A British intelligence officer must win over a captured German scientist in post-war London.
Set in a bomb-damaged London hotel after the Second World War, Close to the Enemy follows intelligence officer Captain Callum Ferguson. His final Army assignment: persuade Dieter, a captured German scientist, to develop jet engine technology for the RAF.
With the Cold War emerging, such expertise is vital to Britain. Callum uses unorthodox methods to win Dieter over, and an unlikely relationship forms amid the suspicions and shifting loyalties of a world still reeling from conflict.
Around them, a cast of intertwined characters — Callum's brother Victor, former official Harold, American Anglophile Rachel, and war-crimes investigator Kathy — work to rebuild lives marked by a war that touched them all.
