Charles Oldbury died in the bathroom of the old people's home where he lived. Dr. Fulmer who attended the scene thought he had suffered a heart attack and then drowned in the bath; she tried to resuscitate him without success. However the owners of the home - Margaret and Kenneth Povey - are now on trial accused of his murder and of defrauding his estate of £30 000 with the aid of convicted solicitor's clerk Leonard Saxton. The prosecution claim that they fabricated a change to his will for their benefit and then killed him in the bath, trying to make his death appear to be one of drowning. Both defendants deny all charges. They insist the change to the will was genuine and Mr. Oldbury's death was a tragic accident.
