Though never mentioned in the film, the plot suggests a lot of sexual motivation, especially on behalf of the husband.

A man tries to murder another man by firing a gun at him as the other man tries to evade him.

The sculptor character seems to have a bit of an alcohol abuse problem as he is fairly inconsistent and sometimes incoherent.

A lot of suspicious deaths happen around one of the male characters in the film, which builds the tension towards the grand finale. The fate of the antagonist is left to the very end; he fakes his suicide and his true fate is left to the very end of the film.
