You'll see at least 4 Stargate Atlantis vets in this slow-burn show about solving crimes over a season's worth of shows (in the previous case's case, it was 2 seasons' worth of episodes). The show has been cancelled and brought back a few times, so hopefully the criminal will be revealed at the end of the season!
Jewel Staite, Ryan Robbins, and Ben Cotton have prominent recurring roles. Paul McGillion also has at least two episodes as a guest star.
And I'm still looking for quality screencaps of Jewel and now Paul for their Beyond the Event Horizon galleries on the main site at http://stargate-sg1-solutions.com/blog/actors/ .
