Adrian Harvey, London wine merchant, has lost the Christmas spirit. Someone is stalking him, stealing his post and vandalising his shop. When the police question him after an anonymous tip-off, he's more than anxious. He's scared. And who is that nun? When long time neighbour and friend, DI Beatrice Stubbs is dispatched to Germany to investigate a series of apparently related art thefts, Adrian seizes the chance to flee the city. He follows her to Hamburg to do some Christmas shopping and visit his ex. Yet that stalker is still on his heels. While Beatrice is on the trail of a violent gang of mercenary thieves, Adrian runs from danger to the remote island of Sylt. But when danger catches up, he has run too far. From the icy streets of Hamburg, to the canals of Amsterdam, and the snowswept beaches of Sylt, Beatrice and Adrian discover how a virtue taken to extremes can lead to deadly sin. "Enthralling! The menace of Du Maurier's meets the darkness and intrigue of Nordic Noir. Keep the lights on and your wits about you." - Anne Stormont, author of Displacement
