We're all working really hard to get ready for our Oct. 3rd premiere. We have several episodes completed and are continuing to put new ones in the can. We're also almost done writing our Ghost Whisperer Spirit Guide, which will be in stores Nov. 1. We think you'll really enjoy all the fascinating details it contains about the GW world.

Tonight, "Pater Familias"/Episode 318 airs. This is the Season 4 finale, so it answers a ton of the mysteries brought up throughout the years but also shakes up some new ones to solve next season. The episode was written and directed by series creator John Gray. It features Martin Donovan ( Weeds) and Anne Archer ( Fatal Attraction), and guest stars Corin Nemec ( Stargate SG-1) and Kirk B.R. Woller ( Boston Legal).

Have you checked out our behind-the-scenes blog lately? The GW digital media is hard at work letting you in on on-set secrets.

As always, thanks for tuning in, and we'll see you next week.

Kim & Ian
