Dir: Bryan Forbes
Starring: Richard Attenborough and Nanette Newman
An unstable medium convinces her husband to kidnap a child so that she can help the police solve the crime and achieve renown for her abilities
This intelligent and absorbing drama features a lengthy suspense scene filmed on the London Underground. Both Leicester Square and Piccadilly Circus stations feature along with a scene filmed onboard 1962-built Central Line stock (identifiable through car No.9165). Although neither station is on the Central Line, the 1962-built stock occasionally worked on the Piccadilly Line services, hence their appearance at the aforementioned stations.
