D: Heavy Water

1934. British journalist Owen Crisp-Upjohn is dispatched to Moscow, where his assignments quickly escalate from cultural reporting to international espionage. Before long, Owen finds himself pulled into the orbit of the enigmatic Earl of Suffolk, a maverick aristocrat, and Aurora, a curiously compelling women with a shadowy past rooted in Soviet intelligence.Their mission soon becomes clear: secure the world's only supply of deuterium - heavy water" - before it falls into Nazi hands.

The high-stakes pursuit takes them from London's plush drawing rooms to Barcelona, ravaged by the Spanish Civil War; from far-flung Soviet aerodromes to the perilous, icy landscapes of occupied Norway. Over time, Owen evolves from a detached observer into a man forced to confront profound questions of honour, love and moral responsibility as loyalties are tested and allegiances shift in an ever-tightening web of science and deceit.
