Paul Longworth thought he had committed the perfect crime.
He strangled his wife, Tina, with a rope and left her dangling from the banisters. He then left the scene of the crime, their home. He went to Southport Sailing Club, where he was the commodore, to celebrate his 37th birthday party.
Back at home, he left his two young children asleep in their beds, while their dead mother was downstairs. No one at the party suspected he had just committed murder.
On returning home, he called the police, alerted his neighbours to the death and told everyone Tina had committed suicide. At first detectives believed him.
As former detective – and role model for Prime Suspect‘s Jane Tennison – Jackie Malton says during the next edition of Murder by the Sea, ‘What makes this crime particularly unpleasant and horrific is that he risked that his two children could have got out of bed and found their mother, which would have traumatised them.’
The series, on CBS Reality, has so far dealt with psychopaths and gangsters. This episode is different. It explores a story of domestic abuse, about the darkness behind respectability and the cold-bloodedness of this killer.
Thought he was cleverer than the police
Like the other talking heads on this episode, I found it hard to work out how somebody, even a man in a failing marriage, could have had such a void of feelings inside.

‘He came across as very much an arrogant man, says Professor Mike Berry. ‘He thought he was cleverer than the police, he thought he was going to get away with it.’
To find out why he didn’t, watch Murder by the Sea on CBS Reality (Monday 18 June 10pm, Tuesday 19 June 2am, Sunday 24 June 9pm).
