Nick Warburton's play in which a kindly vicar appoints a lonely widower as safety officer in his church. But the favour backfires when he discovers the appointee is accident prone. The vicar, benign and reticent, refuses to tick off the geriatric. But the real trouble is that the parish community cannot help liking and promoting him. John, not the most inspiring of preachers, is soon eclipsed by his disciple, and finally makes a resolve: one of them will have to go! Director Peter Kavanagh (R)
