Terence Rattigan's play, based on a true scandal, explores the impact on the Winslow family after 12-year old Ronnie is expelled from naval college, accused of stealing a postal order.

Central to the plot is Mr Winslow's unshakeable belief in his son's innocence.

He takes his family on a crusade to fight the Admiralty and hires a celebrated barrister.

Under the skilful direction of Jenny Gore, and in a superb setting, the players deftly portray the tensions within the family as its social credibility crumbles and financial hardship forces them to make sacrifices.

A fine supporting cast was headed by Bob Morton, who gave a measured, imperious performance as the defiant Arthur Winslow.

Thomas Browne as Ronnie was excellent in his first lead role.

There are good performances and many fine moments: where Ronnie is confronted by his father and urged to tell the truth is especially poignant.

Jackie Reed plays the wife taken to breaking point.

Sarah-Jane Price convinces as Catherine, the daughter forced to choose between ending her betrothal to John, and supporting her father's doggedness.

A packed audience ensured justice was done to this fine production, which runs until Saturday.
