Erika is supposed to be the ruthless shrewd real estate agent a la Heather Locklear in Melrose Place. Soap premieres April 9. It will move into the 9 p.m. Wednesday slot. The soap centers on young couples on the fast track to fame and fortune, romance and heartache, and scandal and ruin. If "Palisades" does well in a scheduled six-week run, Fox will run new episodes in the summer.
