This movie leaves the audience a mystery of whether or not Andrew kills his wife. I kinda believe Andrew did it, cauz 1. when he says Dale Gabrielle is abroad, he is burning Gabrielle's passport with a crafty smile on his face. 2. He mentions Gabrielle's changing her name,and is god damn sure that she will never come back. 3.Since Gabrielle goes abroad,how come her clothes remain? Plus, the painting of her is slashed (probably by Andrew) 4.the basement could be the place to hide body if someone would argue that Andrew suffers acrophobia. Based on this assumption, I have to say: well,ron is a pyscho,he looks awful,plays awful and we see him kills people. But Andrew,he looks cool,plays cool,so I can hardly imagine he could kill. And that makes a real creepy pyscho.
