Jennifer Beals Jennifer Beals

Fresh off her six-season run as The L Word's Bette, Jennifer Beals has signed on for a short-term role on Fox's freshman hit Lie to Me.

Beals will guest-star as Zoe Landau, the ex-wife of Tim Roth's Cal Lightman (and Emily's mother). When Zoe, an assistant U.S. Attorney, hires The Lightman Group to offer their expertise on an arson case, it becomes clear that she and Cal still carry a torch for each other.

Get it — arson case, torch? You can't get prose like that in just any news blog.

Beals' multi-episode arc, which was first reported on by EW's Ausiello, kicks off Wednesday, April 29.
