The Last Detective — Robert Crais

P.I. Elvis Cole's relationship with attorney Lucy Chenier is strained. Then the unthinkable happens. While Lucy is away on business and her ten-year-old son Ben is staying with Elvis, the boy vanishes without a trace. When the kidnappers call, it's not for ransom, but for a promise to punish Cole for past sins he claims he didn't commit. With the LAPD wrestling over the case, and the boy's estranged father attempting to take control of the investigation, Cole vows to find Ben first. But Cole's partner, Joe Pike, knows more about this case than he has said. Pike lives in a world where dangerous men commit crimes beyond all reckoning. Now, one of those men is alive and well in L.A.--and calling Elvis Cole to war. . . .
