Elspeth Durrant, a temperamental woman with a history of mental illness and suicide attempts, is found dead in her bed after taking a large number of pills and alcohol. Shortly before she had told her husband Frank that she was going to commit suicide. However the prosecution insist this was not a genuine suicide but a case of murder - he was tired of her behaviour and asphyxiated her by turning her face into her pillow while she was unconscious.
