"Jack Higgins has written some of the best suspense fiction of the past fifty years," wrote the San Diego Union-Tribune, and the Strand Magazine agreed: "With fresh plots, interesting characters and vibrant settings, Jack Higgins has firmly cemented his reputation as one of the world's most successful thriller writers." And in his new novel, a devil is indeed waiting....

The President is coming to London, but not to an entirely warm welcome. A fanatical mullah is offering a blessing to anyone who will assassinate the President, and though most London Muslims think the mullah has crossed the line, a few think otherwise.

Urgently, Sean Dillon, General Charles Ferguson, and the rest of the small band known as the "Prime Minister's private army" are called in, augmented by an extra-ordinary new recruit, an intelligence captain and Afghan war hero named Sara Gideon. She has her own contacts and ways of working, but the more she explores the threat, the more she discovers herself in a very dark place indeed.
