Mark Wylde is a fictional character from the British ITV soap opera, Emmerdale, played by Maxwell Caulfield. He made his first appearance on 15 January 2009 and departed on 14 January 2010. In early December 2009, it was announced that Caulfield had quit the show and would depart shortly. Producers promised a "stunning exit storyline" which would see a who-dunnit type storyline in which Mark would be killed. Mark was murdered by his wife, Natasha Wylde, on-screen (although only the audience knew of Natasha's guilt) on 14 January 2010. The murder storyline saw the revelation of Mark and Faye's affair, that Mark was Ryan's biological father (meaning that he was Maisie's brother), and Natasha found out about Mark's cheating, giving them all motives for murder. The storyline reached its climax in mid-October, which saw Natasha confess to Mark's killing and sentenced to 21 years imprisonment and Ryan leaving the village for a fresh start.
