In a city built on secrets, who would kill to keep theirs hidden? The year is 1759, and London is shrouded in a cloak of fear. With the lawmen at the mercy of robbers and highwaymen, it's a perilous time to work the already dangerous streets of Soho. Lizzie Hardwicke is somewhat protected from the fray at Mrs Farley's Bawdy House, a reputable brothel. But then a wealthy customer is found brutally murdered... and Lizzie was the last person to see him alive. The magistrate's assistant, William Davenport, has no hard evidence against Lizzie, but his presence and questions make life increasingly difficult. Desperate to be rid of him and prove her innocence, Lizzie turns amateur detective, determined to find the true killer, whatever the cost. Yet as the body count rises, Lizzie realises that, just like her, everyone has a secret they will do almost anything to keep buried...
