Desperate Housewives: What’s Katherine’s Secret?

So it seems that Katherine’s tasty lemon meringue pie isn’t the only closely guarded secret of the new (or should we say, returning) Wisteria Lane resident. Having already made a frenemy out of the neighborhood’s ruling domestic goddess Bree Hodge, it was only fitting on Sunday night’s episode that Bree would be the one to overhear a hint of something even more delicious than Katherine’s pie while snooping around for the recipe at the Mayfair residence.

Tell us: Why do you think Katherine left Wisteria Lane in a hurry all those years ago? And, why has she returned?
