Wilson (Why Didn't They Ask Evans?)

Wilson is a non-canonical character created for the Agatha Christie's Marple adaptation Why Didn't They Ask Evans?. He is the butler of Sylvia Savage at her family home Castle Savage. Wilson is portrayed by Richard Briers.

Wilson has been in service with the family for a long time. He was already in the post when Sylvia was married to her first husband George Savage. He continued serving the family after George died and Sylvia married his brother Jack. As such he was privy to the family's dark secrets and was able to provide Miss Marple with valuable background information. However, as a loyal and faithful family retainer, he kept faith with his employer and did not reveal the secret service that he performed for Sylvia Savage: Sylvia was a drug addict and frequently needed injections of drugs supply by Dr Alec Nicholson. Wilson regularly injected them into Sylvia.

Wilson played a key role in the denouement. Together with Miss Marple and Sylvia's children, they set a trap for the Roger Bassington and Moira Nicholson. They caught the two in the act of trying to kill Sylvia. In the ensuing struggle with the would-be killers, Roger was shot by Tom Savage. Moira, wielding a syringe filled with deadly snake venom, continued to wrestle with Bobby Attfield. Wilson grabbed it from her hand and injected it into her, killing her with the same poison she intended to use on Sylvia.
