Eye of Death - S2.E13

An antiques collector, Atticus Rook, makes a fortune selling new antiques from the Civil War era. It turns out that they are "as-new": by fueling a cursed "magic lantern" with the blood of a victim, he can travel back in time through a slide of wherever he wants to go, until the lantern "fuel" burns out in three hours. Ryan and Micki follow, but Ryan is captured as a spy trying to get close to Lee (whose sword Rook is trying to grab). A local woman, Abigail, helps Ryan only to be killed by Atticus. Ultimately Micki helps Ryan to escape, and they go back to the present and blow out the lamp... just as Rook emerges behind them, dying a particularly gruesome death caught partway in a wall where the image was projected.
