Jessica (Angela Lansbury) is back in London, there to attend the opening night of a play based on one of her novel's. The play's producer (Robin Sachs) has a reputation for ruthlessness and duplicity, so it really surprises no one when he is murdered. Nor can anyone be surprised when Jessica (Angela Lansbury) takes it upon herself to prove that the play's leading lady (Jean Marsh) is not the murderer. ~ Hal Erickson, Rovi
