S13:E03 - Blood on the Saddle

Ford Florey is a town with a Wild West Society and many grudges. During a Wild West show at the local faire, the witch on the 'Dunk the Witch' stall is well and truly dunked but laughter soon turns to horror when she doesn't get up and the water in the tank starts to turn red. Barnaby and Jones need to be quick on the draw to track down the murderer, and soon begin to wonder whether a dispute over land was the motive, or something far more sinister, especially when more people are killed, with methods linked to the Wild West.
