William McBain

The Glasgow Police Force has been Charlie King's life. Tough, cynical and incorruptible, he upsets his superiors but gets results. When a heart attack grounds him, he jumps at the chance of a new arena for his skills: the twilight world between the Police, Special Branch, MI5 and MI6, where is works as an arms-length negotiator with national and international terrorists.

A charming, but vain divorce lawyer, who sleeps around, suddenly finds himself a changed man, after he undergoes an emergency heart transplant.
