Just added 4 new pictures from Brenda's micro appearance on the DH
episode "The Ladies Who Lunch". And this is something I found about
the season finale from her own mouth:

--"Desperate Housewives' " Brenda Strong - who plays the dearly
departed narrator Mary Alice on the hit ABC nighttime soap - reports
even she still manages to be surprised by little nuggets being
revealed about her character's suicide in upcoming episodes. The
troupe is down to shooting the last segment for the season, and she
says, "There are certain aspects of my mystery that I had a
suspicion about, but there are other aspects that completely took
the rug out from under me ... you'll find out a lot more of the
mystery of why Mary Alice committed suicide and why Martha Huber
(the murdered nosy neighbor, played by Christine Estabrook) was
blackmailing her." Meanwhile, Strong says she'll get a decided
change of pace from the mayhem, murder and mystery of the posh,
upscale Wisteria Lane on "Housewives" this hiatus. "I shot
an epic drama about an early American pioneer family last summer
called 'The Work and the Glory,' and I'm embarking on two sequels
that we'll be doing back-to-back in Tennessee from April to June,"
says Strong. "I play the mother of the pioneer family. It's fun
because I get to wear corsets and no makeup, and I'm around teams of
mules and horse manure." Things certainly foreign to her "Desperate
Housewives" character, Mary Alice, quips Strong, "although I'm sure
she fertilized her garden."
