William Scott, 27, had been through hell in the First World War trenches, but one thing kept him going: the thought that Betty Corbett would marry him when he got back home to Clunes Vennal, in Main Street, Ayr.

But on demob leave on JUNE 28th, 1919, Scott staggered back aghast when Betty said “no.” Furious, he slashed her throat and stood over her as she bled to death.

Two months later at Ayr High Court he was convicted of murder and sentenced to life. He was released in 1931 after serving 12 years.
