Bertie Carvel as Zachariah Osbourne

In the novel The Pale Horse, Zachariah Osbourne is a pharmacist. He has a pharmacy on the corner of Barton Street in London. Osbourne told police he saw a distinctive looking man following Father Gorman shortly before he was beaten to death. Partway through the story, he retired as a pharmacist and moved to a house in Bournemouth which he named Everest. From there he wrote to the police saying he had attended a village fete at Much Deeping and had met one Mr Venables fitting that description. The police later told him that Venables was disabled so couldn't have been the attacker, but Zachariah Osbourne tried to give plausible explanations as to how Venables could have faked his disability.


He used the women at The Pale Horse, Mr Bradley and Customers' Reactions Classified to hide his actions. He was actually the murderer of the case and the person behind the "murder-for-payment" scheme which Jessie Davis had witnessed, and had confessed to Father Gorman.
