Although she was punished as his accomplice, Hannah was found not guilty of participating in the actual murders.

But was she really innocent? Dexter doesn't think so, and by the looks of these stills from upcoming episodes, Deb ( Jennifer Carpenter) has her own suspicions as well.

We'll also meet true-crime writer Sal Price ( Santiago Cabrera), who penned a book, "Love on the Run," about Hannah and Wayne's crime spree.

Has Dexter found another killer girlfriend? How will Hannah affect the Morgan siblings' fragile relationship?

"Dexter" airs Sundays at 9 p.m. on Showtime.
