I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Shaitani Ilaaka Movie plot: A grotesque brougham stops in a dark forest and its cowled driver, Lalbai the sorceress, beckons to the bewitched passenger, a newly wed bride. Lalbai leads the bride to the shaitani ilaaka (devil's domain) where she is roused from her spell. The bride is sacrificed, screaming and kicking, at the altar of her aka (the Shaitan, or great devil). Shaitan is an ancient and fearsome demon. Years ago, he roamed free and indiscriminately terrorized the local townsfolk. But he was ultimately defeated, reduced to a formless soul, and held, by a magic charm, to remain imprisoned forever within the shaitani ilaaka. Lalbai brings him a fresh bride every Amavasya night. Shaitan consumes the blood of this bride, and grows stronger with each offering, until he can break the charm, restore all his evil powers and ravage the world again. At the affluent home of rich industrialist Thakur, he has a wife, Roma, and their six-year old daughter, Anju. They have retained a governess, Shalaka, for Anju. Anju seems to be a happy child with one exception. She experiences strange convulsions and horrible nightmares every Amavasya night. Thakur decides to bring her to Dr. Yograj, a medical man who has attained Siddhi through rigorous spiritual training. Dr. Yograj examines Anju from a medical standpoint, but also notices strange telekinetic events when Anju is in his office. Later, at the home, he observes phenomena that strongly indicate a poltergeist. When he talks to Shalaka, she firmly snubs him. (Unbeknownst to the family however, Shalaka practices voodoo with Anju as the target.) Dr. Yograj refers Thakur to a famed Tantrik Baba (wise man), recently returned from Tibet after an extended spiritual course, for help. Baba visits the home, inspects Anju's room, and immediately identifies it as the work of a malevolent aatma (soul). He advises Roma to remove Anju from the home, take her far away, and have her recuperate. This must be done at the brahmakaal (good time, when the powers of evil are weakest). Anju's boyfriend Deepak and... My question: Lalbai infiltrated Thakur's household as what?
The answer to this question is:
A governess
