A film that will remind you that a Dimbleby has always been on the BBC as Richard Dimbleby plays himself as a member of the Twenty Questions radio panel. The panel receive a series of anonymous clues that lead to murder.
A journalist Bob Beacham (Robert Beatty) realises that a question sent by a listener regarding Riki-tiki-tavi is somehow linked to the death next day of a man with a name similar to it.
Along with a fellow journalist Mary Game (Rona Anderson) they look for similar clues in the next edition of the radio program as they figure that a pattern is developing.
It is never explained why the murderer has gone to elaborate lengths to the taunt the police but they seem to be more interested in fitting up an Indian manservant called Mohammed Ali.
All through the film you get comments on the case by two BBC workers on the reception of the radio show.
There is a lot of casual sexism in the film, yet it is a rather amusing, dated and diverting thriller.
