the river Nevern.
The coat, the keys and the torch? Well they're still somewhere in the deepest darkest depths of the countryside south of Lampeter. The apologetic gentleman says he'll return them. Eventually. Case closed.
* Incidentally, Maggie isn't really short for Magatha, but I think it would suit my surname better if it was!
