Having just read about a million pages of these threads to catch up (thanks for the tweets, everyone ... only took me, literally, about three hours to read it all), I would say that things to add to your great synopsis are:
- The brown towel that Suzanne was sunbathing on has never been found ... (one of the most important things imo )
- There was a bullet casing (staged? unstaged?) laying by Suzanne's side of the bed.
- Suzanne's spy pen was found concealed in a box of bras.
- One half-filled coffee cup sitting in kitchen, from who-knows-when.
