Cavanagh has touched on a number of themes in his books. In Two Kinds of Stranger, he looks at a TikToker who has shared so much of her life online that she’s become an easy target for a criminal mastermind.
In his latest book, One Of Us is Guilty, we meet the billionaire Vanderpool family and are immersed in a gruesome murder.
Patrick Vanderpool, who is running for governor, and his wife Vanessa are both in the firing line for the murder but Patrick’s father Julian controls half of New York so will anyone really have to pay?
Cavanagh said he wanted to look at extreme power and wealth in America the influence of multi billionaires.
“I write about law and a lawyer, and increasingly these days, laws don’t matter to some people,” he said.
He is critical of AI companies.
“That entire technology is almost based entirely on piracy. They have scraped millions of books and the government’s doing nothing.
“It’s almost the more powerful you are, the more you can get away with.”
For Cavanagh, this is a world away from his working class upbringing in Belfast.
He plans to take a break from Eddie Flynn for now, he has a standalone book in mind and has been asked by the Conan Doyle estate to write a short Sherlock Holmes story for a collection in the Autumn.
But he wants to reassure fans that Eddie Flynn will be back and hasn’t been beaten yet.
