But their chemistry begins to falter when Violet becomes irritated and then terrorized by a series of anonymous phone calls. He's ordered to tell no one and to follow instructions, or else the hooded figure he sees on the home's security cameras will kill Violet's young son and the nanny's sister. Violet must do exactly as she's told, or everyone she loves will die. Her unseen tormentor's final order? Kill Henry.
