Séance On a Wet Afternoon is a very welcome thriller. It is modestly made and carefully localised, with a good nervy script by the director and more visual character than any English film of its kind for ages.

It stands by itself as not only a psychological suspense thriller but also a top-notch crime-and-detection tale and, above all, a horror film.

I found the film dull because its theatrical conception robbed me of involvement with the characters.

As a study in suspense, this film must surely be a kind of classic. It is also a perfect demonstration of the fact that the most effective suspense is invariably created in a low key and without any violence at all.
