After brilliant but socially inept DS Sean Stone ruins a police press conference, he's demoted from homicide to the Missing Persons Bureau. Will his lack of social graces get in the way of finding a missing teenager who frequents a pro-suicide message board?

Stone focuses on a new case, this time concerning Stephen Eli, a lawyer who disappeared from his family one year ago. Almost immediately, Stone is convinced he knows the criminal responsible: a serial killer already confined to a mental institution.
