Dave Robicheaux is a man driven by his constant battle with alcoholism; by memories of his past as a detective on the New Orleans police force; by his need for order; by his obsession with the seedy, aberrant side of New Orleans life. Trying to put his own life together again, Dave has married Annie and now runs a small fishing rental business in the Louisiana bayou. When he and Annie witness the crash of a small plane, in which four people, obviously illegal aliens die, and only a little girl survives, Robicheaux is drawn to the trail of a network of crimes that suggests a Central American dope-running ring operated with the connivance of federal agents. Violence ensues, and Robicheaux, no stranger to tragedy, must confront it again when Annie becomes a victim. Haunted by guilt, deeply depressed, in constant danger, Robicheaux trusts no one, including the cops, for he knows that they too, are capable of skirting the law.
