Hitchcock wastes no time and from the very beginning of the film creates an extraordinary plot. Unusual both in itself and separately in the theme of comedy. That a murder takes place is no surprise, but who would have thought that within a few minutes there would be 7 people alternately bumping into a body lying in a clearing as witnesses. The setup is hilarious. Things will move very slowly from there, and the film will only introduce the characters and their connections to the murdered man. The real pleasure the director and the scriptwriters saved for the last half an hour, which in terms of black humor will give a head start to any "koens".
The scriptwriters are pleased with the fact that they wrote such funny lines for all the characters even 50 years later, and all the characters are so truthful in their remarks, in their jokes. The nice thing is that the detective element is completely removed from the movie, there is no hint, no tension, no nervousness for this or that character that he is not doing something. Everything develops slowly, the characters get to know each other, sometimes banter about the corpse, and only near the end does the humor completely come out of the movie and start running through your brain, there's no holding it back.
Of course, it's not without the melodramatic line inherent in all Hitchcock films, but it's so minor that it looks more like an artist's beautiful signature to his little diversion, a fascinating (if you don't count the first warm-up hour) black comedy.
