Brass Man (Agent Cormac)

From the Philip K. Dick Award nominee author of Cowl, an adrenaline-powered new SF adventure: Brass Man. Neal Asher returns to his trademark Polity future setting, in a sequel to Gridlinked, which SFRevu.com called "brilliant and audacious work, chock-full of cutting-edge ideas."
Ian Cormac, a legendary Earth Central Security agent, the James Bond of a wealthy future, is hunting an interstellar dragon, little knowing that, far away, his competition has resurrected an horrific killing machine named "Mr. Crane" to assist in a similar hunt, ecompassing whole star systems. Mr. Crane, the insane indestructible artificial man now in a new metal body, seeks to escape a bloody past he can neither forget nor truly remember. And he is on a collision course with Ian Cormac.
