Deviant Behavior — Earl Emerson

Seventeen-year-old Todd Steeb has been missing for eight days when his wealthy parents hire Seattle private eye Thomas Black to investigate. Faith Steeb is worried by her son's obsession with suicide, though her husband dismisses it as a youthful "deviance." Either way, ex-cop Black and his lawyer friend Kathy Birchfield aren't exactly thrilled: runaway kids are a dime a dozen.

It's a weird case that keeps getting weirder, as Black discovers forgotten crime, buried treasure, possible murder, and enough "deviant" behavior to blow Seattle off the map.
