On last week's Mysteries of Laura, all the cops except Laura (Debra Messing) believed that Jon Dunham (Jerry O'Connell) killed his cosmetics magnate father and then blew himself up with a homemade bomb inside of his office building. Case closed.
But Laura found out that Jon was still alive when he popped out of her bedroom closet with a gun pointed at her. Now Laura's a hostage in her own home, and Jon didn't only make one bomb.
