Yes. The easiest method is to simply tell Mrs. Rockwell that her husband is cheating on her, which she will readily believe after a speech check.
You can also place the Lacy Underwear from the Simpson household on the desk in the basement, then tell Mrs. Rockwell that her husband is either cheating or he is a cross-dresser.
Finally, one can read Mrs. Rockwell's diary upstairs, which will indicate that she'd like to kill Mrs. Simpson. Take the Rolling Pin from kitchen in the Rockwell house and beat Mrs. Simpson to death with it, then tell Mr. Rockwell about it. ReapTheChaos 03:45, February 1, 2010 (UTC)
