Poirot doesn’t have to go far for this week’s case as one Ernestine Grant gets murdered in the flat two floors below less than 24 hours after moving in. Also under investigation by Chris and Pip: the physics of antisocial waltzing; plays within plays; using street magic to get other people to huff ethyl chloride.

Expect a new episode of Little Grey Cells every week, although it might not go up on the same day each time. Enjoy! We hope you come to admire Christie’s manic pixie dream detective just as we have.
