Thalissa Teixeira

Henry Lloyd-Hughes (Killing Eve) and Thalissa Teixeira (Trigonometry) will join Lucy Hale (Pretty Little Liars) in the modern-day Faustian thriller following a trio of detectives attempting to solve a series of horrific murders.

Lloyd-Hughes stars as the newly reinstated DS Nathan Rose, with Teixeira playing his boss and best friend, DI Emily Baxter. Hale will play the unit’s newest recruit, DC Lake Edmunds.

Adapted from the novel of the same name, the psychological mini-series follows the forensic psychiatrist Dr Emma Robertson (Emily Watson) whose latest patient Connie Mortensen (Denise Gough) has been accused of a horrific crime yet claims she cannot remember a thing.

With a distinguished career meeting many high security patients, Dr Robertson is rarely shocked, but the psychiatrist is caught off guard by Connie as the pair develop a dangerously close relationship.

Throughout their sessions, Connie begins to anticipate and exploit her doctor’s deepest insecurities.
