I am trying to guess what's in the toy chest. The way he wrapped it (very carefully in plastic) makes me think it's something important like documents. Something that he might need later on for some reason. The only other big clue that I caught was that the boy had heard the sound of the digging when he was really young. So it was buried in their pool several years earlier. I think the old lady who is in everybody's business wrote the letter. And the plumber is in town because of something completely different than the suicide (or its cause). I think he's investigating something entirely different that we have yet to notice.
The "wives" were on Oprah this week. I think Oprah slipped and gave it away that Bree has a secret. I don't think the show has alluded to any secrets for her character yet, other than she's insanely "perfect."
Anyone else have guesses about what's coming up?
...and the moral of the story is, don't buy a weedwhacker when your lawn is dead!!!"
