1x9 - The Agatha Christie Hour

Jane Cleveland is out of work and owes rent on her London flat. When she is offered the role of 'double' to the Grand Duchess Olga, the adventurous Jane accepts with alacrity, especially as the financial renumeration for the role is lucrative. However, all is not as it seems ... Jane is thrown into a world of intrigue, double-dealing, jewel robberies, and deceit. It is perhaps as well that Jane's new boyfriend is attending Hendon Police College and has an observant and quick eye.
