A story of murder and mystery, love and sacrifice. Mark gives a lift to a woman thrown bound and naked from a car. Her story is bizarre but intriguing: her child cannot be her husband's, yet she had no lovers. Mark, a zoologist specializing in Kalahari lions, is pulled into increasingly violent situations until survival depends on solving the mystery. As in PRIMAL and CABALLITO, the innovative sexual science behind THE HITCHHIKER'S CHILD is real.
