1792. It's winter in Berkeley Square and the night-watchman comes across the body of silversmith Pierre Renard, his throat cut and his valuables missing. It could be common theft, but as news of the murder spreads, it soon becomes clear that Renard had more than a few enemies. At the centre of this web is Mary, the silversmith's wife. Ostensibly theirs was an excellent pairing, but behind closed doors their relationship was a dark and at times sadistic one. Mary is haunted by her past and near-mad with guilt. Will she attain the redemption she seeks and what does she need redemption for?
