With Elvis Cole and Joe Pike, Robert Crais created a classic crime-fighting duo. Elvis is the all-around good guy who who has mad people skills. Elvis reminds me of Archie Goodwin in the Nero Wolfe novels by Rex Stout and Dr. Watson in the Sherlock Holmes stories.
Joe Pike is the eccentric genius who has almost no social skills. He rarely speaks. His only facial expression is when the corner of his mouth twitches. Since Crais's books are set in twenty-first-century America, Joe Pike's genius is for violence. He has elite military training and experience as a mercenary. Unlike Nero, Sherlock, or Hercule, he does not solve the crime by deduction.
Also as in other series, the good guy is the storyteller. Like Dr. Watson and Archie Goodwin, Elvis Cole tells us how he and his friend caught the bad guys. This lets readers imagine what life would be like if their best friend was the smartest guy in the room or, in the instance of Joe Pike, the badest.
Robert Crais's latest novel, A Dangerous Man, drops the good-guy narrator in favor of multiple points of view. Elvis still narrates the chapters in which he takes the lead. When Joe or the bad guys take the lead, their chapters are narrated in the third person. Their actions are not filtered through Elvis's point of view.
I would prefer having Elvis tell me the story. It will be interesting to see what Crais does in the next book.
