Based on American writer George Bellak's play The Trouble-Makers, about the murder of a campus newspaper editor by his fellow students and the ensuing 'witch hunt'.
Many sources date Bellak's play to 1956, but it was first performed in London in 1952 (see, for example, The Times, 18 August 1952, p.8).
Aired on BBC radio on 31 January 1953.
