Love the series watch these episodes over and over again, but tonight 07/8 on Sundance watched how Houch wife died. I thought I saw her get killed from bomb righted into personal car that was geared for him. Saw a DVD in store for final episodes (15 ) before it is discontinued . None of the episodes I've seen has hinted of this, when are these episodes to be seen? Will there be any ads on TV about this? I was hopeing that Derrick would return.
