Underground

Adrienne Lockley's father was murdered during his police investigation of the disappearance of several runaway girls from a women's help centre. Sixteen years later, Adrienne receives a phone call from socialite Rebecca Kaber who tells her she knows who killed him. Before they can meet Rebecca is found dead. A year ago, Rebecca's husband fell from his boat. His body was never found. Are the deaths coincidental, or is there a connection underground?
