Evan Sherman was the husband of Helen Sherman and the leader of the cannibalistic Brynblaidd villagers. He was also Huw's uncle. During Torchwood Three's investigation into the villagers, Evan was briefly captured by Owen Harper, but was released by Huw and took Owen and Toshiko Sato captive.
Evan was eventually arrested by the police. In response to her demands to account for his actions, he told Gwen Cooper that killing and eating humans made him happy. (TV: Countrycide)
