A murder mystery featuring Lord Edward Corinth and Verity Browne

It is February 1939 and Lord Edward Corinth embarks on his most important investigation yet. It is clear that Britain will soon be at war and will depend on Winston Churchill's leadership. But when MI5 learns that an enemy agent has been dispatched to assassinate Churchill, Edward is tasked with identifying the killer. His first port of call is the Astors' country house, Cliveden, the base of those who are prepared to go to any lengths to avert war.

Verity Browne is also at Cliveden, though she despises the so-called Cliveden Set. Communist Party bosses have ordered her to get close to another guest, Joseph Kennedy, the American Ambassador, who is convinced that Britain could never win a war against militant Germany.

Then the Ambassador's sons discover a man's body in Cliveden's grounds, Verity recognizes him to be a fellow journalist and as war looms, Edward and Verity enter a tense race against time to identify the assassin.
