The Wellspring of Death is the third episode of the first season of Agatha Raisin. The episode was written by Stewart Harcourt and directed by Paul Harrison. It aired June 21, 2016 on Sky One.

The episode is based on the Agatha Raisin story of the same name.


A village-wide squabble over the selling of water rights results in the death of the Parish Council Chairman. Agatha tries to put the matter out of her mind. But as the body count rises, she finds herself drawn into the fray.


Love, murder, danger - Agatha gets far more than she bargained for when Roy persuades her to take over the PR for a mineral water company that's looking to make a killing from Carsely's natural spring. As the villagers split over whether to allow the firm access to the water, they get a shock when Parish Council chairman Robert Struthers, the man with the deciding vote, is found dead in the spring.

As James decides to investigate with new girlfriend Mary Fortune, a jealous Agatha falls into the arms of suave bottled water boss Guy Freemont. Temporarily forgetting about James, Agatha is head over heels. But could he be too good to be true?

As a second body is found in the village, Agatha's competitive streak emerges and she enlists Gemma's help to try to beat James and Mary to the culprit. However, she makes a dangerous mistake when she decides to confront the killer alone.
