In the ending, however, we learned that Mark had been put on this list by mistake. However, the working relationship between Osbourne and Jessie soured, leading to him murdering her, but not before she wrote a list of everyone mentioned to the fortune tellers-the list that gets Mark Easterbrook (Rufus Sewell) involved in the case after he appears on it. The thallium is fairly untraceable, so it seems as if they have died of natural causes after a relative payed a visit to a group of women thought to be witches, making it seems as if they had died of a curse. Then, he would disguise himself as a workman and go to the victims' houses, where he would slip the poising thallium into food, cosmetics or their water supply. Rufus Sewell and Kaya Scodelario in 'The Pale Horse' Amazon Prime Video Before she died, it was Jessie's job to listen to these conversations and get all the details Osbourne needed to commit the murders. He instructed those who replied to visit the fortune tellers of Much Deeping in The Pale Horse pub, where they would discuss the relative they wanted to get rid of. The scheme went like this: Osbourne researched a number of people who stood to gain from the death of their rich or interfering relatives, then contacted them with an offer to have them killed in a way that would not implicate them. Zachary Osbourne (Bertie Carvel), the seemingly mild-mannered pharmacist had been working on a scheme to become an assassin for hire, and had hoped to get away with it by making everyone believe people's were dying of witches' curses. Who is the murderer in The Pale Horse?īefore things get supernatural, however, we get a rational explanation as to who has been killing all the people on Jesse Davis' (played by Madeleine Bowyer) list. However, at the end of the series, it is suggested that something supernatural may have gone on after all.

Toward the end of the mini-series, based on the Agatha Christie novel of the same name, viewers think that they are finally getting a rational explanation for a spate of killing that people think are being committed by witches.

The Pale Horse is now streaming on Amazon Prime Video after airing on the BBC in the UK in February.
