'Desperate Housewives' sneak peek: Trick or freak?

October 29, 2010 5:18 PM ET

It's Halloween on Wisteria Lane and Renee (played by Vanessa Williams) is throwing a big party for all the "Desperate Housewives," but apparently there's more drama to be found outside of which costumes they'll be wearing.

Lynette (Felicity Huffman) grows increasingly worried about her mother-in-law's memory lapses. Gaby (Eva Longoria-Parker) may be heading for choppy waters as Juanita (Madison De La Garza) begins to feel something may be up. Mike (James Denton) isn't taking the news of Susan's (Teri Hatcher) sexy internet side gig very well and she has had quite enough with Paul's (Mark Moses) blackmailing of her. Plus, Bree (Marcia Cross) has found something worrisome in Keith's (Brian Austin Green) past and feels she needs to get to the bottom of things.
