One day in the late 1990s, I was sitting in work in Kirkdale, Liverpool when my boss asked if I could run a job down to a printers in Liverpool City Centre. It was a nice, sunny day outside so I jumped at the opportunity of getting out of the stuffy office I was sitting in. I got in my car and set off for the city centre. During the journey I had the radio on and I was listening to Radio City who had an author in the studio by the name of Tom Slemen. Tom had just released a book about ghosts who haunt Liverpool and he was regaling the tale of William MacKenzie.
