Do you only have a shower when you do out? Why should Sheila have had a shower?
I didn't say Sheila had a shower. I don't see why any of them had to have a shower that night. Why couldn't they have had a shower in the morning? If Jeremy went home at 10pm(?) why would he have a shower if he was only going to watch TV? If he's the killer, why would he have a shower that night?
Do you think that people only shower at night?
