I know. But if you think CS must have noticed the smell, then how come no one else noticed it? SH's interview was on the night before Tia's body was found, and some of the family were upstairs during the interview, including Tia's mum, I think. Therefore, if CS must have noticed the smell, surely the others must have done too? Even the criminologist didn't notice anything. That part is a total mystery to me. I don't know what kind of cleaning materials can mask a decomposing body for 8 days. It doesn't seem possible. Maybe there were fans upstairs (because of the heat) and that helped move the air around? I don't know.
