Murder Behind The Curtain(2011)

The 90-year-old mystery writer Lydia Walliser is suffering from writer’s block. Although she presents herself to the public as witty and cosmopolitan, her family bears the brunt of her more abhorrent traits. For Nick, her grandson whom she grudgingly accommodates for the weekend, it means: no mobile phone, no TV, no noise. Nick fears that these might be the worst days of his life. But then he notices strange things happening at the house next door and may have even witnessed a murder. When he and his grandmother begin to investigate, they embark on the adventure of the lives.
