The American President, on a planned visit to Europe, is entertained by the British Prime Minister on the terrace of the House of Commons. On the same day, London-born Mullah Ali Salim makes an impassioned speech at Hyde Park Corner accusing the President of war crimes, objecting to his presence and offering a blessing to anyone who will assassinate him. Dillon, Major Ferguson and Daniel Holley are called into action, helped by a new recruit, Intelligence Corp Captain Sara Gideon. Sara, a war hero in the Afghan conflict, specialises in Pashta and Iranian. They quickly find themselves trying to handle a massive upsurge in terrorism from enemies near and far, all with links to al Qaeda. As a Sephardic Jew from a wealthy and ancient English family, Sara will find herself at the heart of the firestorm when she is swept into the heart of the terror organisation. Dillon and company may have won the first battle with al Qaeda, but the war is far from over.
