An old villain is returning to Wisteria Lane next season: sinister widower Paul Young (Mark Moses), EW's Michael Ausiello reports.

Paul, who was married to the late Mary Alice, was last seen in season 3, serving out a sentence for a murder he didn't actually commit. (Although we know he was perfectly capable of offing nosy neighbor Martha Huber.)

Since leaving 'Housewives,' Moses has played Sterling Cooper ad man "Duck" Phillips on 'Mad Men.'

EW reports that Moses will be back on a "full-time basis" next season. Which means we might also see the return of his even creepier son, Zach, who is actually (in true soap opera fashion) the son of Mike Delfino (James Denton).

Tell us: Are you excited to see the return of Paul?
