Once he had dreamed up the Easy Rawlins series, with its colored-coded titles and suave protagonist, Walter Mosley could have coasted for the rest of his life. Instead he delved into impressionistic fiction (RL's Dream) and sci-fi (Blue Light)--and came up with his own variant on Ellison's invisible man, a forbidding ex-con named Socrates Fortlow. The author first introduced this inner-city philosopher in Always Outnumbered, Always Outgunned, allowing him to vault one ethical hurdle after another. Now Socrates returns in Walkin' the Dog, still operating out of his tiny Watts apartment, still figuring precisely what to make of his freedom. Like his dog, Killer--a spirited mutt who's missing his two hind legs--Socrates has to contend with a number of severe handicaps.
