I too got caught up in this show also....I love terri hatcher and remember her from lois and clark...I thought nicolette's name was familiar but could not place....now I know why...knots landing was not not my favourite and I was a bit young at the time to like it......anywhooo.....back to the show.....I like that really nosy neighbour(don't know her name yet) but she is a real trip...she has practically figured out that the measuring cup belongs to the terri hatcher character....and she will find out what the new guy is up to before anyone else even suspects and she will probably find out what's in the box.....
as to the box well, I think it is a body...most likely a child...killed or died accidentally and then they kidnapped a child that is now the sun....I know that is out there on a limb....does anyone else have a theory...
as to the letter I think the wife wrote it to her husband or the son wrote it his parents....the narrator did mention during the digging up of the pool that the sound was familiar to her son when he was a baby(toddler..) again on the limb .. it will soon break ...so what do you think...
