To Catch a King - Jack Higgins

1940. Hitler’s terrifying war machine will soon roll through England, and in its wake Hitler plans to enthrone puppet monarchs under Nazi control. For these roles he demands none other than the exiled Duke and Duchess of Windsor.

Berlin. Brilliant SS officer Walter Schellenberg is ordered to “persuade” the Duke and Duchess to the Nazi cause. But when Shellenberg impulsively aids the escape of beautiful Jewish nightclub singer Hannah Winter, he plunges them both into a dark arena of intrigue and betrayal. Hunted by ruthless Gestapo agents, chased through the deadly underground from Berlin to Madrid to Lisbon, they are racing on a collision course with their own loyalties – and the fate of all England.
