Munich, 1935 - The Bavarian capital is a magnet for young, aristocratic Britons who come to learn German, swim in the lakes and drink beer in the cellars.

What they don't see - or choose to ignore - is the brutal underbelly of the Nazi movement which considers Munich its spiritual home. When a high-born English girl is murdered, Detective Sebastian Wolff is ordered to solve the crime. Wolff is already walking a tight line between doing his job and falling foul of the political party he abhors. Now Hitler is taking a personal interest in the case. Followed by the secret police and threatened by his own son, a fervent member of the Hitler Youth, the stakes have never been higher. And when Wolff begins to suspect that the killer might be linked to the highest reaches of the Nazi hierarchy, he fears his task is simply impossible - and that he might become the next victim.
