The newscaster names him as Mikhail Morozov but secret service agencies around the world know him as Margaret Rotheram's former favourite, Michael Frost. He's been abducted by terrorists. Urgent meetings are convened around the globe to discuss what to do next, nobody wants what's in Frost's head to come out. Not everybody survives those meetings... The story delves into the murky family history of Margaret Rotheram. Her father was killed while working as a spy for British Military Intelligence when she was still an infant. She is adopted by a neurotic family and given a new identity. As a grown up, Margaret comes to the attention of dark forces who are determined to recruit her. Michael Frost, mute until the age of three, speaks his first words. He sees visions of demons that until now he hasn't been able to tell anybody about. Being different to most other children, Michael is routinely bullied at school. Despite his many obstacles he does well in his studies and leaves school to join the army. Posted to W. Germany, Michael attracts the wrong type of attention and becomes in danger of his life. Margaret and Michael meet under perilous circumstances while she is planning to steal Soviet Missiles. Margaret seems to have lost the battle to gain control of the Organisation as her enemies appear to get the upper hand...
