He didn't like being labelled a crime fiction writer. He had major issues with it.
I agree with that. Higgins was an intellectual and, as you know, a former prosecutor. I'm sure it drove him nuts that people identified him more with the criminal characters that he created, than with the academic that he was.
Still, a great writer who died way too young.
