A gripping spy thriller for fans of ROBERT HARRIS and WILLIAM BOYD from award-winning Sunday Times bestseller Rory Clements and author of the 2018 CWA HISTORICAL DAGGER WINNER, NUCLEUS

1936. Europe is in turmoil. The Nazis have marched into the Rhineland. In Russia, Stalin has unleashed his Great Terror. Spain has erupted in civil war.

In Berlin, a young Englishwoman evades the Gestapo to deliver vital papers to a Jewish scientist. Within weeks, she is found dead, a silver syringe clutched in her fingers.

In an exclusive London club, a conspiracy is launched that threatens the very heart of government. When a renowned society couple with fascist leanings are found brutally murdered, a maverick Cambridge professor is drawn into a world of espionage he knows only from history books. The deeper Thomas Wilde delves, the more he finds to link the murders with the girl with the silver syringe - and even more worryingly to the scandal surrounding the Abdication . . .

Set against the gathering drumbeat of war and moving from Berlin to Cambridge, from Whitehall to the Kent countryside, and from the Fens to the Aragon Front in Spain, this big canvas international thriller, like C J Sansom's WINTER IN MADRID, marks the beginning of a brilliant new direction for Rory Clements.
