This plot is similar to another in the Poirot series and actually, it's fairly easy to figure out. However, it's still well done and very entertaining.
Things aren't happy in Poirot's office. Miss Lemon has had it with her ancient typewriter and wants a new one. Though this is news to Poirot, both she and Hastings insist it has been mentioned several times before.
Now he can really forget about it, as he is summoned to meet a man named Farley, the King of Pies, at his manufacturing company. Farley is disturbed about a dream he has had repeatedly. In the dream, at an exact time, he removes a gun from his desk, walks to his window, and kills himself.
Poirot isn't much help and is dismissed by Farley. The next day, Farley is found dead under the circumstances he described. Poirot and Hastings then help Inspector Japp figure out what happened. In the end, the typewriter-seeking Miss Lemon gives Poirot the clue to the case.
A delightful episode that shows activity in Poirot's office with the wonderful Miss Lemon (Pauline Moran) and Hastings (Hugh Fraser), with Poirot at his absent-minded genius best.
Recommended, though not the best story.
