Teressa Lidiard

Teressa Lidiard is a villainess from the 2016 Lifetime film, Undercover Wife (alternately titled, Not With His Wife).

She was played by Lucia Walters.

Teressa Lidiard is an agent with the FBI, who was on the case regarding white collar criminal Collin Murphy. As revealed later on, Teressa is a villainous mole on Murphy's payroll, and she made attempts to set up Josh Bolland (a murdered FBI agent) as a corrupt official working for Murphy.

Monica, Josh's widow (who was investigating Murphy and her husband's murder), was approached by Teressa at her home, with the false claim that she was sent by fellow agent Isaac Nolan to pick up Monica. She drove Monica to what she claimed was a safehouse, all while attempting to convince Monica that Isaac was working for Murphy. The "safehouse" was actually a hideout where Murphy was waiting for Monica, and it was at that moment that Teressa pointed her gun at Monica, revealing herself as the mole. The duo set out on killing Monica, but they were stopped by Isaac and the FBI, who arrested both of them.
