Set in the country home of Freda and Robert Caplan, the action takes place at a dinner party gathering of friends, most of whom work for the same publishing company, owned by Freda's father.

The evening follows the familiar banter associated with such occasions - seemingly happily married couples trying to pair off singletons, sharing of gossip - all quite trivial.

Yet the presence of the inquisitive American visitor Maud Mockridge turns the conversation towards an examination of the past, of the recent death of Robert Caplan's brother Martin.

His death was determined by the coroner to have been a tragic case of suicide brought about by the humiliation of having been revealed as a thief of money from his own father. This is a finding that no one has sought to question - until now. And so the relationships between husband and wife, brother and sister, friend and admirer proceed to unravel and destruct as revelation leads to revelation, from which no one is exempt.

This is a brilliant piece of theatre written by Yorkshire's own J B Priestley 75 years ago as his first piece of theatrical writing. This play has not lost any of its drama over threequarters of a century.

In this particular production it is not just the writing and direction of Dangerous Corner' that mesmerises. Rarely is one treated to such tremendous performances from across an entire cast. To single out any particular performances is not to detract from the strength of the entire ensemble.

Mention must be made of Peter Amory (Chris Tate in Emmerdale') as the calculating Charles Stanton, who sees the fine equilibrium that he has created shattered by the evening's soul searching.

Also, special note must be made of Chloe Newsome (Vikki McDonald in Coronation Street') as the apparently cherubic and innocent Betty Whitehouse, a part that she plays with the confidence and conviction of a seasoned professional.

Finally, it would be wrong not to congratulate Jacqueline Roberts who gives a powerful and first class performance as the tormented Olwen Peel whose slip it is that triggers the entire collapse of the group's cosy circle. And what if she had not done so, what if she had not triggered the discussion - the final scene of the play shows us, the audience, how lucky we were that she did but how easily she might never have unleashed such tragic destruction.

Everything about Dangerous Corner is perfect - you are going to have to wait a long time to experience such a fantastic combination of plot, acting, design and direction as is currently playing at the Grand Theatre.
