Set in a snow-dusted London, Mick Herron's taut thriller takes place in the gap where old-style spy craft and modern intelligence analysis don't quite meet.

When retired spy Solomon Dortmund sees an envelope pass from one hand to another in a bustling cafe he knows he's witnessed more than an innocent encounter. His shambolic handler has called in a favour and now analyst Alec Wicinski is on the trail of a German agent. But Martin Kreutzmer isn't about to give up valuable asset Snow White without a fight - no matter who gets hurt in the process.
