Blonde Faith book by Walter Mosley

Easy Rawlins, L.A.'s most reluctant detective, comes home one day to find Easter, the daughter of his friend Chrismas Black, left on his doorstep. Easy knows that this could only mean that the ex-marine Black is probably dead, or will be soon. Easter's appearance is only the beginning, as Easy is immersed in a sea of problems. The love of his life is marrying another man and his friend Mouse is wanted for the murder of a father of 12. As he's searching for a clue to Christmas Black's whereabouts, two suspicious MPs hire him to find his friend Black on behalf of the U.S. Army. Easy's investigation brings him to Faith Laneer, a blonde woman with a dark past. As Easy begins to put the pieces together, he realizes that Black's dissappearance has its roots in Vietnam, and that Faith might be in a world of danger.
