Here's what I wrote about it when I saw it last year:

Black comedy in which death is as overbearing as it would be in Vertigo, with Burks' cinematography bringing an autumnal reverence and the dialogue peppered with references back to the corpse causing problems; the difference is the matter-of-fact way in which everybody here goes about dealing with it. It should have been a lot funnier (especially with Edmund Gwenn, years after Hitchcock's The Skin Game) than it is, but the delivery is awkward for the most part. An interesting departure from material for which he was - and is - better known.
