Baxter is a supporting character and also the hidden male main antagonist of White Bear. He is portrayed by Michael Smiley.
Baxter first appears when Victoria and Jem are being chased by the Hunters. Baxter is also unaffected by the signal, but drives them to a forest and holds them at gunpoint. Although Jem escapes, Victoria is tied to a tree and about to be tortured until Jem returns and kills Baxter.
Later, Baxter is revealed to have survived, as he straps Victoria into a chair and explains everything: the girl Victoria assumed to be her daughter was actually a six-year-old schoolgirl named Jemima Sykes, whom Victoria and her fiancé, Iain Rannoch (the man from the photographs), abducted a few miles from her home. After taking her to a nearby forest, Iain tortured and killed Jemima while Victoria recorded his actions on her mobile phone. The 'White Bear', originally the victim's teddy, was a symbol of the nationwide search and murder investigation, while the symbol on the screens and on the hunter's mask was identical to the tattoo that identified Victoria's fiancé (who committed suicide in his cell before the trial). Having tearfully pleaded guilty and insisting she was 'under Iain's spell', Victoria was given a sentence the judge described as 'proportionate and considered' – to undergo this mob-recorded, poetic justice every day.
Victoria, who still has no clear memory of these events, is driven back to the compound past a crowd baying for her blood (under encouragement from the staff) and returned to the room where she woke up. She is placed back in the bedroom chair by Baxter. As she watches footage of Jemima, Baxter places electrodes on her head, wiping Victoria's memory of the day's events as she screams in agony. As Baxter leaves the compound to the sound of Victoria's screams, he takes out a black pen and crosses off 18 October from the calendar; ready for Victoria to relive the same events the next day.
