Who is Conrad Hirst?

Is it Rodrigo Corral?

Glamazon says:
" British author Wignall (For the Dogs) successfully channels Robert Ludlum in this lean, muscular thriller with more than a few parallels to Ludlum's Jason Bourne series. Conrad Hirst, a remorseless European hit man burnt out by a life of violence, plans to walk away from the business by eliminating the only four people who know his identity. Of course, it isn't that simple."

mmmm....lean and muscular...
