Was looking at the bbc website earlier and spotted a story* about a "dangerous heffer" loose in Darlington. I read the whole thing, and the word "heffer" appeared several times.
Hm, I thought. I wonder if that's a regional spelling, or a farm term I am unfamiliar with. I looked it up on www.dictionary.com, and it doesn't exist.
Just checked the story again, and it now appears that a dangerous heifer is on the loose.
So, two deadly bovine assassins, one of them presumably in a brocade dressing gown and slippers, smoking a pipe.
