Margie Middleton is standing trial accused of bigamy. The prosecution allege that she went through a marriage ceremony to Colonel Middleton knowing that she was still married to her long estranged husband Patrick Delaney. However the defence argue that her marriage to Delaney was itself null and void because he was actually still married to Kathleen whom he claimed had been killed in an air raid during the Second World War.
