A husband stabbed his wife in the heart as she tried to break off their marriage, a court heard.
Heather Arthur had finally decided to leave her partner of 30 years, Mark Arthur, jurors were told.
But when she broke the news one morning last April at their home in Gosforth, Newcastle. Arthur stabbed her once in the chest, piercing her heart.
After killing Mrs Arthur, Arthur went to his doctor’s surgery nearby wearing boxer shorts and a top, bursting in on his GP and saying he had hurt his wife.
The 50-year-old has pleaded guilty to manslaughter but denies murder on the grounds of loss of control.
However prosecutors say he had known for some time the marriage was on the rocks and that Mrs Arthur wanted to separate.
Mark Giuliani, prosecuting at Newcastle Crown Court, told jurors: “She was exercising control over her life and told him it was definitely over and he didn’t like it and he stabbed her.
“The Crown’s case is this was not loss of control.
“Relationships break down every day but people don’t end up lying in a pool of blood.
“That is not a reasonable response to being told something you already had good knowledge of and well knew.”
The court heard the couple met at university in London and had been together for 30 years and married for around 10 years.
Mrs Arthur, who used to work for British Airways, thought the relationship had run its course and had talked to her husband about splitting.
Jurors were told she was a talented jazz singer and had grown close to the saxophonist in her band, Paul Gowland.
The court heard on the day before her death, Mrs Arthur had agreed to have one last family day out with Arthur.
The next morning, Monday April 29, she did the school run, called at Sainsbury’s then went home around 9.15am.
Only Arthur knows exactly what happened inside their home on Woodbine Road, Gosforth, when she got back.
He had an appointment at the doctors at 11.30 but turned up half an hour early without any trousers on.
Arthur went to the room of his GP, who was in with a patient, opening the door and telling her he had hurt his wife.
When officers got to the couple’s home they found Mrs Arthur lying dead in a pool of blood in the study at the back of the house, next to her husband’s desk.
Police untied a tightly knotted scarf round her neck, revealing a knife sticking out of her chest.
Arthur, who ran his own IT business, admitted manslaughter at an earlier hearing but denies murder.
The trial continues today.
