The Oxfordshire-based writer first thought about the story when he was 17 and initially wanted to write a comedy play not a murder mystery to be performed by himself and friends.
He stopped writing for a short time while at university. In 2018 he decided to start writing again, this time, it would be a novel.
The 28-year-old said: “I dug out all the old notes I wrote when I was 17 and spent about six months doing research into the setting and revisiting the story.
“Then I started writing it in Summer and finished the first draft in November 2019."
He wrote A Fatal Corssing during his free time while working a nine-to-five job at a PR agency.
He said: “It’s a dream come true. I thought if it doesn’t get published, that’s ok. It is something I’m doing for myself, for fun.”
