Fiona Gray is charged with arson after setting fire to her estranged husband's house. As her children were in the house at the time, the defense are claiming diminished responsibility.

During Rick Gray's evidence he reveals that living with his wife was like living with a small child. Gilbert Brinsley, who worked at Coldwater Valley Arts Society, admits Fiona Gray instigated a sexual relationship with him.

Prosecuter John Lloyd dismissed claims that Fiona Gray was an automaton and unaware of her actions in burning down her husband's house. Taking the witness box she refuses to answer questions about her motivation in starting the fire.
