John Kane is my Batman.
I grew up heavily influenced with the Dark Knight. I think it was the lack of special abilities that was the key for me. All he had was his training, his wits and his gadgets. I enjoyed the fact that he was called the detective. It meant he had to be observant and aware of what was going on around him.
I collected Detective comics for most of my childhood. As I grew older I stopped collecting. Then something amazing occurred, something that shifted the paradigm, at least for me-the graphic novel. I started collecting these graphic books, but one in particular stayed with me. The Dark Knight by Frank Miller(I still own it). Here was the Batman I was waiting for, darker, grittier, real, and older. For me it was Batman as he should have been all along.
This experience stayed with me and when I as thinking of a character for my John Kane novels it shaped my character. John is an older asset- retired. He is forced back into the life he left because of a special ability he possesses. An ability he thought was lost until people turn up dead, killed by someone with the same ability.
