How does a wife find out that her husband is a serial killer? Easy - she goes looking for batteries on a countertop in their garage - for some reason she notices some magazines underneath the countertop which she thinks are hers - however she finds some bondage mags in amongst the Women's Weekly's (because all serial killers are fans of women's magazines as we all know). Having seen these, for reasons best known to herself she drags out a load of cardboard boxes from beneath the counter and finds a "hidden compartment" in which he keeps all his trophies. SPOILERS FOLLOW so stop now if you don't want to know the ending.

Her husband finds out in a nano second but thinks there is no need for anything to change because it wasn't him it was the voice in his head what done it. She agrees, but has decided to kill him. How does she do this? Well, it's easy enough to push the rather small and stocky La Paglia over a three foot high stair railing isn't it and tell the police he has fallen down the stairs. The police will never notice the position of the body or the blood or the symptoms of suffocation or the totally inconsistent injuries. Then, enter a completely useless and irrelevant retired cop whose two scenes seem to exist to tell her 1. That he knows what she did and 2. That she did the right thing.

Absolute rubbish.
