Beasts

I saw this at the age of 12 when it was broadcast for the first (and only) time. Two stories stick in my mind, Buddyboy, about a haunted Pool/Ghost Dolphin (memorable to me for a very well-endowed young lady removing her Bra!! ) But the story i remember most, the title of which i cant remember but concerned a plague of Rats, stealthily attacking people trapped in a country cottage.In the entire episode you never actually See a Rat! But it was done superbly. Always looked forward to seeing this show repeated, but never has been. It was a gem from Nigel Kneale, an Ace writer.
