Hercule Poirot is bored to tears and with three weeks since his last case, is worried that his little gray cells will stop working. Captain Hastings suggest a evening at the theater to see the latest murder mystery but even that doesn't help when Poirot finds the plot to be absurd. On their return home to Whitehaven Mansions, they learn that the new occupant of the flat two floors below Poirot's has been found shot. She had only moved in that very same day and was an unknown. Poirot puts his little gray cells to good use and assists Inspector Japp of Scotland Yard in identifying the murderer. Written by garykmcd

Yet another one of Poirot's best
1 May 2012 | by (United Kingdom) – See all my reviews

I have been a fan of Agatha Christie and Poirot for nearly a decade now. The Third Floor Flat has everything I love about the series in the first place. It is classily made, with splendid photography and scenery, and the music as always is hauntingly beautiful. The script is both clever and witty, and the story is one of the more simpler, more suspenseful and more compelling story lines of the entire series with so much happening and solved in such a short running time. The acting is as great as ever, with the four leads superb especially the definitive Poirot of David Suchet.

All in all, one of the best Poirots as well one of the better short story adaptations(third only perhaps to Wasp's Nest and The Chocolate Box). 9/10 Bethany Cox
