SPRIGHTLY SPINSTER gets invited to a weekend in the country with second cousin/uncle/vicar’s nephew/any number of landed gentry types. Death ensues, usually in the middle of the night in a thunderstorm in the library with the lead piping. Local coppers (who are all stupid) haven’t a clue. Old woman keeps own counsel and pesters her hosts for another barm cake. A few days pass. Someone else cops it. Old woman seen walking around village green/posh garden/reading newspaper and looking gnomic. Everyone gathers to find out the ending. Old woman discloses suspect’s name while sipping lime cordial. Local coppers strike heads in bemusement. Evil-doer led away. “Where you’re going, you’ll have no need for garden shears/sawn-off shotguns/tarot cards,” cackles local stupid inspector person. Old woman returns home to rest before being invited to nearby grand niece/sister-in-law/bellringer/tropical explorer tea party in the next episode. Tootling theme and line-drawings bring the curtain down.
