"The bell tolls at midnight as death requires it." But will it finally toll for Sean Dillon & company in the explosive new thriller of murder, terrorism and revenge from the Sunday Times bestselling author. In Ulster, Northern Ireland, a petty criminal kills a woman in a drunken car crash. Her sons swear revenge.

In London, Sean Dillon and his colleagues in the 'Prime Minister's private army', fresh from defeating a deadly al-Qaeda operation, receive a warning: 'You may think you have weakened us, but you have only made us stronger.'

In Washington, D.C., a special projects director with the CIA, frustrated at not getting permission from the President for his daring anti-terrorism plan, decides to put it in motion anyway.

Soon, the ripples from these events will meet and overlap, creating havoc in their wake. Desperate men will act, secrets will be revealed - and the midnight bell will toll.
