When a Buenos Aires industrialist is found dead at his home in Marivillosa, the novelist Nurit Iscar (nicknamed Betty Boo due to her apparent similarities to cartoon ingenue Betty Boop) is contracted to cover the story. Soon Nurit realises that she is falling in love with the man she has teamed up with to investigate the murder, which complicates matters deliciously. The murder is clearly no random crime. Five members of the Argentine industrial elite, who all went to the same boarding-school, have died. Not everyone, though, is keen on this link coming to light.
