Air Date: September 13, 1970 Written by: John Hawkins Directed by: William Wiard
Guest Stars: Angel Tompkins (Janie Lund), Phil Brown (Wade Tucker), Ray Teal (Sheriff Roy Coffee), Bing Russell (Deputy Clem Foster)
An arsonist is on the loose in Virginia City and it happens to be Clem's fiancé. Roy's job is on the line when the fires don't stop.
Trivia: This episode featured the recurring characters of Clem Foster and Roy Coffee. Season 12 marked the beginning of the series being shot at Warner Brothers, the first 11 seasons being filmed at Paramount Studios. This change resulted in the burning of the 'old' Virginia City and the introduction of the 'new' Virginia City in this episode, since the series was being shot in a different studio.
Season 12 also brought change to the opening cast credits, as the long-running ride up scene was replaced with individual action shots of the main characters. Also, the now famous watercolors that ran with the end credits would be seen for the last time in season 12. David Rose also scored new title music that started with this season.
