Toxin is the ninth episode of the second season. It was released on 25 November 2005.

When lives are lost and more are threatened by product tampering, Don Eppes and his team must head up into the hills to talk to a man with the community, though not the law, on his side, and no reason to be helpful. They run into Ian Edgerton, who has a mission of his own, which happens to dove-tail.


  • A poisonous substance produced within living cells or organisms. Etymologically, this derives from the Ancient Greek 'tokson' meaning 'bow' (as in archery), the favored way to deliver a poison in battle.
