The White Plague

by Frank Herbert

When an IRA terrorist car bomb explodes, the wife and children of molecular biologist John Roe O'Neill are indiscriminately killed on May 20, 1996. Driven halfway insane by loss, his mind fragments into several personalities that carry out his plan for him. He plans a gendercidal revenge and creates a plague that kills only women, but for which men are the carriers. O'Neill then releases it in Ireland (for supporting the terrorists), England (for oppressing the Irish and giving them a cause), and Libya (for training said terrorists); he demands that the governments of the world send all citizens of those countries back to their countries, and that they quarantine those countries and let the plague run its course, so they will lose what he has lost; if they do not, he has more plagues to release.

After releasing the plague, he goes to Ireland to hide, planning to offer his services as a molecular biologist in the hopes of sabotaging whatever work is done there on finding a cure. When he arrives in Ireland, he is suspected of being O'Neill (whom the investigatory agencies of the world have deduced is responsible). To travel to the lab at Killaloe, he is forced to walk with a priest, a boy who has taken a vow of silence due to the death of his mother, and Joseph Herity, the IRA bomber who detonated the explosive that killed O'Neill's wife and children; their purpose is to confirm his identity, either through Herity's indirect questioning, or the possibility that he will confess to the priest when confronted with the pain his revenge has caused for the boy.

Meanwhile, law and order have broken down in England and Ireland, and the old Irish ways are coming back. Local IRA thugs appoint themselves "kings of old", and others recreate ancient Celtic pagan religions centered on the rowan tree. The IRA has effective control of Ireland, but as the governments of the world grow certain that O'Neill is there and essentially in custody, they consider wiping out the three targeted countries to end the lingering threat.
