Mikali was a concert pianist, internationally famous and fawned upon wherever he went. Irresistible to women, too, yet always cold and withdrawn. He was also the most dangerous man in Europe, a ruthless assassin who killed not for principle or revenge - just for the satisfaction and excitement. Asa Morgan, originally a soldier monk, is also a killer who has perfected his techniques in many places, including the dungeons of Communist China and who is now a colonel in Northern Ireland, waging his war with controlled savagery. As Mikali flees the police after the murder of a prominent Zionist, he runs over and kills a young girl on a bicycle in a tunnel under the railway near Paddington Station - and the girl was Asa Morgan's daughter. For Morgan, there is only one solution - death.
