The story is simple (I will not give away even an iota of what it is about) and involves mainly two characters... well, MAINLY. A typical Dahl-ian touch, comprising of suspense coupled with dry humour - all that makes a perfect concoct for Hitchcock to hit a home run !!!
Hitchcock-Dahl combination works very well, and I suggest that if you already haven't done so, try catching the other shorts of this master combination - The Man from the South, Lamb to the Slaughter, Mrs. Bixby and the Colonel's Coat !
Two thumbs up !!
