Paulo Ribeiro Neto’s review published on Letterboxd :
Ok, so this might just be one of the most British films I have ever seen... Jokes aside, Hitchcock was truly one of the greatest directors and it is really interesting to see his marks on one of his early works, in a point when he was still establishing his career. The mystery surrounding the disappearance mentioned in the title is great and very tied up together, giving a good pace to the story. Some elements could have been better explained and/or developed, especially in regards to the more vile characters and their intentions. Despite that, no one can deny that it is a very entertaining movie and I loved to watch it!
