question: What is the first name of the person who is accused of murder?
context: The film concerns the residents of a large terraced house in London between Christmas 1938 and September 1939. Among them are the landlady, Mrs Vizzard (played by Joyce Carey), who is a widow and a believer in spiritualism; Mrs Josser, Mr Josser and their teenage daughter; the eccentric spiritualist medium Mr Squales; the colourful Connie Coke, the young motor mechanic Percy Boon and his mother.
  Percy is in love with the Jossers' daughter and turns to crime to raise money to impress her with, but he bungles a car theft and finds himself accused of murder. Mr Josser digs into his retirement fund to hire the boy a lawyer. Mr Squales testifies against Percy, but in the process exposes to his fiancée Mrs Vizzard the fakeness of his claims to be able to contact the dead and to predict the future.
  Percy is found guilty, but his neighbours rally to his defence. With the assistance of Mr Josser's staunchly socialist Uncle Henry they gather thousands of signatures on a petition to gain him a reprieve. At the end of the film Percy's supporters march through the rain to Parliament, only to discover just before their arrival that clemency has already been granted.
