Private Investigator Ray Lovell is hired by a father to find his missing daughter, Rose. Complicating the case is the fact that the woman has been missing for seven years and her family and her husband’s family are mistrustful gypsies who seem determined to withhold information. No one has an answer as to why Rose would abandon her chronically ill child or how she, without friends or money, could disappear so completely, or why, for seven years, neither family has reported her missing. Half-gypsy himself, Lovell doggedly searches for the missing woman but the case is made more mysterious by a poisoning, a fire, a death and another disappearance. Lovell’s persistence finally pays off leading him to two shocking conclusions in The Invisible Ones.
